Why Is My Coleus Wilting and What Should I Do About It?

Wilting is a common problem with Coleus plants. If you notice your Coleus plant wilting, a few things could be causing the problem.

The most common reasons for a wilting Coleus plant include:

1. Lack of Water

One of the most common reasons a Coleus plant wilt is lack of water.

Water is essential for plants because it helps them to absorb nutrients from the soil and stay hydrated.

When the Coleus plant doesn’t have enough water, the plant won’t be able to absorb the nutrients it needs to stay healthy, and the leaves will start to wilt.

How To Tell If Your Coleus Plant Is Wilting Due To A Underwatering

A few signs will help you to know if your Coleus plant is wilting due to lack of water.

In addition to wilting, you may also notice:

  • The leaves of the Coleus plant turn yellow or brown
  • The leaves of the Coleus plant begin to fall off
  • The soil around the Coleus plant is dry and cracked
  • The Coleus plant is drooping
  • The Coleus plant seems stunted or slow-growing

How To Treat A Wilting Coleus Plant Due To Lack Of Water

If you think that your Coleus plant is wilting due to lack of water, the first thing you need to do is water the plant.

Give the Coleus plant a good watering, ensuring that the soil is moistened through.

They must be watered at least once a week but more frequently during hot, dry weather.

Water your Coleus plant in the morning, so the leaves have time to dry off before nightfall.

Once you have watered the Coleus plant, you should see an improvement within a day or two.

If the Coleus plant doesn’t start to improve after being watered, there may be another issue causing the problem.

2. Too Much Water

While lack of water is a common cause of wilting, too much water can cause problems.

When the Coleus plant gets too much water, the roots will start to rot. This can happen if the plant is left in standing water or if the soil around the plant is constantly wet.

If the roots of the Coleus plant are rotting, the plant will not be able to absorb the water and nutrients it needs to stay healthy.

The leaves of the Coleus plant will start to wilt and turn yellow or brown. The plant may also begin to produce fewer leaves.

  • The Coleus plant is drooping
  • The Coleus plant seems stunted or slow-growing

How To Treat A Wilting Coleus Plant Due To Overwatering

If you think your Coleus plant is overwatered, you first need to stop watering the plant.

Allow the soil around the Coleus plant to dry out completely before you water the plant again.

Once the soil is dry, water the Coleus plant, making sure that the soil is moistened all the way through.

They must be watered at least once a week but more frequently during hot, dry weather.

You may also need to check the drainage of the pot or container that the Coleus plant is in.

If the pot does not have adequate drainage, the roots of the Coleus plant will start to rot.

3. Low Humidity

Coleus plants are native to tropical climates and prefer high humidity.

They need a humidity level of at least 50% to stay healthy.

If the humidity level drops below 50%, the Coleus plant will start to wilt.

The leaves of the Coleus plant will turn yellow or brown, and the plant may also produce fewer leaves.

Fill a tray with pebbles and water, and then place the Coleus plant on top of the pebbles.

The water will evaporate and increase the humidity around the plant.

You can also mist the Coleus plant with water a few times a day.

4. Too Much Direct Sunlight

Coleus plants need bright, indirect sunlight to stay healthy.

They should be placed in an area where they will get 4-6 hours of sunlight each day.

If the Coleus plant gets too much direct sunlight, the leaves will wilt and turn yellow or brown.

The plant may also produce fewer leaves.

If the Coleus plant is still wilting, you can try repotting it in fresh soil.

Don’t fertilize the plant again until it has recovered from the wilting.

7. Pest Infestation

Coleus plants can be susceptible to pests, such as aphids, mealybugs, and spider mites.

These pests can suck the sap out of the Coleus plant, causing it to wilt.

Aphids are tiny green or black insects that congregate on the undersides of Coleus leaves.

Mealybugs are tiny white insects that produce a waxy substance. They can be found on the stems and leaves of Coleus plants.

Spider mites are tiny red or brown insects that spin webs on the Coleus plant.

8. Diseases

Coleus plants can be susceptible to diseases such as root rot, downy mildew, and powdery mildew.

These diseases can cause the Coleus plant to wilt.

Root rot is a disease that affects the roots of the Coleus plant. The roots will turn brown or black and may fall off the plant.
