Black Krim Tomato

Start seeds indoors 6-8 weeks before the last expected frost date, sowing 1/4 inch deep in seed starting mix. Maintain soil temperature between 75-85°F for optimal germination, which typically occurs in 7-14 days. Keep soil moist but not soggy during germination, then transplant seedlings to individual 4-inch pots once they develop their first true leaves.

Transplant outdoors when nighttime temperatures consistently stay above 55°F and soil has warmed. Plant deeply, burying the stem up to the lowest set of leaves to encourage adventitious root formation. Harden off seedlings gradually for one week before transplanting to help them adjust to outdoor conditions.

Harvest Black Krim tomatoes when they display their characteristic dark red-purple skin color with green shoulders and reach 4-5 inches in diameter. The fruits will feel slightly soft when gently squeezed and may have unique rounded or slightly flattened beefsteak shapes. For best flavor, allow fruits to ripen fully on the vine before picking, then harvest by gently twisting or cutting from the vine. The indeterminate nature allows for continuous harvesting throughout the growing season.

As an indeterminate variety, Black Krim benefits from regular pruning to improve air circulation and direct energy to fruit production. Remove suckers that form in the crotch between main stems and horizontal branches, and prune lower leaves regularly. Some growers prefer to let the plants grow naturally, but pruning typically results in better air circulation and easier harvest access.
