I'm trying to avoid repeating mistakes of the last growing season. I had a number of cherry tomato varieties I was experimenting with in a south facing, mostly sunny yard (about 2 hrs of shade in mid afternoon from a tree on the south side). I had 4 tomato plants, which all grew about 7-8' high, as I kept them trimmed to a single stalk by trimming the suckers off. The plants produced 100s of tomatoes, but only a handful of them ripened. The fruit kept growing bigger and bigger right through late September, but stayed green right until the plants died off. Is the lack of full afternoon sun preventing the ripening? It seemed odd to me considering how well the plants grew otherwise.
