Should tomato plants be pruned?

  • Determinate varieties stop growing at a certain height, have a bushier habit, and produce fruit earlier but in a specific timeframe. These should only receive minimal pruning.
  • Indeterminate varieties, on the other hand, will continue growing and producing fruit until frost. Because of their indefinite growth, they can be pruned rather vigorously.

Pruning tomato plants helps them produce earlier in the season. Tomatoes can be stronger, bigger, and healthier. When tomato plants are both pruned and staked, their chances of contracting diseases are reduced because leaves and stems stay drier and allow for more circulation.

I was heartbroken and figured that was the end of my tomato plant. Still, I placed it in a safer spot and cut off all the broken and damaged stems.

Improved airflow and less disease

With fewer leaves, pruned plants are less dense, allowing more air to move through the plants. The leaves dry faster after a rain, so they are less susceptible to the diseases that need prolonged moisture to develop — something that can be very helpful in wet climates.

Bigger fruit

Pruning at the right time directs energy toward creating and ripening fruit instead of making more leaves. Overall, you will probably have fewer fruit on a pruned plant, but it will be bigger.

Earlier ripening

When a plant's leaves and physiology have fewer fruit to take care of, that fruit ripens faster. This can really help in short season climates, where getting a tomato harvest is often a race against time, thanks to early fall frosts.

There can be various reasons behind the curling of tomato leaves. One reason is insufficient moisture but since you say you're watering them, you'll have to look to other possible reasons. Things to consider are: Herbicides––if sprayed around the area recently, these can cause curling leaves, even if the herbicide drifts on the wind; exposure to wind––too much constant wind can result in curling leaves as they dry out fast; insect infestations, such as broad mites, can cause the leaves to curl; and the tomato leaf curl virus can cause leaves to curl, in which case the plants need to be removed and destroyed to prevent spread of the virus. For insects and viral problems, do some additional research to see if these are the issue for your tomato plants.
