    Spring is fully on at the farm and all over town. Forsythia and Rhododendrons are flush with color. Daffodils are lining streets in white and yellow. Maple trees are letting everyone know they are ready by dropping blankets of pollen on everything. How are those allergies?

    Hope everyone had a wonderful Easter weekend, we are back in the swing now and the heavy rains that have been predicted seem to be staying at bay. It is letting us get some real work done and start to spread to some more diverse realms.

    First, this weekend please join us for a wonderful close out to our April Workshop Season. Dianne Porcello will again be reprising her talk on Container Planting. This is traditionally our most sought out and popular workshop.

    This container holds perennial succulent ice-plant and rock cress. It is perfect for a sunny and dry corner where you want some early color. Come on in to find out how to put it together to match your home color scheme.

    Dianne will go over the basics of mixing plants and colors in containers to create beautiful planters that will be successful in your yard. She will go over plant requirements, and even the basics such as choosing soil, fertilizer, and how to water.

    She will also go over some of the new trends in containers, including making perennial planters, using unique foliage plants, and succulents. Bring your questions and an itchy, if not yet green, thumb and be ready to start the month of May off with some hot new looks for your porch, patio and window boxes.

    You can use a container to show off an explosion of colors, or you can be restrained and keep it in a color family, like this cool shades of violas container in a patina colored pot.

    The workshop starts at 10 am, in the large Greenhouse and afterwards you will receive your 10% off coupon to use right away on your own container ideas. As always the workshop is free, we just want to see you!

    In other news we have been getting some things going out in the field. We recently took the mulch off the strawberry crop, so the plants could get some access to the sun. We have the early peas, corn, and beans in the ground and all of them have been covered with floating row cover to help keep them toasty and these still cool nights. In fact thanks to the paper covering the peas are already up and reaching for the sky. The first spinach and Swiss chard seedlings are starting to peek through the soil as well.

    The first peas crack through the soil at our Standish Rd. field last week.

    In perennial crops the rhubarb and mint beds are looking pretty lush. And the blueberry crop is showing signs of life, which is great after such a harsh winter. We are battling to get the new asparagus in the ground but some fields just don’t like to be dry when they should be. We’ll see how that works out, but we are definitely excited to get this new crop started.

    The scraggly leaves sticking out through those holes will eventually be strong green tubular leaves, attached to some sweet and hopefully large onions on the bottom.

    We have been working on something else new for us this week. Onions. We have really wanted to be growing onions for a while and we think we have a cost-effective way to do it. At least we are trying it, it is a near guessing game for us, but we have gotten some great tips from some of our other area farmers. Anyway, we made some raised beds in the field and covered them with plastic mulch. We spent today punching holes every six inches and dropping in transplants of our own onion seedlings and some larger ones we bought in that had been field grown.

    We use a tractor to install plastic mulch for the new onion crop to aid in keeping it weed free. It lays a line for trickle irrigation underneath as well.

    These should be a decent size by mid to late July, and we will hopefully have some nice bunched fresh onions to offer you this season.

    In case I forget to mention it, new hours start on Sunday, extended for the month of May to make it a little easier to get your yard work accomplished.

    Posted by Volante Farms in Theme Additions on

    As we have been showing you the last few weeks, there are a host of plants blooming already, perennial perfection for your garden that you can plant now for early spring color and that will come back again year after year. Many of these have already been blooming for weeks, with time to spare, so if you really itch to kick the winter blues on out the door every year think about adding some of these to a few spots in your yard.

    Choose an early bloomer like yellow Forsythia or the bright purple of the earliest blooming Rhododendron, the P.J.M, for easy visibility from your kitchen or driveway, to be sure to give you a lift. Maybe pick a small part of your perennial garden that you walk by every day regardless of season by a front walk or mailbox for some of these early perennials like Candytuft and Rock Cress. These early perennials don’t invest their energy into lots of growth before flowering as they know they are the only game in town for winter hungry pollen seekers, so you need to keep them handily located so you don’t miss their special precocious shows.

