Indigo Rose Tomato

Start seeds indoors 6-8 weeks before the last expected frost, planting 1/4 inch deep in quality seed-starting mix. Maintain soil temperature between 70-90°F for optimal germination, which typically occurs within 7-14 days. Keep soil moist but not soggy, and provide strong light or grow lights positioned a few inches above seedlings to prevent legginess.

Begin hardening off plants 1-2 weeks before transplanting by gradually exposing them to outdoor conditions, starting with 1-2 hours daily in partial shade. Transplant after all frost danger has passed, burying plants up to their first set of true leaves to encourage strong root development. Space plants 24 inches apart in sunny locations with well-amended soil.

Harvest when fruits transform from their initial glossy black color to deep purple-red, with the characteristic red coloring developing on the bottom while the sun-exposed portions maintain their dark purple hue. Pick fruits gently by twisting them off the stem or using clean pruners. The 1-2 ounce tomatoes are ready typically 75-80 days from transplant, and should be harvested when fully ripe for the best plummy flavor development.

While not strictly necessary due to their compact nature, removing lower leaves helps prevent soil-borne diseases and improves air circulation. Pinching out suckers that grow between the main stem and branches can encourage better fruit production, though this indeterminate variety is naturally more manageable than traditional sprawling types.
