Your tomato plants do not grow? How to identify the causes and accelerate growth in tomatoes

Have you already diligently done your gardening plant growing in the spring, but your tomato plants do not grow? The reasons for a poor harvest could be due to various factors that sometimes pose a challenge to amateur gardeners. If you grow tomatoes, you have most likely encountered one or more of these common plant problems. Here is some useful information and advice that can help you take the right action.

Done everything right, and tomato plants won’t grow – What could it be?

tomato plants do not grow optimally when temperatures are too low or too high

If you plant tomatoes in the spring , you may be looking forward to a bountiful crop of fruit at suitable temperatures later. Healthy tomato plants grow quickly under the right conditions, but if the plant doesn’t like one factor, its growth slows or stops. Plants where this happens may be suffering from disease or insect infestation, or they may simply need pruning as well as the appropriate amount of nutrients through fertilizers.

As a rule, tomatoes are not a difficult plant variety to grow. They are really quite hardy and persistent given the right temperature and water conditions. However, the hard part of growing tomatoes is knowing the plant well enough to make it grow the way you want it to. Aside from leaf problems, one of the most common difficulties gardeners have with tomato plants is a lack of fruit. Many who have grown lush, bushy tomato plants wonder: what do tomatoes need to grow?

Why does the plant not form fruit?

flowering tomato plants do not grow properly or do not develop fruit

After you plant your tomatoes in the ground, it usually takes a few months before you can harvest fruit. Each variety of tomato has a different time to fruit formation, which can be 90 days or more. It’s really hard to wait patiently for fruit on your plant, but the first thing you need to do is browse your variety.

This will allow you to estimate approximately when you should expect fruit from that plant. If your tomato plant is definitely old enough to produce tomatoes, then it is time to consider one of these reasons for poor production. There are several causes, but tomatoes grow slowly, so you need to take a closer look at your plant during its growing season.

Prune tomato plant

If your tomato plant has been growing rapidly but has stopped producing flowers and fruit, you may need to prune some of its branches. If you do not prune your tomatoes regularly, the plants will develop extra branches called suckers. These branches are called suckers because they take away the energy the plant needs to produce and ripen fruit.

weeds and lack of nutrients in the soil can affect tomatoes


Look for suckers growing in the crotch between two established branches. To remove a sucker, squeeze the base with your fingers and wiggle back and forth until it breaks off. If your plant is mature and very large, you can also remove larger side stems that are not bearing flowers or fruit. This allows the plant to focus more energy on fruit development.

Well watered, but tomato plants do not grow

regular watering of tomatoes in the garden and avoid overwatering

You should make sure that you water not too much and not too little, but just right. When your plants have periods of drought and flooding, they often respond by dropping flowers. It’s best to water evenly and avoid extreme changes that can cause problems with growth and tomato fruit.

over watering tomatoes do not grow further

If possible, install a drip irrigation system at the base of your plants and water the soil only when the top layer of soil is dry. Depending on your environment, you may need to water every day or only once a week.

Tomatoes do not continue to grow due to lack of nutrients

spread compost around the stem of a tomato plant

Tomato plants, of course, also need nutrient-rich soil to thrive. If the soil is low in nutrients, the plant will suffer from many problems, including stunted or slowed growth. In addition, an unhealthy tomato plant is also more likely to attract pests and diseases. The fruits of a stunted plant will also remain small and take longer to ripen.

pour fertilizer into the soil around a tomato plant and provide the plant with nutrients

To remedy this problem, surround each tomato plant with a layer of aged compost when you grow it. When tomatoes reach golf ball size, fertilize each plant with 1 tablespoon of 10-10-10 fertilizer or ammonium nitrate. Repeat the application three and six weeks later. However, do not allow fertilizer to get on the plant’s leaves when fertilizing. After fertilizing, you should also water the plant well.

Take the right measures against plant diseases and pests.

plant diseases or pests attack tomatoes and cause rots and poor harvests

Even if you prune and fertilize your tomato plant properly, pests and diseases can strike and cause serious problems. When the plant is attacked by a pest or plant disease, it has to expend its energy to fight off the problem. This reduces the energy it needs to continue growing. Diseases that commonly affect tomatoes include root rot, blossom end rot, fusarium, crown rot and wilt, cucumber mosaic virus and bacterial canker. Common pests include aphids, worms, flea beetles, psyllids and stink bugs. To find out how best to treat your plant, search for the suspected pest or disease in a pest database.

tomatoes attacked by insects and other pests in the garden grow slowly or die off

Either your tomato plants will tolerate the disease and grow through it, or they will succumb to the stress and die. Any treatment you apply is really to prevent the spread of infection to other plants, although this is often a futile effort. A heavy infestation of pests such as aphids or spider mites can put additional stress on a tomato plant, which can affect fruit set. How you perform pest control on your plants should be a personal decision.

Ensure optimal temperatures

growing tomatoes in the garden bed by hobby gardeners often leads to mistakes

Tomatoes prefer mild weather, and temperatures that are too low or too high can stunt growth. For example, tomatoes stop setting fruit when the daytime temperature exceeds about 32 ° C, although nighttime temperatures above 20 ° C could also cause problems. In general, temperatures below 15 ° C inhibit growth. When it is too hot or too cold, plants focus on survival, not new growth.

harvest large and ripe tomatoes and take healthy vitamins in summer

With the exception of weather and disease, it is possible that you can use these tips to redirect your plant’s growth to encourage more fruit set. If you are new to gardening, going through this list will help you observe your plant and respond as needed. Experience really is the best path to success in growing tomatoes. Even if you didn’t get a great crop this year, try again next year and the year after.