    No reason to wait til the heat to come on. Stop on down before the mad rush of May to choose from our many locally grown and area appropriate perennials. [slideshow]

    Many thanks to Paul Lopes from UMass Extension Services for coming down today and educating everyone on ways to prevent common garden ailments! He began by talking about how important soil composition is, and that roots need both water and air to grow healthy, strong plants. The enthusiastic group of attendees asked Paul all of their gardening questions, steering the talk toward tomato diseases. He educated the group on blossom end rot and proper watering techniques for lawns and vegetable gardens. Watering mid-day is best, so that the plant leaves have time to dry off before the night sets in. He also mentioned that it’s best to avoid watering first thing in the morning so that the dew has a chance to evaporate.

    Composting was another topic of conversation, and Paul offered great tips to the home composter.

    If you missed Paul’s talk, not to worry. We have posted links to all the information from his handouts below.

    Home Composting – a great guide to help you start composting at home – includes how to compost both yard waste and food waste!

    Fertilizing your Vegetable Garden – All the basics, including an explanation of the elements that make up soil, understanding pH, and different ways of applying fertilizer. This guide also has a great section of sypmtoms for nutrient-defficient plants which is helpful to diagnose certain garden problems.

    Soil Testing – Want to get your soil tested? If you missed our free soil testing day on the 16th, don’t worry! UMass Amherst offers reasonably-priced soil testing through the mail. It’s easy: just fill out their online form and send your soil in!

    Next week’s free workshop is Container Gardening with Dianne Porcello. This workshop is one of the most widely-attended each year! It’s a great way to wrap up this year’s spring workshop schedule, so be sure not to miss it. As always, it will start at 10am in our beautiful greenhouse and you’ll get a 10% off coupon for participating!

    Until then, have a great weekend and let’s keep our fingers crossed for sun and warmth next week!

    It is a busy week with a host of holiday events. And speaking of hosts, have you been recently or are you expecting to be hosted for a fine meal soon? Don’t forget your attentive and exquisite host. Arrive graciously with a prepped to bloom Easter Lily in hand. Perhaps you know their taste is not quite as austere as the white lily. well there are a wide variety of ready to grab and go gifts down in Volante’s greenhouses. A small pot of pansies or violas are perfect for the season. Spring bulbs such as tulips and daffodils will bring an instant hit of color, and can be planted in the yard for vibrant hues year after year. We even have some luscious perennial mixed pots already grown in and flowering now.

    So, what I am saying is there is no excuse. If your mother checks our website too and realizes we were in fact open everyday (except this Sunday) and you still didn’t walk in the door with something to show a little appreciation, well don’t come crying if your lamb is missing its mint jelly. Or did you attend a particularly nice Seder and would like to show your appreciation? Come on down. Let’s start Spring off right, apparently with a lot of guilt from me. Hey if it works. See you soon, and here are some photos of some lovely options.

    So you have your pansies in the ground I hope. It was a perfect weekend for it, with a little touch of rain to set them in and temperatures they just love. Maybe you even have your yard cleaned and mulched? No? Well you know what comes next then.

    But maybe you are itching for more planting. It feels so good to start working the ground in the spring it can be a bit disheartening waiting for those warm “safe-to-plant” days a few weeks away. So what can you do? Perennials! Shrubs! Succulents?

    For something fun and different, give a succulent a try. Named for the reserves of water in their leaves and stems, succulents range from aloes and cacti of the deserts to the portulaca and purslane weeds of our fields here in New England. Growing in popularity due to their ease of care, succulents make excellent container plants in and outside of the home. Many of them are ideal for rock gardens and filling the nooks and crannies.

    We have beautiful perennial Hens&Chicks, Stonecrop and Sedum for your outdoor garden, as well as some lovely mixed containers of non-hardy varieties for your home with aloes and other types.

