SOWING:
Start your Big Rainbow tomato plants indoors 6-8 weeks before your last frost. Plant your tomato seeds 1/4" deep in your seed starting tray flats, cells or peat pots. Keep the temperature at 70-75 degrees F until germination. Be sure to provide adequate lighting for germination and for growing by placing the growing trays near a sunny window or using a grow light. As your seedlings begin to grow you will consequently need to transplant them into individual pots to grow more strongly rooted plants.
A week before transplanting the seedlings outside you need to begin to harden off the plants. They need to get used to the outside weather gradually. Tomatoes cannot handle cold weather. To be safe wait at least a week or two after the final frost to be on the safe side before transplanting your tomato plants in the vegetable garden. Soil temperature should be at least 70 degrees F before planting. Your Big Rainbow tomato plants should also be planted in full sun, very rich soil and be spaced 24" apart with about 36" between rows.
