Start seeds indoors 6 to 8 weeks before your last spring frost. Maintain soil temperature between 68 and 82 degrees Fahrenheit for reliable germination. Seeds typically emerge within 5 to 10 days under these conditions.
Transplant seedlings outdoors after the last frost date has passed and soil has warmed to at least 60 degrees Fahrenheit. Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days. Space plants 24 inches apart in rows that are 36 inches apart.
Harvest grape tomatoes when they have fully colored up and feel slightly soft to gentle pressure. For Brad's Atomic Grape, wait until fruits display their vibrant color fully, which indicates peak ripeness and flavor. Pick tomatoes by gently twisting and pulling from the vine, or use pruning shears to avoid damaging the plant. Harvest regularly throughout the growing season to encourage continued fruiting on this indeterminate variety.
As an indeterminate variety, Brad's Atomic Grape will benefit from pruning suckers (shoots that grow between the main stem and branches) to direct energy into fruit production rather than excessive vegetative growth. Remove lower leaves as the plant grows to improve air circulation and reduce disease pressure. Regular pruning helps manage the plant's height and keeps it more manageable for harvesting.
