Wilting tomato plants in pots is characterized by drooping leaves and makes the tomato plant lose its shape. Let us further look into the details of wilting tomatoes in pots. So, here are the common reasons why your tomato plant may be wilting in your containers.

1.    Lack Of Water Or Under-Watering

When your potted tomato plant isn’t watered sufficiently especially during the hot days, it can cause wilting of leaves as well as stems. This wilting can be temporary which causes the leaves and stems to lose water faster than they can replenish it.

Sometimes when this happens, they may recover in the evening and it may not require extra watering. However, if the wilted potted tomato refuses to be revived after the weather cools down in the evening, they will need watering.

2.    Over-Watering

Apart from lack of water in your potted tomato plant, over-watering that leads to soggy plants can cause wilting. When the plant is soaked in excess water, the roots get drowned and cause the plant to be unable to absorb water from the soil. Hence, leading to wilting of the plant.

This is why you need to monitor your potted tomato plant, especially during the rainy season or heavy downpours. Don’t supply excess water during rainy seasons if your potted tomato is outdoors. Or you can simply take your potted tomato plant indoors to avoid over-watering from heavy downpours.

If your potted tomato is suffering from overwatering, then it’s possible for it to recover. Simply cease watering the plant and only water when you notice at least 2 inch soil into the soil is dry.

A quick guide to watering your tomato plant appropriately is to roughly provide 1 inch of water every week.

3.    Drainage Holes

Drainage holes are very crucial when it comes to potted plants generally. If the drainage holes you have for your potted tomatoes aren’t enough, it may cause your plant to get clogged due to the inadequate flow of water whenever you water your plant.

Therefore, make sure you have enough drainage holes in your potted tomato plants to allow an easy flow or passage of water.

4.    Transplanting To Bigger Pots

When you improperly transplant tomato plants into another pot or even into your garden, it may cause shock and damage the root of your plant. Then this can lead to the wilting of your plant.

Ensure you don’t tear or cut the tomato plant roots in the process of transplanting and ensure you don’t over-water them.

Additionally, when you are transitioning your tomato (especially the seedlings) outdoors in a sunny area, use any opaque materials during the hottest periods. This is because your plant will need to readjust to the environment so this will help harden them off.

5.    Type Of Soil Used – Wilting Tomato Plants In Pots

If you’re using loose soil such as sandy soil for your potted tomato, it will require you to water more especially during hot seasons. Sandy soil loses water too quickly so they aren’t so great with water retention.

So, it is ideal you water your potted plant accordingly when using loose soil such as sandy soil.

6.    Soil-borne Disease Caused By Wilting

Fungal diseases that are soil-borne can also cause your potted tomato to wilt. Fusarium and verticillium wilt are the two most common soil-borne diseases that can lead to wilting of tomatoes.

When your tomato plant is infected with these diseases, it begins to wilt especially during the day. Then at night, your tomato plant can recover. The fruits of your tomato plant may even yield fruit, but it usually results in smaller or fewer yields. This wilting can slowly become worse and even lead to the death of the plant.

You can further verify Fusarium and Verticillium infection if you cut the affected stem open. You should see a brown to black discoloration of the vascular system of the stem instead of a healthy stem that only has a shade of green.

The best solution is to burn or discard the infected plant. Then you should plant your tomato in a new container and soil and avoid composting the infected plant.

To further protect your potted tomato from Fusarium and Verticillium, we recommend you go for tomato varieties that are resistant to these diseases.
