Updated: April 17, 2022

Citronella plants are a popular choice for people who want to keep mosquitoes away from their gardens, patios, and homes. These plants are easy to care for and they have a lovely lemony scent that makes them a pleasant addition to any outdoor space. However, one of the most common problems that citronella plant owners face is rot. If your citronella plant is starting to rot, don’t worry – there are several things you can do to prevent further damage and save your plant.

Understanding Citronella Plant Rot

Before we dive into the solutions, it’s important to understand what causes citronella plant rot. Citronella plants are susceptible to rot when they are overwatered or when their soil does not drain properly. When the plant’s roots are in standing water for too long, they begin to rot, which can spread throughout the plant and cause irreversible damage.

How to Prevent Citronella Plant Rot

The good news is that preventing citronella plant rot is relatively simple. Here are some things you can do:

1. Choose the Right Pot and Soil

Make sure you choose a pot that has drainage holes and is large enough for your citronella plant’s roots to grow. The soil should be well-draining, so look for a potting mix that contains perlite or vermiculite. Avoid using heavy soils like clay or garden soil, as they can retain too much moisture.

2. Water Your Plant Correctly

Citronella plants like moist soil, but they don’t like to sit in standing water. Water your plant deeply once a week, and make sure the excess water drains out of the pot’s drainage holes. If you’re not sure when to water your plant, stick your finger about an inch into the soil – if it feels dry, it’s time to water.

3. Provide Adequate Sunlight

Citronella plants need at least six hours of sunlight a day to thrive. Make sure your plant is in a spot that gets plenty of sunlight, but also provides some shade during the hottest part of the day.

4. Prune Your Plant

Regular pruning can help prevent citronella plant rot. Remove any dead or yellowing leaves, as well as any stems that look weak or damaged. This will help keep your plant healthy and prevent any rot from spreading.

5. Use Fertilizer Sparingly

Citronella plants don’t need a lot of fertilizer to grow, so use it sparingly. Too much fertilizer can actually harm your plant and make it more susceptible to rot. Use a slow-release fertilizer once every few months, or use a liquid fertilizer at half strength once a month.

What to Do if Your Citronella Plant is Rotting

If you’ve noticed that your citronella plant is starting to rot, there are a few things you can do to save it:

  1. Remove any dead or rotting leaves, as well as any stems that look weak or damaged.
  2. Repot your plant into fresh soil that is well-draining.
  3. Water your plant less frequently – let the soil dry out slightly between waterings.
  4. Move your plant to a spot that gets more sunlight and better air circulation.

If your plant is severely rotted, it may be too late to save it. In this case, you’ll need to dispose of the plant and start fresh with a new one.


Can I plant citronella plants in the ground?

Yes, you can plant citronella plants in the ground as long as the soil is well-draining. Make sure the area gets at least six hours of sunlight a day and water your plant deeply once a week.

Can I use citronella plants indoors?

Yes, you can use citronella plants indoors as long as they get enough sunlight and are not overwatered. Make sure your pot has drainage holes and use a well-draining potting mix.

Do citronella plants actually repel mosquitoes?

Yes, citronella plants contain citronella oil, which is a natural mosquito repellent. However, the concentration of citronella in the plant may not be strong enough to repel all mosquitoes. It’s best to use citronella candles or sprays in addition to the plant for maximum effectiveness.

In conclusion, preventing citronella plant rot is all about proper care and maintenance. By choosing the right pot and soil, watering correctly, providing adequate sunlight, pruning regularly, and using fertilizer sparingly, you can keep your plant healthy and thriving. If your plant does start to rot, take action quickly to save it before it’s too late. With a little bit of effort, you can enjoy the benefits of this lovely plant for years to come.
