The pumpkins have been in the ground 1 month now. We had one small shower the day after I planted and then 3 weeks of no rain and 100+ temperatures. I had to hand water the plants for that period of drought. The last week we have been getting quite a bit of rain. The plants survived and now look to be thriving.
I am afraid of mildew with all the wet weather we are having. I plan to spray a fungicide in the next couple of days to hopefully keep them from getting sick.
In the picture you will notice that some of the plants are much larger than others. In the initial planting, I had some skips and had to go back and replant some spots. I think the younger plants will catch up fairly soon.
