My butternut squash leaves suddenly started turning black and curling up. I live in FL; this started about same time as it got real hot - may or may not be related to heat. I sprayed once with Fertiloam Triple Action Plus, but it rained hard the next day. So far, squash on the vine not affected. What should I do?
It's hard to tell, but from the description, it could be an issue with stem blight. This article will help determine if this is the problem: https://www.gardeningknowhow.com/plant-problems/disease/gummy-stem-blight-control.htm
How far apart must you plant spaghetti squash from butternut squash to prevent cross-pollination?
Squash may require as much as 500 feet between varieties to prevent cross-pollination. However, you only need to worry about cross-pollination of squash if you save the seeds for planting next year. Here is an article or two that you may find helpful: https://www.gardeningknowhow.com/edible/vegetables/vgen/cross-pollination.htm, https://www.gardeningknowhow.com/garden-how-to/propagation/seeds/controlling-cross-pollination.htm
I made 4 planters (15" x 5" x 6). I started the seed. Can I plant the containers in the ground and cover them with dirt? Will the squash keep growing down hill? I am talking about butternut.
Thank you,
Joan
I'm not sure what you mean about the squash growing downhill, but the concern with growing a plant like squash in containers is using something large enough to allow room for the roots. I don't know if the containers you describe are large enough. Another consideration is watering. Containers buried in the ground are going to be difficult to monitor, and to water. This article has some other thoughts on growing squash in containers: https://www.gardeningknowhow.com/edible/vegetables/squash/growing-squash-in-containers.htm
I planted butternut & spaghetti squash this year. Spaghetti from packaged seeds & butternut from saved seed. Both are fruiting, but I have also noticed a squash that appears to be coming on the spaghetti squash vines that has a dark green skin with striping that resembles a zucchini but the shape is more like the unripened spaghetti squash. What could have hitchhiked in on my saved seed?
First thing, is it possible you got one of your saved seeds into the spaghetti squash group? Saved seeds often produce plants that are unlike the parent, because the parent was a hybrid plant. However, squashes are all very closely related, so even purchased seeds may produce some unexpected progeny. This article explains more about hybrids and their seeds: https://www.gardeningknowhow.com/garden-how-to/seeds/non-hybrid-seeds-vs-hybrid-seeds.htm
The squash are getting large. Can I leave them on the vine until late September or should I remove when they get to good size?
Here's an article that should help with that: https://www.gardeningknowhow.com/edible/vegetables/squash/butternut-squash-harvest.htm
I would like to save the seeds for the next year, but I don't know if it is possible. If it is, how do I store the seeds?

I've been gardening for a few years, and I've never had this problem. My butternut squash leaves are turning yellow at the bottom of the plant, and they are getting brown spots too. The fruits are growing very nicely. I fertilize the plants once a week and water hasn't been a problem because of the rain we've been getting. What's wrong with my plants?
This is squash end rot, most likely due to the heavy rainfall.
