How To Grow Citronella Plants (FAQ)

Where Do Citronella Plants Grow Best?

The Citronella plant is one of the most versatile plants to grow. These plants can flourish both indoors, as well as outdoors. They are a great year-round plant that survives in a multitude of climates.

However, they should be brought inside before the winter frost begins to hit, That is if you want them to be around still when springtime rolls back around.

How Much Sun Does a Citronella Plant Need?

As we all know, plants need the sun to grow and synthesize. Without sunlight, they wither and die. Like many other plants, care for the Citronella plant requires no less than six hours of sunlight per day.

Even though they require up to six hours a day of sunlight, it doesn’t necessarily require direct sunlight.

One of the most beautiful aspects of the Citronella plant is that it can survive in shade, as well as in direct sunlight.

How Do You Prune Citronella?

How To Prune Citronella Plant – Besthomegear.com

Citronella plants can grow quite large (anywhere between two and four feet in height), and because of this, you are going to have to prune them.

Pruning the plant will allow the beautiful lavender blooms to show themselves, creating the scenic blossom and heavenly fragrance that Citronella plants are so well known for.

You should prune these plants in the late winter and/or early spring to get the perfect shape, along with the beautiful blooming flowers.

You should also pinch off any yellow or dead foliage on the plant. This will stimulate growth.

Pruning these plants is also essential because they are typically placed along entrance walkways and patios. Nobody wants plants spilling over into their line of travel.

What Type of Food Do Citronella Plants Require?

Plants are just like us; they need food just as we do. If you want your new Citronella plant (or plants) to grow to its maximum potential, then you can’t skimp on prices when it comes to the soil that you purchase.

The fastest-growing type of fertilizer for these plants  – and this rings true for pretty much all plants – is 5-10-15 fertilizer.

This means the fertilizer is 5% nitrogen, 10% phosphorus, and 5 % potassium. You can also use 10-10-10 if you’d like to.

Of course, you’ll want to make sure you water the soil too. But make sure you are watering around the plant (especially as it is in its stages of infancy) to keep the water from damaging the foliage.

Where Should You Plant Citronella?

As we mentioned earlier, one of the best things about the Citronella plant is that it can survive almost anywhere. They can look great near walks, porches, and gardens.

Whether you keep them indoors or out, this plant will thrive wherever you put it.  It can also make for an attractive hedge in your landscape beds.

How Do You Plant Citronella “Indoors”?

When Planting your Citronella plant inside, you will likely use a pot. But, because these plants can grow so large, you will have to get a large pot for your new plant.

It is recommended that you get a container ranging anywhere from 8 inches to 12 inches high.

You will want to fill the container to about halfway through using high-quality potting soil.

The reasoning is that it provides the plant with all the necessary nutrients. The large pot will allow the plant enough room to grow, as well as let the roots spread out and keep the plant healthy.

Make sure you put the pant in the container in a way that keeps the Citronella root around a couple of inches below the top of the container, keeping the root at the same depth it was at when you pulled it out of its original pot.

Next, make sure you water the soil enough to press it together, this eliminates any air pockets and keeps the roots being appropriately fed throughout its life cycle.  This ensures that the roots won’t become saturated when you water the plant.

Lastly, you will need to make sure you put your newly potted plant in an area of the house that gets a good amount of sunlight.

Remember, citronella plants require 4 to 6 hours of sunlight daily, or they will not grow properly.

How Do You Plant Citronella Outdoors?

Planting Outdoors In the Garden is, in my opinion, the best place to plant Citronella. Personally, I don’t particularly appreciate having plants inside the house that thrive incredibly well outside. This is especially true when it comes to plants, like citronella, that can grow up to 4 feet tall.

When you place your citronella plant in your garden outside, you should find a place that receives at least 6 hours of direct sunlight daily.

If possible, try to put it in a place that receives sunlight during the morning hours, this helps keep the plant from being scorched by the afternoon sun.

Dig a hole in your garden at the same depth as the pot the plant came in.

This means that the root ball of the Citronella plant needs to be planted at the same depth in your garden as in the original pot.

Tip: If you are planting multiple Citronella plants, then make sure you keep no less than eight inches apart. Failing to do this will put the plants in direct competition with each other, and once the roots start to take hold, they will either kill one another or not reach their full potential.

Next, you’ll need to put roughly two inches of organic compost around the plant (remember, 5-10-5 slow-release fertilizer is best for these plants). Make sure you follow the packaging instructions while planning.

This ensures you have the correct amount of room for the roots to “breathe,” allowing the plant to grow to its full potential.

Water the soil around the plants. This compacts the soil around the root and keeps air pockets from forming. Of course, you won’t want to allow the soil to dry once you have planted them.

The Citronella Myth (Mosquito Plant?)

We touched on this earlier in the post, but the idea of Citronella plants being a mosquito repellant is large enough that it bears its section in today’s post.

These plants are often touted as the best way to keep mosquitoes away. This myth has been around for so long that people have even begun to call this plant the “mosquito plant”.
The idea behind this is that, while humans love the citrusy scent of the plants, mosquitoes cannot stand the smell of it. It sounds like the perfect solution to the peskiest problem we face in the year’s warm months.

The Citronella Myth Origins

In 1984 a man by the name of Dirk Van Leenen began developing a plant that he said would eradicate mosquitoes from your backyard. In the early ’90s, his “miracle plant” finally caught worldwide attention, and the mosquito plant was born.

Subsequently, that is when people began to put this plant to the test and see if it did what it claimed to do.

Many people claimed that the plant worked; one greenhouse owner purchased roughly 50 plants for his annual Fourth of July party. After the party, he stated, “Historically, people are eaten alive. This year nobody complained at all about the insects.”

This claim sounds legitimate enough. That is, until you realize he merely trying to sell his plants.

Conclusion

Citronella plants are one of the most popular plants out there. And it isn’t because they are highly effective mosquito repellants. Instead, it is because they are easy to care for, can flourish almost anywhere, and, most importantly, look and smell amazing.
