30+ ORGANICALLY GROWN Paul Robeson Tomato Seeds, Heirloom NON-GMO, Low Acid, Indeterminate, Open-Pollinated, Rich Flavor, From USA ORGANICALLY GROWN Paul Robeson Tomato Seeds, Heirloom NON-GMO, Low Acid, Indeterminate, Open-Pollinated, Rich Flavor. 80-90 days. Keep moist, not letting the seeds dry out between watering. **SOIL Temperature for Germination: 70-75F. Planting Depth: 1/4". Sprout tomato seeds in small containers, preferably 4" or smaller. In-ground germination is not recommended. Use a standard potting mix that is well drained. Start seeds in containers approximately 8 weeks prior to the planned set-out date. Plants should ultimately be transplanted to the garden 1-2 weeks after the expected date of last frost. Soil should be kept consistently warm, from 70-85F. Cool soils, below about 60-65F, even just at night, will significantly delay or inhibit germination. Additionally, overly warm soils, well above 90F, can inhibit germination and provide ideal conditions for seed rot. Over watering can cause fungal growth which leads to seed rot. Excess water can also bury seeds deep in the soil where they will not be able break the surface. Water when the soil surface just begins to dry. Multiple seeds can be planted in a single starter container, but should be thinned once seedlings appear so only a single plant remains. Seeds do not require light for germination but some light source should be provided for seedlings once they emerge from the soil.
