Pick and Prune for Huge Tomato Harvests

Pick off all flowers until the plant is at least 1-foot tall, that way the plant doesn't devote energy to forming fruit before its roots and foliage have filled out.

Prune all the suckers as they start to grow. Suckers are the sprouts that come up between two main vines. Suckers grow quite long before producing their first flower cluster. By removing them, you allow your plant to use that energy to produce additional flower clusters elsewhere on the plant.
