I Threw in two yellow squash last year late in an empty 10' sqr area where we'd pulled bolting spinach thinking that would be plenty of room. Wife had some bok Choi planted adjacent. About 3 weeks later you couldn't find the choi.Found same when I planted yellow squash didnt do near as good.I wonder about tomatoes plant same kind and some allways are better and couple allways lot smAller less fruit
Damn things put out about 35 squash in the last 2 months of the season. We've got too crowded as we have so many different plants.
I'm reluctant to expand as it's already a bit overwhelming.
