Introduction to Citronella Candles

This week, we’re delving into the world of citronella candles — a delightful addition to your home and outdoor gatherings! Not only do they provide a warm, inviting glow, but they also offer a multitude of benefits. In this post, we’ll explore what citronella is, its advantages, how to craft your own candles at home, and some excellent scent pairings to enhance your candle experience. Let’s get started!


What are Citronella Candles?

Citronella is an essential oil derived from the leaves and stems of various species of lemongrass, particularly Cymbopogon nardus and Cymbopogon winterianus. This aromatic herb is native to the tropical regions of Asia and has been utilised for centuries for numerous purposes. Historically, citronella has been prized not only for its invigorating scent but also for its traditional applications in perfumes and natural remedies. Its distinctive aroma, characterised by a fresh and citrusy note, has made it popular in candles, creating a pleasant atmosphere for relaxation and enjoyment.

So, what are the benefits of Citronella?

  • One of the standout features of citronella candles is their natural aroma. The uplifting scent can instantly enhance any space, creating a refreshing and inviting atmosphere. Whether you’re hosting an outdoor gathering or simply enjoying a quiet evening at home, the aroma of citronella can elevate your mood and encourage relaxation. 

  • Additionally, citronella candles are perfect for outdoor spaces. They can help set the scene for a cosy evening on the patio or a lively barbecue with friends when lit. The warm glow of candlelight, combined with the soothing scent of citronella, can transform your outdoor experience.

  • It's important to note that while citronella candles are often associated with insect-repelling properties, our focus here is purely on their benefits for personal enjoyment. We want to stress that these candles are intended for home use and not for commercial sale. Please bear in mind that claims of insect-repellent properties require biocide registration. For more information, please refer to this website . Always remember to use them responsibly and keep them out of reach of children and pets!

Aromatic and Aesthetic Appeal


The multifaceted appeal of citronella candles goes beyond their practical benefits. These illuminating devices enhance the outdoor ambience while emitting a delightful, lemony fragrance that enriches the atmosphere of garden parties, patio gatherings, and evenings of relaxation.

A Step-By-Step DIY Guide to Making Citronella Candles

Preparation and Safety Tips

Establishing proper safety protocols is vital before starting candle creation! Always work in a well-ventilated area, maintain a tidy workspace, and ensure that the candles are used safely once they are complete. 




Materials Needed






Step-By-Step Instructions

Making your own citronella candles is a fun and rewarding project! We've put together a simple guide to help you create your own at home, not to mention a video tutorial (beginner-friendly) so you can follow along step by step:

1. Melt the Wax: Begin by melting your candle wax using a double boiler or placing it in a microwave-safe bowl. If using a microwave, heat in short bursts, stirring in between until fully melted.


2. Add Citronella Oil: Once the wax has melted (about 75°C), remove it from the heat and allow it to cool slightly. Check the temperature regularly before adding your oil. Ideally, it should be around 60°C (140°F). Stir in your citronella oil—aim for a fragrance load of 6-10%, meaning that 6-10% of the wax's weight should be citronella oil. For instance, approximately 28g (1 ounce) of citronella oil per 454g (1lb) of wax. Please feel free to consult our article " How To Calculate Fragrance Scent Load " for the precise amounts required for your desired total weight.


3. Prepare the Containers: While the wax is cooling, secure the wick to the bottom of your container using a wick sticker . Make sure the wick stands upright and is centred - you don't want any wonky wicks!


4. Pour the Mixture: Carefully pour the scented wax into your prepared containers, leaving around 1-2cm from the top.

6. Allow to Cool: Let your candles cool completely at room temperature. This may take a few hours, so be patient!


7. Trim the Wick: Once the candle has cooled, trim the wick to about ¼ inch above the wax surface.


8. Curing Time: Although it’s incredibly tempting to light your candle now that it’s completed, you’ll achieve the best results if you’re patient and let it cure for at least 14 days. This waiting period allows the fragrance to bond thoroughly with the wax, enhancing the candle's scent.


9. Light It Up: Time to enjoy your DIY creation! When lighting a candle for the first time you want to give it a good initial burn, up to 4 hours is recommended. Candles have memories so ensure that initial melt pool is even, as this helps to prevent issues like candle tunnelling!

Experimenting with scent combinations enables you to craft personalised candles that reflect your tastes and the ambience you wish to evoke.

Lavender : A very popular scent combination, this calming scent pairs beautifully with the zesty notes of citronella, making it perfect for relaxation.

Eucalyptus : Incorporating eucalyptus can create a refreshing and invigorating blend that enhances the outdoor atmosphere.

Lemon : Dial the citrus up to the max! To achieve a brighter, citrusy vibe, lemon elevates the freshness of citronella, making it even more uplifting.

Tips for Maximising the Effectiveness of Citronella Candles


Placement and Usage Tips



The effectiveness of citronella candles is significantly influenced by their placement. Arrange the candles around seating areas in a perimeter, maintaining a distance of about 1.5 to 2 metres (4 to 6 feet) between each one. Take into account wind patterns and ensure proper ventilation, avoiding direct drafts that could prevent that delightful scent from ever reaching your nose!

Maintenance and Storage Guidelines



Keep your candles burning bright and long by giving them some TLC! Snip those wicks to a neat ¼ inch before lighting, stash them in cool, shady spots away from sunbathing, and shield them from extreme temperatures. For a top-notch glow, pop a lid on when they're off-duty to lock in their magical oils.
