Q.Cracking tomatoes
As my tomatoes almost reach full size they crack from the stem down. I have been keeping the container pots very moist as I read that in the heat the skin become tuff if there is not enough water. They still crack. I plant them early and grown Arkansas Travelor, Celebrity and a German Queen. At my location on the High Desert of Ca the temp
is mostly in the 100’s by mid July. The cracking looks like the pics you seen on the web. Oh the German Queen
cracks in a circular fashion. My potting soil is the Miracle Grow brand with fertilizer in it.
Any ideas———Thanks James
Tomatoes actually tend to crack if they get too much water, so that might be your problem. This article should tell you more:
