Growing Info

Harvesting: Harvest when the squash's rind is hard enough that you can't dent it with your fingernail and before first frost. Cut stem, (don't break it off) leaving 2" of stem attached, which keeps the squash whole, leaving no opening for infection. Though fruits are hard and may seem indestructible, treat them gently; bruising can spoil squash.

    I planted 3 squash seeds. They went crazy, over the trellis, over the 6' garden fence, and well into the yard. I ended up harvesting 54 squash. :)

    I’ve never been good at growing squash. I’ve tried over the past two years, and I haven’t been ever able to successfully even get a flower on my squash.This year was different though, when I tried to grow the butternut squash, it actually worked really well and a squash is developing on my plant.

    All seeds germinate with vigor except of course shiso, which I always have trouble with.