    Stop in and check out some of these easy on the water options, keeping in mind these April showers aren’t here for ever, but these beauties are ready to grow now.[slideshow]

    Comments Off on Soil: we’ve plowed our fields, have you?
    Posted by Volante Farms in Theme Additions on

    Big week on the farm. Last Thursday we got down to business out in the fields and plowed a little land at the home field and a little more at the Standish Road fields. By Friday evening we had the first crop of peas in the ground, and along with them carrots, beets, scallions, parsley and Swiss chard. Today we began plowing and prepping ground for the first corn of the year as well, and if the weather cooperates it should be in by tomorrow morning.

    In the greenhouse we have gotten a majority of the spring flowers transplanted and growing their way toward your gardens. Pansies are continuing to flourish and fly out the door. This week we have begun transplanting more of the summer vegetable crops, specifically peppers and eggplant, into trays for customers.

    Matt Griswold at last Saturday's Perennial Workshop

    Hope you made it to our workshop Saturday, it was a great turnout, and we were able to host it out under a warm sun for a change.

    This weekend we have two events going on. Our free 10 am workshop is with guest speaker Jody Gilson of J. Gilson Greenhouses in Groton, MA. She will help you plant a container salad. With instructions and tips on how to combine herbs and greens in a patio pot to deliver delicious salad all summer long. Attendees will as usual receive a 10% off coupon to use over the weekend.

    Additionally on Saturday we are again offering Free Soil Testing from 10AM-3PM with John Howell from the
    New England Vegetable and Berry Grower’s Association. We ask that you limit yourself to two samples per customer. It helps if your samples are dry, so you may want to collect them from two spots before we get too much rain this week. One from the lawn and one from the garden is a good place to start, and you don’t need much. A cup or so of each should be plenty. Hope to see you then and before then.

    Comments Off on What are these packets all about?
    Posted by Volante Farms in Theme Additions on

    Bugs!

    You will find these small packets throughout our greenhouses this spring. What at first may appear to be trash, are actually part of our new biological pest control problem. These packets contain a mixture of bran and two types of mites. One of these mites loves to feed on thrips, which are an insect that damage many types of plants in a variety of ways. The packet continues to work for 8 to 13 weeks from the date stamped on it. This one for example is from February 9, meaning the predatory insects inside are still hard at work this week and for up to 5 more. Right through Mother’s Day perhaps. If you like please take the packet on your plant home where it will continue to protect your plant for weeks to come, or if you prefer a cleaner look, give it to us at the register and we will dispose of it. The sachets are all paper with only insects and bran on the inside, so they will biodegrade in your garden or compost bin.

    For more on our fantastic biological control program, click on the page describing it to the right or delve into the previous post, which is a thick and thorough discussion of what we are doing in the greenhouse.

    Posted by Volante Farms in Theme Additions on

    I have been looking forward to the post since last year, once it was determined that our pilot program in biological control of insect pests was a success. I can happily say that we have reduced chemical use in the greenhouse by about 95% or greater within only a years time. As it happened last year we were a bit behind the eight ball when we started and we were not starting with a clean space, but now, this year we were ready in time and met all of this season’s plants with the appropriate methods.
    Now while we are still getting the hang of the system, it does seem to be working again this year, and the problems we have seen so far have been checkable by quick response. I realize already that this is beginning to sound very abstract and rambling, so maybe it is time for a brief refresher.

    Our new pest control program. Shows up once a week in boxes full of air holes.

    Historical Pest Control

    In the past we have relied on a variety of insecticides and fungicides to finish the plants in our greenhouse to a successful point prior to your taking them home. We did this as part of the Integrated Pest Management (IPM) program which we are still involved in, which constitutes a weekly scouting of the greenhouse space to determine what pests there are, if any, and whether or not we have reached a critical point in which we would need to treat with chemicals.

    These yellow cards are coated with a very tacky glue that attracts insects seeking pollen to its color and then traps them in place. We scout the cards often and get a count of total insects by type once a week. This allows us to determine if the pressure of the pests in our crops warrants further treatment or if the totals fall below the danger threshold.

