Pest And Disease Management

Martha Washington geraniums are beautiful and colorful plants that are relatively easy to care for. However, they are prone to certain pests and diseases.

Proper pest and disease management is crucial to ensure your plants grow healthy and strong and produce stunning blooms.

Here are some essential tips on how to manage pests and diseases when caring for Martha Washington Geraniums.

Common Pests

Martha Washington geraniums are susceptible to common pests such as aphids, spider mites, and whiteflies. These pests can easily attack your plants, causing damage and stunting growth.

Here are some handy tips on how to manage these pests:

  • Aphids are tiny, green-colored insects that feed on the sap from your geraniums. You can wash them off with a strong jet of water or use insecticidal soap.
  • Spider mites are tiny arachnids that can cause a fine webbing to appear on your plant’s foliage. Use a miticide to control this pest.
  • Whiteflies are tiny, white-colored insects that can cause leaves to turn yellow and fall off. Use yellow sticky traps or install a vacuum cleaner to keep them away.

Disease Management

Martha Washington geraniums can also be affected by various diseases such as stem rot, leaf spot, and powdery mildew.

These diseases can quickly spread from plant to plant, leading to significant damage. Here is how to manage them:

  • Stem rot is caused by overwatering and poor drainage. To manage it, ensure proper drainage and reduce watering frequency.
  • Leaf spot is caused by water splashing on the leaves and soil-borne fungal spores. Remove infected leaves immediately to prevent further spread.
  • Powdery mildew is caused by humidity and moisture. To manage it, increase ventilation and reduce humidity levels.

Winter Care Tips

The winter months can be harsh on your geraniums, especially if they are Martha Washington geraniums. Keeping them healthy and vibrant takes a bit of extra care and attention.

Here are some tips on how to care for your geraniums during the winter months.

Keep Them Warm

Martha Washington geraniums do not tolerate extreme cold, so ensure they are in a warm place.

Keep them away from windows and drafty doors or cover them with a light cloth if situated in an area with low temperature. They prefer temperatures between 60–70°f (15–21°c).

Water Them Carefully

During the winter months, watering your geraniums excessively can result in root rot. It is best to water them as sparingly as possible.

Before watering, check the soil moisture level and water only if it feels dry one inch below the surface.

Use room temperature water to avoid shocking the roots.


Since geraniums can be susceptible to pest invasions during winter, it is a good idea to use organic pesticide to repel mites and other insects.

Avoid using chemical pesticides or fertilizers during this season as it can damage the plants.


Although geraniums prefer sunlight, during winter, they require less light than they do in the summer months. Ensure you place them under bright, but indirect sunlight.

If the natural light is low, you can make use of appropriate fluorescent lighting to supplement their light intake.

Prune Regularly

Prune regularly to give your geraniums room to breathe, cut back leggy stems, and remove any dead or dying flowers or leaves. This allows for new growth during sprouting season.

Reduce Fertilization

Your geraniums will go dormant in winter, so it is best to reduce the frequency of nitrogen-rich fertilizers to once every two months.


It is okay to re-pot your geraniums in winter. Inspect the root-ball for any signs of root-bound and transfer it to a pot with ample drainage.
