When greenhouses open up, I buy my tiny tomato plants and transplant them into larger containers like cottage cheese size. They get a good start in the sun room until I transplant outside after frost. I pinch off the lower branches & lay the plant down in a trench, bury all but the top 3-4 inches. Makes for good root system. This year, instead of using a row for lettuce & spinach, I will tuck a few seeds around other things and keep replanting as we use it. I love Spring !
