So I had a thriving Pumpkin plant. For about a couple of weeks the big leaves in the middle of the plant (so the oldest leaves) started to yellow and get crisply on the edges. We've had 90 to 100 degree heat and it gets direct sunlight most of the day so I figured it was just stressed. We turn the hose on it every day during the heat of the day and soak the ground.
I've got grass clippings covering most of the ground. which is great for keeping most weeds out and keeping the ground from drying out to quickly but I have had to spread a bunch of seven dust to keep controls the bugs that also love the grass clippings. But I haven't spread any seven dust for at least three weeks.
This is about 4 days ago.
One of the long vines shriveled up completely by day 4. The rest of the vines keep growing longer and even have some pumpkins larger than a fist growing on them. But their leaves closest to the center are starting to yellow too.
What's going on and how can I save my pumpkins!!!!!!!!!
