Can I cut back sugar snap peas?
One lesson now learnt: don’t wait until the sugar snap peas grow to the top of the frame before tip-pruning them. The result is that they keep growing, and keep growing, and then fall over. My approach for next year: start tip-pruning the sugar snap peas when they get half way up the frame.
How tall should a sugar snap pea trellis be?
Simply zig-zag the panels through your row of peas and push them into the ground (add a stake on each end in windy locations). Total length 9’8″ by 37″ high installed. For more height, choose the Tall Expandable Pea Trellis, which is 64″ high installed.
How high do sugar snap peas grow?
Peas (Pisum sativum) are an easy and satisfying garden plant to grow, but annual sugar snap peas (Pisum sativum var. macrocarpon) really like to grow and can top 8 feet in height. The Missouri Botanical Garden recommends staking sugar snap peas or growing them on a trellis.

Sugar snap peas are like snow peas in that we eat the entire pod. A difference is that the pods of snow peas are flat and those of sugar snap peas are round. Unlike beans, peas do not open when they are ripe or have a membrane in the pod. Most cultivars are climbing vines and need a trellis for support (Fig.
Can pea plants be pruned?
In fact, since pruning forces the vines to branch, you might get more peas than ever. But there is some risk, because pruning sets back growth and delays flowering. If the weather turns hot before the vines reach full size, you could end up with a smaller crop or no crop at all.
How tall should a trellis be?
So, how tall should a trellis be? A trellis that is 6 feet tall will allow adequate climbing height for most plants, while still allowing you to harvest most of the crop easily. If you want to provide more than 6 feet of growing height for plants, you may want to use a lean-to, A-frame, or arch trellis for support.
Do snap peas climb?
Climbing varieties can reach six to eight feet in height and should be trellised. Since the pea tendrils will wrap around supports about 1/4-inch in diameter, add twine, string, small wire mesh or netting to the trellis to help them climb.