    In order to do this we would stay after closing hours and certified applicators would use expensive equipment, with expensive chemicals on expensive time to solve the problem. If successful treatment resulted in a clean plant we could be happy, but as you may have heard many of the pests that we have begun to encounter in the industry have become resistant to the chemicals that are available to use. This is due in part to a limited number of chemicals that are considered safe for the environment and the people using them and the fact that each time a pest is hit with those same limited chemicals it can gain some resistance to them. The old adage “What doesn’t kill them makes them stronger” is completely accurate for the insect pests in our greenhouse.

    The Pests We Focus On

    In our spring and summer greenhouses there are a few pests we focus on and a few more that are peripheral nuisances we are concerned with. Aphids are the insect you are probably most familiar with as a home gardener. The tiny and bulbous insects spend nearly as much time creating offspring as they do devouring plants and being vectors for disease. There are a few hardcore chemicals which work on aphids, as well as some certified organic compounds like insecticidal soap. This insecticidal soap is a great option for control in your home garden as it is safe and effective. In our greenhouse we are going a different route as these chemicals would conceivably harm some of the beneficial insects we have cultivated as well.

    This is a 100x photo of one of the potato aphids that caused us to fall behind in pest control last year. Notice the antennae that extend beyond the body. These differentiate them from the cereal aphids we have on our banker plants.

    Thrips are the other insect we are investing a lot of energy in preventing. You have probably never seen one of these tiny flying insects, but in fact it is one of the pests that creates the largest problem for the flowering plant industry. Thrips live in the soil and on the plants in their larval and nymph stages, and once they reach adulthood they can fly to a great distance. They feed on the pollen and plant matter in many of our most popular plants, often leaving a damaged leaf or a shriveled and misshapen flower and failing buds. The threat of thrips has actually been the impetus behind many growers in our area to go toward a biological controls as thrips in the U.S. were resistant to the chemicals that used to work on them within a year of those insecticides being approved for use here. This is due to the increasing globalization of horticulture and plants that used to be propagated locally were now coming from further and further away, sometimes infested with pests that were already resistant to the strongest chemicals.

    Thrips are a threat to almost all types of crops due to the variety of diseases they spread.

    We have a history of fungus gnats and shore fly as well, which up to this point have never been much of a threat to us, or more so, we have never done anything about them. The more we learn about the intricacies of how biological systems work together the more we find that it is pretty likely they are the causes for some of the diseases we do get from time to time.

    The last pest we fight most regularly is not an insect at all, but a bevy of fungi. Botrytis, Powdery Mildew, Phytophthora are just a few of the nemeses we face in the greenhouse. They thrive in humid and warm locations and can take out a single plant or a houseful in a matter of days. We do most of our fungus fighting through ventilation and clean growing practices, which has been made easier in our newest greenhouses with their multiple options for air movement and moisture removal. But we still need to consider chemical fungicides a possible and useful tool to combat breakouts.

    Our Present Biological Program

    We have been working with BioBest, an international company based in Belgium and Canada that specializes in biological pest controls. We have close contact with their sales and advice departments, to the point that they will probably soon tire of our questions, if they weren’t also really into their product.
    What we have set up is a combined effort of primarily defensive protection and when necessary a directed offensive. We treat every plant cutting or seedling that comes into the farm with preemptive beneficials, and we treat every space that will house plants with healthy doses of both predatory and parasitic creatures.

    This is one of a few dozen banker plants around our greenhouses. They are planted with barley, a cereal grain, and covered in aphids and their sticky honeydew. Many of these aphids have been parasitized already and are preparing to hatch into more colemani wasps.

    Aphid Control

    This is one of the most fun control methods we are employing, mostly due to its existence above a microscopic level. So many of these controls take place on such a tiny scale one really needs to suspend disbelief and hope they are working. But with aphids it is all real and in your face. In fact to combat aphids we go to the extreme step of bringing the enemy into our home. Ok that sounds absurd, but what we do is create a breeding program for cereal aphids, which we raise on barley plants throughout the greenhouses. The thing about cereal aphids is that they don’t care about the majority of the ornamental plants that we raise in our houses, except for a few fancy grasses. They are however similar enough to the green peach aphid which is one of our greatest foes. This is where a miniscule wasp, about the size of a small mosquito come in.

