Help diagnose dying or withering vines
These are Big Max giant pumpkins. I planted them late (June 1). I have 4 plants. 2 have pumpkins growing and two look like this. One vine, not long yet, and leaves near the base are dying off. This vine has started a pumpkin twice and thought it was set but they shriveled.
I see no evidence of squash vine borers. I spray BT every week and injected BT early on when the trunks got thick.
I’m wondering if I’m not watering enough? I wanted twice a day (sunrise and sunset). Should I bump that up? Can these be over watered?
I’ve got a few jack-o’-lantern plants also and they’re doing pretty well, though I’m noticing thinning of the leaves around the trunk but the leaves on the vines are nice and green and the vines are long. No pumpkins on those yet.
Appreciate any advice.
