This year, for the first time, I am training my tomatoes on tall stakes. This involves frequent pruning of the plants to remove the buds that form at branch nodes, so that the plants grow as one or two long vines, tied to bamboo poles at 10 inch intervals. The process of pruning and tying 120 different plants takes much less time than I imagined it would. In theory, growing plants vertically in this manner will improve air circulation around the plant, to reduce the possibility of the plants developing late blight. I must say, the plants look wonderously healthy so far, so fingers crossed.
