When dealing with tomato plants that grow too tall, a trellis can be a gardener’s best friend. This simple yet effective support structure helps manage the height of the plants, keeping them off the ground and reducing the risk of soil-borne diseases.
Aim to prune plants when the suckers are between 2 and 4 inches long. Determinate tomato plants (those that reach 4 feet tall or so and stop growing) only need to be pruned once. Indeterminate tomatoes can be pruned every couple of weeks as they continue to produce new leaves.
Pinching out new growth is a way to control a tomato plant’s growth. Use your thumb and forefinger to pinch out the growth tip or sucker. Pinch out new growth when it is small, between 2 and 4 inches long. Simply break or pinch the new growth off after flexing it back and forth.
To speed ripening late in the season, remove the growing tip of each main stem about four weeks before the first expected fall frost. Called “topping,” this type of pruning causes the plant to stop flowering and setting new fruit, and instead directs all sugars to the remaining fruit.
When the plant reaches the desired height–usually no taller than its support, 4 or 5 feet is good–consistently pinch out all new growing tips. In a week or so time, the plant will quit trying to put out new growth at the topmost part of the plant and concentrate on new growth and fruit below.
