How to Save a Dying Cuphea Plant

Updated: May 1, 2022

Cuphea plants are popular for their bright and colorful flowers that bloom throughout the year. However, like any other plant, they can become sickly and die if not properly taken care of. If you have a dying Cuphea plant, don’t worry, there is still hope. Here are some tips on how to save your dying Cuphea plant.

Identify the Problem

The first step in saving a dying Cuphea plant is to identify the problem. There are several reasons why your Cuphea plant may be dying, including:

  • Overwatering
  • Underwatering
  • Poor soil quality
  • Lack of sunlight
  • Pests or diseases

Once you have identified the problem, you can take steps to correct it.

Correct Watering

One of the most common reasons for a dying Cuphea plant is over or underwatering. To check if your plant is overwatered, look for yellowing leaves and mushy roots. If your plant is underwatered, the leaves will turn brown and start to wilt.

To fix overwatering, allow the soil to dry out completely before watering again. To fix underwatering, water your Cuphea plant regularly and make sure the soil doesn’t dry out completely.

Soil Quality

Cuphea plants prefer well-draining soil that is rich in organic matter. If your Cuphea plant is in poor quality soil, it may struggle to grow and eventually die.

To improve soil quality, add organic matter such as compost or aged manure to the soil. This will help retain moisture and provide nutrients for your plant.


Cuphea plants require at least six hours of sunlight each day to grow properly. If your plant isn’t getting enough sunlight, it may become weak and susceptible to disease.

To fix this problem, move your Cuphea plant to a sunnier location or provide it with artificial light if necessary.

Pests and Diseases

Pests and diseases can also cause a Cuphea plant to die. Common pests include aphids, spider mites, and whiteflies. Diseases such as root rot and powdery mildew can also be a problem.

To prevent pests and diseases, keep your Cuphea plant healthy by providing it with proper watering and sunlight. If you notice pests or diseases, treat them immediately with an insecticide or fungicide.


Can I save a Cuphea plant that has lost most of its leaves?

Yes, you can save a Cuphea plant that has lost most of its leaves. Follow the steps above to identify the problem and correct it. The plant may take some time to recover, but with proper care, it should start to grow new leaves.

What kind of fertilizer should I use for my Cuphea plant?

Cuphea plants prefer a balanced fertilizer that is high in nitrogen. You can use a slow-release granular fertilizer or a liquid fertilizer every two weeks during the growing season.

Can I propagate my Cuphea plant?

Yes, you can propagate your Cuphea plant by taking cuttings from the stem. Make sure the stem is healthy and has several leaves. Dip the stem in rooting hormone and plant it in well-draining soil. Keep the soil moist and provide the cutting with bright, indirect light until it roots.

Saving a dying Cuphea plant takes time and effort, but with proper care, you can bring your plant back to life. Identify the problem, correct it, and provide your Cuphea plant with the proper care it needs to thrive.
