Some CalCarb for the Pumpkin Plants Today

I gave both of my plants some CalCarb this evening. CalCarb is a micronized calcium product that you spray foliar on the leaves. The idea is that as the calcium breaks down it produces carbon dioxide which helps with photosynthesis. The other thing that it does is change the structure of the leaf slightly which seems to help with heat stress. We have some warm days coming up in Denver so I usually like to try to put some CalCarb on the leaves about every two weeks, particularly prior to a heat wave.