    This is an aphid that is mummified,or implanted with a coelmani wasp's egg, on one of our banker plants, at 100x magnification.

    This is another mummified aphid, that was parasitized further along in its development. Notice it already has wings. It will still provide a healthy wasp in a few more days.

    This is two mummified cereal aphids. The larger has a hole at its back end. This circle is cut by the wasp's jaw from the inside out when it ready to emerge.

    The colemani wasp places its egg in a living aphid, in which it grows and turns the aphid into a mummy, or incubator for the pupal wasp. This leaves a once green aphid an empty brown hull once the young wasps cuts its way out and proceeds to parasitize countless other aphids. The reason we offer these “banker plants” lush with cereal aphids is to insure that the thousands of wasps we release into the greenhouses have a host for their eggs in case there are not enough actual pest aphids present in the growing space.

    These colonies will keep themselves populated throughout the spring so that there are several generations of young wasps hatching to seek out new hosts for their young. So when you see a pot of grass hanging low with sticky aphids and honeydew, actually be relieved that we know and we are doing it on purpose. Those ugly baskets are chemical free gold in our greenhouses.

    These dark spots are aphids- some alive and some already mummified.

    While these tiny colemani wasps will parasitize more than 40 types of aphids they do not go after the many types of long-legged aphids that we also are confronted with, like the foxglove or potato aphid.

    This is a close up of colemani wasps hunting aphids on the banker plant. The wasp appears to be a small winged ant in the middle of the photo, in relation to the rounder aphids on the barley grass blades.

    This is where we got into trouble last year as we didn’t realize quickly enough that we needed to be aware of the type of aphid infestation we were under. Now we know that to combat these other aphid types we can’t set up banker plants of parasitoids but instead need hungry predators. A slightly larger wasp, called ervi, is a tireless carnivore of potato aphid and we have recently released some in the big greenhouse just to clean up the edges.

    Predators are not as dependable at finding their prey so it is helpful if they can be placed in the heat of the problem, being ever hungry they move on quickly if the food isn’t right in front of them. We last year also had little colonies of midges hanging out in styrofoam cups around the greenhouse. We so far this year have not had a need to introduce these little aphidoletes, but they can be brought in if we encounter an infestation. Watch the video below to see one of our own colemani ravaging a barley blade, or click the link at the top of this section to watch one actually parasitizing aphids on BioBest’s website. Theirs is a little less out of focus.[wpvideo 3FTYx4te]

    Thrip Control

    So as I said, thrips are one of our greatest pests, though you wouldn’t be able to tell this spring. We have invested a lot of energy, thought, and money in keeping their numbers in check this year and it is paying off. The first method we employ is a healthy bath. This bath is spa-like in a way, if you enjoy spas that let you soak in millions of microscopic worms. Or nematodes to be more exact.

    These nematodes are microscopic enough that you never need to worry about the thought of them crawling around on you. 50 million of them in a gel suspension would fill only about 4 ounces of space.

    Steinernema feltiae nematodes are a natural predator of fungus gnat larvae, but also an avid consumer of thrips at all stages except for the egg. We dip every plant that comes to us as a transplant in a suspension of 50 million nematodes in 12 gallons of water. This deposits nematodes on the foliage and in the soil of the incoming seedlings giving them ample opportunity to parasitize any existing thrips on the plants. When we have a likelihood of infestation, I am able to treat an afflicted crop with a spot treatment of nematodes through our Dosatron, a fertilizing and chemigating machine. If performed on a cloudy day or in the evening the extended time that the foliage stays wet allows the nematodes to get their business done. This has proven to keep our incoming plants clean and our self-raised ones healthy too.
    We apply a multiple of mites to the greenhouses as well in the control of thrips. Mites are tiny arachnids which can cause all sorts of problems in your life. Dust mites are responsible for many Americans’ allergies and spotted spider mites are one of the major vegetable crop pests we fight in the fields. However there are some types of mites that can be extremely beneficial. We apply hypoaspis miles to each of our greenhouses at the start of spring. This mite feeds on both fungus gnat and thrip larvae, and does wonders to cut down on populations that may have overwintered in the greenhouses.

