If you haven’t plant your tomato seeds yet, don’t bother. To produce lots of ripe fruits these seedlings need the extra long season and early warm days that only extra lights and indoor warmth will give them. They can be started in a heated greenhouse between March and April depending of where you live. May is a good month to start hardening your seedling by placing them outside during the days and back in for the nights. They will be ready to plant in large pot or directly in the garden after the last risk of frost, which is usually around mothers’ day,
Next time you visit a farmers’ market and see a vendor that sell hand-picked varieties of tough starter plants don’t hesitate to spend a few buck. These plants and a bit of loving care will yield you such a crop you won’t regret the investment.
