we only plant indeterminate heirlooms.
We place each plant in a hole that has one tbs.of epsom salts, and one handful of a worm casting/bone meal mix into the hole, throw a little dirt over the mix, and water in the plant.
As far as removing the leafs, this is wrong, the plant need the leaves for photosynthesis, and cutting them back can drastically effect the production, AND, expose your tomatoes to the sun, causing sunscald.
Now as for pruning the suckers, or side shoots, some remove the whole sucker, Others, most typically the busy gardener who has gotten behind, do what is called a "Missouri Prune" I have included a graphic to show both.
I let the suckers get a bit long, then do th Missouri prune, this makes for MORE leaves, thereby more photosynthesis.
we plant 45 tomatoes every year, and the last 4 years average is 75-100 pounds every three days.
must be doing something right
