Here's why your tomatoes may not be ripening and how you can get them to ripen faster on the vine!
Tomatoes won’t turn red if it’s too hot (above 85°F, or 29.4°C) or too cold (below 50°F, or 10°C ). This is probably the biggest culprit for most people, especially during a heatwave.
When that happens, they tend to spend most of their energy on producing leaves and flowers, rather than ripening tomatoes.
When your tomato plant is covered with small, immature fruits, they can steal energy away from ripening the mature ones.
Topping the plant and cutting off all the new foliage will give it more energy to ripen tomatoes faster.
This late in the season, it’s a pretty sure bet that new flowers aren’t going to amount to anything. So pick off all the flowers.
Suckers are the smaller stems that form between a branches and leaf joint. They get their name because they suck energy from the plant.
I know it’s hard to remove any tomatoes from the plant, but these poor little babies won’t have time to mature before frost.
Don’t cut off all of the leaves. But if your plant is huge and full of healthy green leaves, you can trim off much of that vigorous growth.
