New Concepts for the Winter Harvest

Eliot Coleman Bio

On the verge of winter here in Eastern North America, author and Johnny's tools advisor Eliot Coleman shares his thoughts on trialing different concepts and technologies in unheated greenhouses over the coming winter production season .... 

by Eliot Coleman
One of the joys of farming for me is searching out better ideas. This is especially true for the winter production of cold-hardy crops in unheated greenhouses, a production system that we have been exploring for 35 years or so. We are always looking for new ways to keep the greenhouses warmer at night without spending money on heat. We will be trialing two promising products this winter.
The first is SolaWrap, a greenhouse plastic that looks like bubble wrap, which has been in use for 30 years in Europe but has only just this year been released to the US market. We are most interested in its superior insulating quality, compared to sheet plastic, in order to keep heat in the greenhouse. It is -inch thick and has an R-value of 1.72, which is superior to the expensive triple–wall polycarbonate. We also appreciate that the material comes with a 10-year guaranteed lifespan.
But probably the most unique property of SolaWrap is the way it is put on the greenhouse. With sheet plastic, the growers and their crew will work frantically to cover the house with one huge piece. I say “frantically” because the process becomes extremely difficult if there is any wind at all.

SolaWrap Roll-up Curtain

SolaWrap, on the other hand, is modular. It is independently attached between each pair of ribs. SolaWrap is available in 4’, 5’, and 6’ widths, which you choose depending upon the rib spacing of your greenhouse. A cable is welded into each edge of the SolaWrap width. A hard plastic strip, with a slot along each side, is first tech-screwed onto the top of all the ribs. To start installing, the cables are inserted into the slots and the SolaWrap is pulled up and over the greenhouse, one pair of ribs at a time. The slots hold the cables so securely that people can stand on the plastic.
Water Wall
Our second trial this winter also involves an effort to store more of the sun’s daily heat in the greenhouse to keep it warmer at night. We will be using 12”-diameter, water-filled black plastic tubes as our heat storage medium.

Ginegar Water Wall

European greenhouse growers have employed this concept for many years by laying the tubes on the soil between the rows of crops, down the length of the greenhouse. That has been beneficial for two crops they commonly grow, tomatoes and cucumbers (two crops not on our unheated winter list); but using them that way would be impractical for our closely spaced spinach and salad crops.
However, the Israeli company Ginegar has developed a water tube designed to be held vertically in a simple wire mesh support. With the vertical configuration, a whole row of them, side-by-side, can stand out of the way against the north wall of the greenhouse. In a 50’ house that is about 2000 gallons of water.
Will the water-filled tubes freeze solid in the depths of our Maine winter? Would that be a disaster or just a temporary situation? Will we miss the ambient light that used to come from the north side of the greenhouse? Well, that is part of the adventure of exploring new ideas — you never know how things are going to turn out until you try.

Cedar Ridge Resident Facility Garden

The Cedar Ridge Center, a Johnny’s customer located in Skowhegan, Maine, recently sent us the following review of their successful growing season. Cedar Ridge is a newly renovated, 74-bed facility offering full rehabilitation services, an enhanced meal plan, and 24-hour skilled nursing care.


The Cedar Ridge facility’s garden was a project that was started in the spring of 2013 with the assistance of Master Gardener Robert Turner, Johnny’s Selected Seeds Contact Center Specialist Erin Reardon, and the activity department at the Center. Seeds were purchased through Johnny’s in Winslow and started in the facility under grow lights.

   Last spring, the turf at the facility was taken up in 5 strips, 7 feet wide and 50 feet long. This year we added 3 more strips, for a total of 8. The turf was left between the rows so that our residents’ wheelchairs could access the entire garden. 

   Through the direction of Master Gardener Robert Turner the project was taken on with sustainability in mind. No fertilizers were used to amend the soil. The residents assisted with watering, potting seedlings and then, after harvest, they snapped beans, peeled vegetables, and have made pickles and squash pie. 

   Residents have enjoyed watching the garden grow and showing off their garden to family members. The garden for the past 3 months has produced 1,187.58 pounds of fresh produce! Our facility kitchen staff has taken great pride in preparing the backyard fresh vegetables and the residents compliment daily about how much they have enjoyed them. This is a project that speaks of the memories and tastes of home. We have raised broccoli, cauliflower, peppers, tomatoes, cabbage, carrots, cucumbers, green beans, summer and winter squash, zucchini, Swiss chard, and lettuce and added raspberries, blueberries, and asparagus this season.

Winter Trials Summary: Lettuce, Greens, and Herbs

At the end of last year (2013) we conducted two winter trials on specific types of Lettuce, Greens, and Herbs at our Research Farm in Albion, Maine. Steve Rodrigue, the Johnny’s Product Technician who oversaw the trials, summarizes the process below:

The overwintering trials took place in two of our caterpillar tunnels at the Johnny’s Farm. The caterpillars we used were slightly different from those we offer via the catalog and online, because they have both end walls and side roll-up walls. With roll-up walls, we were able to ventilate much more throughout the trial - until the snow eventually prevented us from doing so. We had several small trials happening in the tunnels, which included  Salanova Lettuce, Baby Leaf Lettuce, Greens, Spinach, and Cilantro

   The Salanova performed very well and lasted into the New Year. For that trial, we had two different seeding dates at two weeks apart. The earlier seeding allowed for the plants to grow to a marketable size whereas the later seeding and transplanting did not mature before going into the Winter. This is another indication of how important it is to experimenting with several seeding dates.
   We had some issues with Bottom Rot with the Salanova, but we felt that was due to inadequate ventilation. Moving forward with our future overwintering trials, temperatures will be monitored several times throughout the day in order to best time the removal of the inner covers (agribon). Also, while the caterpillars did a fair job at protecting the crops through the harsh winter, we found them to be more of a challenge for adequate temperature regulation than a Hoophouse or High Tunnel. The short height and smaller volume of the Caterpillar Tunnel results in much larger fluctuations in temperatures, which means you have to do a lot more regulating of the temperatures.

Banker Plants

Protected culture structures, such as hoophouses and greenhouses, are by nature limited in growing space. Many growers make the most of the available space by planting crops that have high returns; i.e., tomatoes, cucumbers, peppers, and eggplants. In a closed environment, it is also well worth it to put a little of the area aside for banker plants.

Any crop that provides a habitat for beneficial insects can be used as a banker plant. One of the greenhouses at Johnny’s research farm is dedicated to peppers and eggplants — both of which are susceptible to predation by aphids. In addition to the peppers and eggplants, space has been reserved for containers of oats which serve as banker plants by providing habitat for oat aphids. The oat aphids are released into the oats, which are then covered to allow the population of the pest to grow.

Why would someone release an aphid of any kind into their greenhouse and then build their population? The oat aphid is host-specific to only oats; it won’t attack any other crop. At Johnny’s, once the oat aphid population has grown, Greenhouse Manager Pam Carter releases parasitic wasps that attack aphids of all kinds, including those that pose a danger to the peppers and eggplants. As a side benefit, the oats can also provide habitat for ladybugs, another beneficial insect and predator of aphids.

For those of you with concerns about the use of insecticides, banker plants are a practical alternative. In many cases the resulting natural controls by beneficial insects will reduce the need for insecticidal applications.
