Pot-tomato Heartbreaker F1 has delicious heart-shaped snack tomatoes and is one of its kind. Sow in seed trays and as soon as they can be handled, prick out in pots or soil blocks. Later transplant to a greenhouse or outside to a warm, sheltered spot. Do NOT pinch out the top of Heartbreakers and do NOT remove the offshoots in the axils of the leaves. Ater transplanting, let the plant grow and harvest only the fruits when ready. After some time fertilize with tomato feed.