    [wpvideo s8nxH0Ue]

    This is one of thousands of sachets containing mites and a bran mixture. The active thrip killer in here is the female cucumeris mite, 50% of which leave the packet to seek out food.

    You will never see hypoaspis miles in action, but know they are there. Who you will meet are the pair of mites in our paper sachets. These paper pouches have been applied to nearly every hanging pot, flat of bedding plants, and container on the farm. Last year we applied small spoonfuls of bran and mites to each plant,and this year in an effort to standardize and streamline the process we have gone with a system that has the two types of mite already contained in a single pack. One is a feeder, one a food source, and bran, a food source for the feed mite all combine in a sawdust like mixture inside the paper sachet which has a small hole in one side. From this hole about 25-50% of the cucumeris mites will emerge to seek out thrips on their host plant. The rest remain in the pouch feeding and breeding more predatory mites to exit over the next 8 to 13 weeks.[wpvideo 27R58h0Y]

    This shows the relative size of the bran contents of one of the sachets. Compare it to the bran in the video to see how amazingly small our "bugs" are.

    When you take your hanging plant or Impatiens flat home and you notice this paper pouch laying on the soil you can do a number of things. 1. Use it, the pouch will continue to provide insect protection for your plant for up to 13 weeks from the date printed on it, enjoy the added punch of protection to your home garden. 2. Toss it out. Hand it to us at the register, or throw it away when you get home. 3. Let it do its thing into oblivion. The pouch is all paper and the contents are 100% natural so let those mites work their magic and don’t give them a second thought. The sachet should biodegrade over time in the garden. So there you go, set it and forget it.
    This year, in exciting bug land news, we had a possibly serious thrip infestation in our early crop of fuchsia hangers. These thrips could have damaged and created disfigured blooms on your mother’s favorite Mom’s Day Gift, had we not brought in the big guns. And by big guns, I mean cannons. And by cannons I am alluding to the Pirates, or Pirate Bugs, or orius insidiosus.

    Orius Insidiosus, or Pirate Bugs. This one swabbing the deck of my thumb. We were very impressed by the thoroughness of their pillaging in our fuschia.

    Yeah, we had a lot of fun releasing these swashbuckling little bandits on the situation. And lo and behold, they worked! Within a week we went from scouting up to 10 thrips a day on one sticky card to 1 or less. Hopefully we never find their treasure chest with all those carcasses.
    We also introduce atheta coriaria into the greenhouses in early spring. These are also known as predatory or rove beetles. They are fast to dig into the soil where they will travel far and wide seeking larvae of shore fly and thrips to feed on. Just a final and additional step in making sure our pest problems are kept in check.

    Rot Control

    We are taking advantage of our chemical free proclivities to reduce the amount of chemically based fungicides we need to use in the greenhouse as well. As a companion to our nematode system of treating all incoming plants we have included the product know as Rootshield in all of our suspensions and as a post transplant drench. This is actually a beneficial fungus that latches on to the roots of the target plant. This plant then thrives as the root locked fungus prevents other harmful fungi and mildews from breaking into the root system at a later date. The fungus comes as a powder, and smells like toasted mushrooms in a way.

    Open for business

    So it has taken me a few weeks to compile this article, and in that time we have opened for the spring season. So you may have had a chance to see some of this program in action. What I can say so far is that we have for the first time in my memory opened without having used any chemical insecticides whatsoever. This is a great and positive step and I hope you enjoy the efforts we have made in this respect, to reduce the amount of chemical in our greenhouses, and ultimately at your home. This is still a flexible and growing program so if you have questions about it or want to express your thoughts, please feel free to stop in and ask us about it. I am just about to the point where I can speak with some knowledge on it, so I am happy to talk to you about it. Thanks a lot for your interest and get down here soon to check out these super clean and super healthy plants for your garden.
