Controlling Growth in the Polytunnel

Many of the plants that I grow in the polytunnels in the summer need to be tamed, usually by pruning and stringing up, in order to get a decent yield out of them. And this year I have used a few different techniques and bought some materials and small pieces of equipment to help with the task.

    After trying a few different methods, I've settled on letting three stems of my indeterminate tomatoes grow up jute twine tied to an eight foot tall frame, with the tops attached 20 inches apart. In my growing conditions, this is about the right amount of foliage to slow the increase in height to the point where they reach the top of the frame close to the end of the season. Single or double stems just grow too fast, quickly surpassing my reasonably comfortable reach. Three seems to be the magic number.

    Thanks, that is really interesting. I imagine that would be a lot easier to manage. Do you plant the plants 60cm apart? I definitely want to explore a few different options next year. I have heard of a method where every third side shoot is left to grow up a separate twine, because apparently every third one tends to be stronger. Perhaps only a few of the stronger ones, rather than the lowest two side shoots might be an interesting option.

    @@REDGardens I've just been using the three strongest shoots that start about 30 cm off the ground. I hadn't heard the "every third shoot" theory, but I may try that on a plant or two as a test. I figure this gives the three stems the most air and light as they grow, with the side ones hanging and spreading a bit, while the center goes straight up. I'm experimenting with different planting spacing and orientation. Next season, I want to try a single row of plants down the center of a meter wide bed, but only 40 or 50 cm apart. The three branches would spread across the width of the bed. Up to now, I've been doing two rows in the bed, with much greater spacing, and the branching spreading along the length of the bed. I figure if I rotate that orientation 90 degrees so that each plant has the full width of the bed for its resources, they can be spaced relatively close together. Spatially, I think it will be less chaotic.

    I think it's a good idea to re-use the plastic clips despite their biodegradablilty. Certain bio-plastics, while biodegradable and made from renewable materials, can have a significant environmental impact. Life cycle analysis work has found that the land, water, and energy use can be greater than that of some conventional petroleum based plastics. The increased energy use can mean the bio-plastics have greater greenhouse gas emissions than conventional plastics. The biodegradablilty however is a clear advantage, seeing your microplastics in the garden video was alarming! Due to the trade-offs I can't attest to whether you should use petroleum or biobased plastics but I do encourage the re-use of bio-plastics due to the greater energy required for their production. If you want more info I can dig up some references. Cheers and thanks for another helpful video.

With the clips I think it will likely be longer, but I don't really mind how long it takes as long as they aren't persistent in the compost or soil. If the ones I drop into he soil in the gardens and end up in the compost disappear eventually, without leaving any problematic compounds or micro plastics, then I am happy.

    Most of the modern tomato varieties have been bred to be so vigorous growers that they almost need to be grown in a situation where the ratios of nutrients (NPK) can be controlled extremely precisely (computer-controlled greenhouse). Their growth will outstrip the ripening of the fruit. Your solution is a really good one. Another might be to construct a sawhorse-type supports that hold them up from below. In a commercial greenhouse, they use bent wire supports attached to the growing bench.

    I reccomend pruning the bottom shoots on pepper plants in temperate climates because they have evolved in the tropics and semi tropics where they have a much longer growing season. Also, pick peppers as soon as they are ripe so the plant keeps producing more. I live in Colorado and grow many chilie varieties in our short, dry and hot growing season.

    Tomatoes can actually be one of the trickiest things for home gardeners to grow. For example, if they wilt even once, it checks the plant and will lessen the crop, It's much harder to grow them in pots for this reason - you need extremely big containers for them and be watering the plants religiously so they don't wilt. They could even need watering several times on very hot days. They're also prone to heaps of pests and diseases - I'd say the three most important things are: watering meticulously, feeding little and often, and giving them enough sunshine. yours are being eaten because they're somehow stressed and weakened. Keep at it though - if you get it right, they're also possibly the BEST and most delicious thing to grow yourself! 🍅🍅🍅🍅

Obviously it's always better to have a commitment from people so that you can plan for it, however it might be a good way for a bit of extra cash to come your way every now and then in support?

    I think greenhouse space is too valuable for growing squash. I start my squash in a large cold frame. It was 4x8 feet now it's closer to 6x12 (2m x 4m) and disassemble it when they start growing out of it. When squash vines grow along the ground they put down roots which must be beneficial to how big and numerous the fruit is.

    I really should do a proper video about it. Basically, I prune the side shoots leaving only a main stem that I wind/clip onto a twine suspended from the structure with a tomahawk (or you can just leave extra length of twine hanging). Then when the plant reaches the top of the polytunnel space, I tie a second piece of twine to the stem of the plant at about waist height and tie this to the structure above. Then I let out more of the twine and more the tomahawk or knot over to one side so that the middle section of the plant is slightly horizontal and the top part goes vertical again. This continues as the plants grow, and they end up overlapping with the plant next to it in the row. I have begun putting in an extra clip when it crosses the next secondary twine - or add additional pieces of twine to support the plant where it is running horizontal.
