The Greater Gardening of 2026 – Part 21 – Testing Tomato Trellises


I had such a surplus of tomato plants this year that I decided to make another makeshift shelter to grow them outside the greenhouses.

I used the portable trellises to do so by wiring five pairs slightly offset to stand in an A-shape and then using the last pair for a roof to support the plastic foil. I then planted the tomatoes between the A-shapes so when they start to grow in height, they can lean on the trellises. We shall see how this goes. The biggest problem could be temperature. If the summer is too cold, tomatoes won’t grow outdoors fast enough. The second big problem could be sunshine. This area gets only about 6-8 hours of direct sunshine; the first half of the day it is in shade. In my experience, tomatoes do not actually need direct sunshine to thrive; temperature is more important. But like all plants, they need enough light to photosynthesise, and I am not entirely certain they will get it here. Well, we shall at least see if these trellises work for this purpose.
