One of the coolest things about a community garden is seeing how people garden differently and learning from their experiences. We share a few collective plots in our garden for the food bank & shared harvests. One of these plots has turned into an experiment in vertical squash production. A fellow gardener built a trellis from salvaged material for the collective winter squash.
I have been peripherally interested in trellising squash for the past two years. The sprawling vines of a squash plant take up a lot of room, so growing it vertically saves quite a bit of space and I suspect the vertical space provides extra ventilation to help with the mildew that plagues squash. It just seems like a good idea, and the squash seem happy enough to climb up the trellis.
I am not a very tool-savvy person and I haven’t dedicated the time to engineering this sort of project. So imagine my excitement to watch squash growing like this on trellises we didn’t have to build.
There is some mildew on the lower leaves, but otherwise the plant seems healthy. Most other squash in the garden were 75% mildew at this point.
I am worried about that the weight of heavier squash might pull them off the vine before they’re fully ripe. So far, I haven’t seen many issues with this at the community garden so it may not be a problem after all. Plants are pretty smart about gravity, so they might know how to handle it. If you’re worried about the weight, you can fashion a little hammock for the squash. The trellis method is more labor-intensive than letting squash grow across the ground, but since Krista & I seem to have an affinity for making gardening projects more labor-intensive than other people (see: our potato stacks) that shouldn’t be a problem.
This method wouldn’t work with very large squash like the hubbards, but I can imagine acorn squash or sugar pie pumpkins getting along fine without ripping down the structure. A major limiting factor for how much squash we plant is always space, so I’m excited about the possibilities. Have you ever grown winter squash vertically? Share your experiences!
