My tomatoes are very small. The plants look healthy and are about five feet tall.

Question

This is my first garden. The soil is very rich almost black . I’ve kept all the weeds out and watered them when needed. What am I doing wrong?

Answer 1

Did you use a soil that has slow release nitrogen pellets or slow release in any form? This is the most common cause for this. You may have to supplement phosphorus and potassium to offset for the amount of nitrogen in the soil.

There are many "bloom boosters" on the market, and any will work as long as it does not have much nitrogen.
