When is the Best Time to Plant Tomato Seeds?”

“When is the best time to plant tomato seeds?” Question from Diana of Indianapolis, Indiana

Answer: This is an easy question to answer! It takes around six to eight weeks to grow tomatoes from seed to ready-to-plant starts. And, tomatoes produce fruit between 65 to 85 days after planting, depending on the variety, so you want to give them plenty of time to produce good fruit through the warmth of summer. It’s also good to know that determinate or bush-type tomatoes produce earlier than indeterminate or vining tomatoes.

I always start my tomatoes indoors for the best results. Then, once the threat of frost has passed, I plant them outdoors. Please read this great Black Gold article Growing Tomatoes from Seed to Harvest. It will tell you everything that you need to know to grow the best tomatoes possible from seed.

Happy tomato growing!
