Is Citronella a Perennial Plant?

Indeed, citronella plants, both the grass and geranium varieties, are perennials and regrow each year.

These plants require warm temperatures to thrive, and in colder environments, they may perish during the winter season.

As a result, some gardeners opt for growing annual citronella, while others choose to uproot their citronella plants and bring them indoors for protection during the cold months.

Can Citronella Withstand Winter?

Citronella grass and citronella geraniums can survive winters in warmer zones.

Generally, anything below United States zones 10–12 is too cold for citronella grass, whereas the geranium variety exhibits slightly more resilience, being able to withstand zones 9b–11 in the United States.

Frost, however, poses a threat to citronella, which is why growing it indoors becomes favorable.

By carefully extracting and placing the citronella in a compost-filled container, one can keep it in a warm and well-lit area until spring arrives.

Does Citronella Act as a Mosquito Repellent?

Citronella serves as an effective natural insect repellent, including against mosquitoes. Insects and mammals, in general, have an aversion to most citrus scents, including citronella.

For optimal results, citronella is extracted from citronella grass and distilled into oil. Simply growing citronella grass or citronella geraniums in your garden will not sufficiently deter mosquitoes.

While crushing the leaves occasionally may have some preventive effect, citronella is primarily cultivated for its ornamental properties and is not solely relied upon for mosquito control.

Are Citronella Plants Alone Sufficient for Mosquito Control?

Relying solely on citronella plants is inadequate to keep mosquitoes away from your yard.

How to Use Citronella for Insect Repellency

According to experts, merely growing citronella is not highly effective as a mosquito repellent.

The most efficient methods of utilizing citronella involve its essential oil, candles, and natural insect sprays or lotions.

The quantity of citronella required to prevent mosquito bites is significantly higher than what is emitted by crushing the leaves of the plant.

An article from the National Library of Medicine suggests that crushed citronella leaves have no greater effect than water.

However, based on anecdotal evidence from gardeners, it is worth trying citronella plants to deter mosquitoes from your garden.

 At the very least, they emit a delightful fragrance and add vibrancy to your summer garden arrangement.

Should Citronella Plants Be Pruned?

To promote bushier growth in citronella geraniums, it is recommended to pinch out the top leaves.

This action stimulates growth at the plant’s base and contributes to a healthier and more compact appearance.

The pinched-out sections can be dried in a cool, dark place, providing you with free potpourri with a citrus scent. Additionally, trimming citronella plants encourages a second wave of flowering.

It is crucial to fertilize citronella with high-quality fertilizer after pruning to ensure the plant receives sufficient nutrients for producing another set of blooms.

This practice is particularly important for citronella plants cultivated in pots and containers.

Although many cats, dogs, and other animals like rats dislike the scent of citronella and naturally stay away from it, it is best to take precautions and ensure they cannot access any part of the plant.

Does Citronella Repel Spiders?

Citronella is not only disliked by mosquitoes and biting insects but also by spiders.

For individuals who are arachnophobic, planting citronella in the yard and utilizing citronella candles or diffusers can help keep spiders at bay.
