Brad's Atomic Grape Tomato

Start seeds indoors 6-8 weeks before your last spring frost date. Keep soil temperature between 68-82°F for reliable germination, maintaining consistent moisture until seedlings emerge. Provide bright light once sprouted to prevent leggy growth.

Harden off seedlings gradually over 7-10 days before moving them to the garden. Transplant outdoors after the last frost date when soil has warmed to at least 60°F. Space plants 24 inches apart with 36 inches between rows.

Pick fruit when it develops those distinctive olive-green, red, and blue-brown striping and yields slightly to gentle pressure. The color transformation from purple-lavender to the full Technicolor palette is your main visual cue for ripeness. These tomatoes hold exceptionally well on the vine, allowing you to harvest at peak ripeness without fear of sudden drops. For peak flavor, harvest when fully colored and allow to sit at room temperature for a day or two if picked slightly early.

As an indeterminate variety, Brad's Atomic Grape will benefit from light sucker removal to direct energy into fruit production rather than excessive vegetative growth. Prune lower leaves once the plant is established and begins flowering to improve air circulation and reduce disease pressure. However, avoid aggressive pruning that removes too much foliage and exposes fruit to sunscald.
