Heirloom tomatoes growing
There are two reasons to tie tomatoes, and there's a different tie for each one. Train the leader to grow upright with a loose, figure-eight tie. To support burgeoning fruit, loop a long tie above a fruit cluster, and tie it to the stake 6 to 10 inches higher. Loop the tie twice around the stake and tie it tightly so the tomatoes don't pull it down with their weight.
