I have seven tomato plants - two different varieties, three purple heirloom (Cherokee) and four yellow pears. I bought them from a local farm and have had great luck with their products before. For the first two weeks, they were in great shape - but for the past two or three weeks, they haven't grown at all! I expected to have large growth spurt since we have had plenty of rain and nice sunny days ... but nada! I know that I have them planted too close - but I didn't think that would effect their growth. Should I remove some of the plants or is there something else going on? I am including some images! Thank you!!!
