Thanks for your great ideas. Outside of taking a soil sample to our university extension/ag center ...I may just guess what is wrong. I mean, it's not very serious [yet] ....but temps are getting hot & humid....so other things can happen if plants are compromised.
Fortunately, I see no creepy crawlies...only critters are the deer and rabbits......raccoons are watching the corn stalks for their annual attack on the bounty.
Oh boy, here's a new one on me... a couple of months ago we saw that there were some volunteer pumpkin-looking plants popping up in the garden near the compost pile. Now, we could tell that the plants were some member of the gourd family, but whether it was a melon, a cucumber, a pumpkin, a squash, or a good old-fashioned decorative gourd we really had no way of knowing. Figuring it was the typical pie pumpkins we have had in the past, I transplanted them into more appropriate locations, and watched them grow.
Now they've made fruit... and, honestly, I still really don't know what they are. I included the glasses in the photo to give some sense of scale:
They look like a gourd, but also something like a crook-neck squash. I have tried one sliced up raw while it was still tender, and it had the mild flavor and texture of a yellow crook-neck summer squash.
So that's good at least... they're edible. Still, I've never seen a squash that looked like these. Has anyone else?
