How to Repurpose Luxury Candle Jars for Plants UK Guide
The First Step: Safely Cleaning Your Candle Jar
This guide covers everything you need to know about how to repurpose luxury candle jars for plants uk, with practical recommendations from Matty’s Candles.
Before your elegant candle jar can begin its new life, it must be meticulously cleaned. Any remaining wax residue can harm plant roots and look unsightly. As experts in premium coconut and rapeseed wax blends, we know the best ways to handle this process without damaging your beautiful vessel. There are two primary, safe methods we recommend.
Method 1: The Freezing Technique
This is perhaps the simplest and cleanest method, particularly effective for the types of natural waxes we use at Matty’s Candles. Our coconut and rapeseed wax blend is formulated to be slightly softer than paraffin, but it still contracts beautifully when chilled, making removal straightforward.
First, place your candle jar in the freezer for several hours, or overnight if possible. The cold temperature will cause the wax to shrink and harden, pulling away from the sides of the glass. Once thoroughly chilled, turn the jar upside down. The remaining wax disc should fall out. If it’s a little stubborn, a gentle tap on the bottom of the jar or the careful use of a butter knife to pry an edge will dislodge it. Never use a sharp knife, as this could scratch the glass or cause it to break.
Removing the Wick Sustainer
After the main wax disc is out, you will likely find a small metal disc—the wick sustainer—stuck to the bottom of the jar. This is typically held in place with a strong adhesive dot. To remove it, use a spoon or the end of a butter knife to gently pry it off. A little bit of warm water can also help to soften the glue. Once removed, you can proceed to the final wash.
Method 2: The Gentle Heat Method (Bain-Marie)
For any particularly stubborn remnants of wax, a gentle heat method works wonders. It’s crucial to avoid extreme or direct heat, which can cause thermal shock and crack the glass. Never place your candle jar in a microwave, as the metal wick sustainer can cause sparks and fire. Likewise, avoid the oven.
Instead, create a simple bain-marie. Place a folded tea towel in the bottom of a saucepan to protect the glass and place your candle jar on top. Fill the saucepan with a few inches of warm (not boiling) water, ensuring the water level is below the jar’s rim. Gently heat the water on the hob over a low setting. As the water warms, the wax inside the jar will melt. Once it is completely liquid, carefully remove the jar from the pan (using an oven mitt) and pour the melted wax into a bin—never down the sink, as it will solidify and cause severe blockages.
Final Polish and De-greasing
Whichever method you choose, a final clean is essential. Use a paper towel to wipe out any final oily residue from the inside of the jar. Afterwards, wash the jar thoroughly with hot, soapy water and a soft sponge. A good rinse and a polish with a microfibre cloth will leave it sparkling and ready for its next chapter.
Preparing Your Jar for its New Life as a Planter
Now that you have a pristine glass vessel, the next stage is to transform it into a suitable home for a plant. This is the most important part of learning **how to repurpose luxury candle jars for plants in the UK**, as getting it wrong can lead to an unhappy plant. The primary consideration is drainage, a vital factor for root health.
The Crucial Question: To Drill or Not to Drill?
Most plant pots have a hole in the bottom to allow excess water to escape. Without this, water can pool at the base, leading to root rot, which is one of the most common reasons houseplants fail. You have two options when it comes to your candle jar.
For the dedicated DIY enthusiast, drilling a drainage hole is possible. This requires a specific tool—a diamond-tipped drill bit—along with patience and safety precautions. The process involves keeping the glass wet to prevent overheating and cracking, wearing safety goggles, and applying slow, steady pressure. While effective, it carries the risk of breaking the jar.
The far simpler and safer approach is the ‘cachepot’ method. A cachepot (from the French for ‘to hide a pot’) is a decorative outer container that houses the plant in its original, functional nursery pot. This means you can enjoy the aesthetic of your beautiful Matty’s Candles jar without any risk of waterlogging your plant or breaking the glass. You simply take the inner plastic pot out for watering, let it drain completely, and then place it back inside the jar.
Creating a Drainage Layer (No-Drill Method)
Even when using the cachepot method, a small drainage layer at the bottom of the candle jar is a wise addition. This creates a buffer zone that elevates the nursery pot, ensuring it never sits directly in any water that might accidentally accumulate. This is a simple but effective insurance policy for your plant’s health.
To create this layer, simply add an inch or two of small pebbles, horticultural grit, or decorative gravel to the bottom of your clean candle jar. For an extra touch of horticultural science, you can add a thin layer of activated charcoal on top of the stones. Charcoal helps to filter impurities and can absorb odours, keeping the environment within the pot fresh.
