Its 11:00 in Denver and it is already 93 degrees today with a forecasted high of 99 degrees. Not good pumpkin growing weather. This year's plant seems fine up to about 92 degrees and then after that the heat starts burning up the new leaves. I saw a little of that yesterday on the new leaves on the side vines.
To combat the high temps I've got chairs over the main vine tips to shade them as well as over the pumpkins. At 11:00 and 12:00 I've got the sprinklers set to run for 1 minute and from 1:00-4:00 I've got the sprinkler timer set to mist mode which means it will run every 15 minutes for 20 seconds to cool off the leaves. And then at 5:00 I've got the timer to run the sprinkler again for one minute. That along with the 14% shade from the hail netting will hopefully keep the plants happy today.
I split 1/8 cup of fish & seaweed between both plants yesterday evening. Between that and the warm night last night caused a fair amount of growth before this morning. Seemed like there were new long tendrils everywhere today.
