Planting & Care

Start seeds indoors 6-8 weeks before the last frost date. Sow seeds 1/4 inch deep in seed-starting mix, keeping the medium consistently moist but not waterlogged. Provide bottom heat to maintain soil temperature around 75°F for best germination, which typically occurs in 7-14 days. Once seedlings have two sets of true leaves, transplant them into larger pots and gradually acclimate them to outdoor conditions before planting in the garden after the danger of frost has passed.

Provide sturdy support such as stakes or cages for the indeterminate vines. Water regularly, aiming for about 1-2 inches per week, and mulch to retain moisture and prevent soil splash. Fertilize with a balanced fertilizer according to package instructions. Prune suckers to encourage larger fruit and better airflow, and harvest fruits when they are fully colored and slightly soft to the touch.
