Growing winter squash in the garden

You may have struggled with squash vine borers destroying your beautiful winter squash before they had a chance to fully ripen. One day the leaves are bright green and pointed towards the sun, and the next day they’re deflated and wilting. Bummer! I say instead of fighting with nature, choose a variety that won’t be bothered by those pests. Enter, black futsu.

This year I did a trial in my garden and planted a black futsu along with a buttercup burgess variety. The only one that made it through squash vine borer season was the black futsu. Plus, it produced six squash from just one plant.

More reasons to love black futsu squash:

Consider growing these for their texture, aesthetics and of course taste. Keep them around for autumn decoration and then devour them for Thanksgiving.

  1. You can eat the skin: The skin of black futsu is totally edible so there’s no need to spend time peeling before cooking.
  2. Easy to grow & productive: This year I harvested six squash from just one plant in the garden. That’s a pretty great ROI per square foot!
  3. Both edible & ornamental: Listen, they’re just the cutest. They’re ready to harvest when the skin turns from shiny to matte and will continue to change colors as they ripen in storage. They’re a gorgeous blend of blue/green/pink/purple/grey.

    This was delicious! I made the lentils in the instant pot with cumin, onion, and garlic powder and I think the dish would’ve been a little bland without that added flavor. The salsa was DELICIOUS!!

    1. Yay! This makes my day. Thank you for your comment and for trying the recipe. Enjoy! – Katie
