Planting Instructions for Siberian Tomato Seeds
Start Siberian Tomato seeds indoors 6-8 weeks before last frost date. Plant the Tomato seeds ¼” deep in sterile seed starting mix. Germination occurs in 6-14 days in soil 70-90°F. Once true leaves develop, separate Heirloom / Open Pollinated Tomato plants into 3-4″ pots, placing in full light & cooler temps (60-70°F). Set out hardened off Tomato transplants, in full sun, once soil has warmed, 18-30″ apart, in rows 3-4′ apart. Plant tall, spindly Tomato seedlings deeper, the stems will sprout roots and support and strengthen the plant. To help prevent blossom end rot, put 1 Tbs of lime, ground oyster shells, or crushed eggshells at the bottom of your planting hole. The calcium will help build strong cell walls once your heirloom tomatoes plants start producing fruit. For strong tomato plants, add 1 Tbs of aged compost and 1 Tbs of bone meal to the bottom of the hole as well.
