What do you mean "stopped maturing?" Sometimes it seems like forever for them to turn red.

Agree with Ed. Folks expect their fruit to ripen in 1/2 the time it actually takes - 55-65 days - if ripening is what you mean. If referring to the size of the fruit then that is primarily genetics of the variety.

So you need to be more specific about what you mean.

Smaller tomatoes generally mature faster than big tomatoes. Some tomatoes will mature faster than other tomatoes of the same size, because of genetics.

It is hard to gauge what tomatoes are actually doing, while they are green. Are they growing or standing still? They seem to grow slowly. Then BOOM, in just a few days they will develop a hint of yellow, go orange and turn red. It often happens without ANY warning.

Thank you for your responses. Theplants slowed their growth. The tomatoes stopped growing or turning red. My neighbor across the street gave me some of his. Many varities and different ages. I cant help but think the compost tea had something to do with it. Could I have made it too strong? I put about 36 oz. To about 3.25 gal water.

I wish I could tell you about your compost tea, but I don't use it. I compost frequently, and have gradually turned my sandy clay soil into dark loamy soil, with compost, but I only use standard fertilizers.

I will say that I did reach a point where I used neither compost nor fertilizer for a few years, since I think I had too much. Now i use small amounts of regular fertilizer, but only up until June 1st, each year.
