Yes, I spray the tops and bottoms. The best thing for the ground as well as your plants, is to make sure you have good soil with nutrients.Thank you for your response. It looks as though my three squash plants are not doing so great (I never got around to spraying them with your concoction, as they turned for the worse right after you sent it.) I used a razor blade looking for squash borer yesterday, but the stem "seemed" to be healthy. Have you been successful with winter (butternut) squash?
I have really never tried it. I have grown acorn squash, zuchinni, and summer squash. I like the acorn squash, because it tastes kinda like sweet potatoes.
The other two are kinda bland, so they make a good filler with other stuff, I guess, but the texture is not to my likeing either.
