So, why are my Citronella leaves turning yellow?
There could be several reasons for it, ranging from overwatering or underwatering to pest infestations, diseases, nutrient deficiencies, cold exposure, compacted roots, or simply natural aging.
Let’s dive into each cause then we’ll help you save your beloved Citronella.
Overwatering your Citronella is one of the most common reasons for yellowing leaves.
The reason behind this is simple—waterlogged roots can lead to root rot and restrict oxygen flow to the roots.
Your plant is, in effect, drowning in all the water.
On the other hand, yellowing leaves in Citronella plants can also result from insufficient moisture levels in the soil. Thus, your plant cannot absorb the water it needs to grow properly, leading to stress and the yellowing of leaves in Citronella.
Balancing too much and too little watering is essential to keep your Citronella healthy and green.
You may need to adjust your watering schedule, especially during drier or wetter months.
If the yellow leaves persist, it may signify deeper root damage.
Here are some tips for you:
- Reduce watering frequency—cut back on watering your Citronella plants and only water them when the top inch of soil is dry to the touch.
- Adjust your watering schedule—make sure to water your plants early in the day to allow time for the soil to dry out before evening, preventing the development of fungal diseases.
- Improve soil drainage—if the soil is heavy and poorly draining, consider adding organic matter to improve the soil structure.
- Remove yellow leaves—prune off any yellow leaves to allow the plant to focus its energy on healthy growth.
Now, let’s look at the other causes.
Aphids, spider mites, and whiteflies are common pests that can cause yellowing leaves in your Citronella due to their feeding habits.
Fungal diseases such as powdery mildew and leaf spot can also cause the same.
To prevent pests and diseases, make sure to regularly inspect your plants for signs of infestations and treat them as needed.
If you suspect pests or diseases are causing the yellowing leaves, take action to control them.
I’ll give you some tips to control pests and diseases.
- Remove infected leaves—prune off any infected leaves to prevent the spread of pests or diseases to healthy parts of the plant.
- Control pests—use a pesticide or natural remedy such as neem oil to control pests on your plants.
- Control diseases—use a fungicide to control diseases on your plants, or consider using a natural remedy such as copper fungicide.
Whenever using a fungicide or an insecticide, take the time to read the instructions mentioned in the labeling.
A Citronella plant not getting enough essential nutrients can also result in yellowing leaves.
Remember that your Citronella’s soil will slowly lose its nutrients over time.
If you think that the yellowing of the leaves is due to a lack of nutrients, regular fertilization can help revive your plants.
Here are some tips:
- Fertilize regularly—use a balanced fertilizer to provide your Citronella plants with the nutrients they need to grow healthy and strong.
- Provide proper nutrients—consider using a fertilizer specifically formulated for Citronella plants to ensure you provide them with all the necessary nutrients.
- Prevent overfertilization—too much fertilizer can harm your plants and cause damage. Remember to measure correctly and give your plants the right amount of love and nutrition they need to thrive.
Now, let’s move to the next one.
Citronella plants are tropical plants and prefer warm temperatures. If they are exposed to cold temperatures, this can cause the leaves to turn yellow.
Protect your plants from cold drafts and frost to prevent exposure to cold.
You can move them to a warmer corner in your house or garden or cover them with a protective barrier such as frost cloth.
However, you don’t need to worry if you think you’ve been a little late.
Consider the steps below if your Citronella has just gone through a cold spell or frost.
- Find a better location—a spot that is protected from the cold wind and provides the plant with plenty of indirect light.
- Wait for new growth—this may take several weeks or even months, depending on the severity of the damage.
- Gradually acclimate your Citronella to outdoor conditions—if the weather has improved, you can slowly start introducing your plant to outdoor conditions. Start by placing it in a shaded area for a few hours a day, and gradually increase the amount of time it spends outside until it can handle the full sun.
It may take some time for your plant to fully recover from a cold, so be patient and don’t give up on it too soon.
Another potential cause for yellowing leaves in Citronella plants is compacted roots.
If your Citronella lives in a pot or plant box, it may have grown to the extent that its roots have completely taken over its home, leading to a lack of oxygen and poor growth.
A root-bound plant can no longer absorb water and nutrients efficiently, causing your Citronella to suffer.
Plant your Citronella in a big pot with adequate space to prevent compacted roots.
You can also plant it in the ground and keep the soil loose and well-drained.
Here’s what you can do:
- Repot the plant—gently remove it from its pot and loosen the tangled roots. Trim any damaged or dead roots and replant the Citronella into a pot that is two to three inches larger in diameter. Use well-draining potting mix and water thoroughly after planting.
- Provide adequate drainage—ensure that the pot you use has adequate drainage holes to prevent waterlogging and root rot. Place a layer of rocks or gravel at the bottom of the pot to improve drainage.
- Avoid overwatering—root-bound plants are especially susceptible to overwatering, so be mindful of watering frequency and avoid letting the soil stay wet for long periods.
- Proper pruning—regularly prune your Citronella plant to promote healthy growth and prevent overcrowding. Trim back any yellow leaves and damaged stems to allow for new growth.
Why are my Citronella leaves turning yellow, you ask? Yellowing leaves in Citronella plants can also be a natural part of the aging process.
As the plant grows and matures, some older leaves may turn yellow and fall off. That is a normal part of the plant’s life cycle and is not something to be concerned about.
