Sow seeds indoors (do not direct sow into the garden), using sterile seed starting mix, 6 to 8 weeks before your last expected frost date. Plant 1/4" deep, water lightly but keep moist until emergence.
Full light and cooler temps (60° to 70°) will help to prevent the seedlings from becoming too leggy. If plants become rootbound before you can safely set them into the ground, transplant them into larger pots.
Harden off plants before planting outside. Young plants are very susceptible to frost and sunburn damage. Avoid too much nitrogen. Water evenly but not in excess.

★★★★☆ Great for green tomato recipes

Easy to germinate with strong seedlings. We had a rough year for watering last year, but 'Improved Colossal Yellow' held out nicely and gave lots of small fruit. It seems susceptible to dropping fruit before full ripeness, but my green tomato pie recipe and I didn't mind one bit!