Choosing the Perfect Plants for Your Candle Jar Planter
Not all plants are created equal, especially when it comes to living in a small, enclosed space. The key is to select species that are slow-growing, have compact root systems, and are tolerant of the slightly restricted conditions a candle jar provides. Luckily, many of the most popular and stylish houseplants fit this description perfectly.
Top Plant Choices for Candle Jars
When considering **how to repurpose luxury candle jars for plants in the UK**, your choice of greenery is paramount. Here are our top recommendations:
* **Succulents and Cacti:** These are the undisputed champions of small-container gardening. Their low water requirements make them ideal for a setup without direct drainage. Choose from a huge variety of shapes and colours, such as the rosette-forming Echeveria, the striped Haworthia (Zebra Plant), or the classic ‘Hens and Chicks’ (Sempervivum).
* **Air Plants (Tillandsia):** For the ultimate low-maintenance option, look no further than air plants. These fascinating plants require no soil at all, absorbing moisture and nutrients from the air through their leaves. You can simply place one on a bed of decorative stones or moss inside your candle jar for an effortlessly chic display.
* **Small Cuttings and Offsets:** Many common houseplants produce ‘babies’ that are perfect for starting in a small jar. A spider plantlet, a small Pilea peperomioides (Chinese Money Plant) offset, or a cutting from a Pothos (Devil’s Ivy) vine are all excellent candidates. They will happily live in a small jar for a long time before needing to be potted on.
Once your new plant is happily settled, you can celebrate your sustainable creativity by lighting a brand new candle from our exquisite collection and enjoying the beautiful ambiance.
A Guide to Planting and Potting
Using the recommended cachepot method, ‘planting’ is incredibly simple. First, choose a plant in a nursery pot that fits comfortably inside your candle jar, with a little room to spare. Place your drainage layer of pebbles in the bottom of the glass jar. Then, simply lower the plant, still in its nursery pot, into the jar. If there’s a significant gap between the top of the nursery pot and the rim of the candle jar, you can fill it with decorative moss or more pebbles for a polished look.
Styling and Caring for Your Upcycled Planters
The final step is to integrate your new creation into your home’s decor and learn the simple rules of care. This is where your upcycled jar transforms from a simple project into a stunning interior design feature. The beauty of a luxury candle jar is its inherent style, which provides a perfect foundation for a beautiful plant display.
Creative Styling Ideas
Don’t just create one—create a collection! A group of three upcycled planters in varying sizes on a windowsill or bookshelf makes a powerful visual statement. Play with textures by using different top dressings; a layer of white sand can create a coastal feel, while dark gravel offers a more modern, minimalist look. Consider the jar itself: a dark, smoky glass jar might pair beautifully with the deep green leaves of a ZZ plant cutting, while a clear jar is perfect for showing off layered sand and stone.
Watering Wisdom for No-Drainage Pots
This is the golden rule of caring for plants in cachepots: less is more. The single biggest danger is overwatering. Because there is no escape route for excess water, it’s vital you don’t give the plant more than it needs. The best practice is to remove the inner nursery pot from the candle jar every week or two. Feel the soil; if it is dry an inch below the surface, it’s time to water. Take the pot to a sink, water it thoroughly until water runs from the drainage holes, and then—this is the crucial part—let it drain completely for 10-15 minutes before returning it to its decorative glass home. For more detailed guidance on specific species, the Royal Horticultural Society’s page on houseplant care is an excellent resource.
Giving a second life to your candle jar is a wonderfully satisfying project that aligns perfectly with a sustainable lifestyle. It’s a small act that reduces waste and brings a touch of nature indoors. When you choose a premium candle, you’re not just buying a fragrance; you’re investing in a beautiful object that can last long after the flame has gone out.

Frequently Asked Questions about Repurposing Candle Jars
What plants are best for small candle jars?
The best plants are those that are slow-growing and have low water needs. Succulents like Echeveria and Haworthia, most cacti, and soil-free air plants (Tillandsia) are perfect choices. Small cuttings from larger plants like Spider Plants or Pothos also work very well.
Can I plant directly into a candle jar without drainage holes?
It is strongly advised not to. Planting directly into a vessel without drainage makes it extremely difficult to manage moisture levels and almost always leads to root rot. The much safer and more successful method is to use the jar as a ‘cachepot’ to hold the plant in its plastic nursery pot.
How do I get the last bit of wax out of a candle jar?
The easiest way is the freezing method. Place the jar in your freezer for a few hours. The cold causes the wax to shrink and harden, allowing it to be popped out easily. Alternatively, you can place the jar in a pan of warm water (a bain-marie) to gently melt the remaining wax, which you can then pour into the bin.
Is it safe to drill a hole in a glass candle jar?
It can be done, but it carries a risk of the glass cracking or shattering. It requires a special diamond-tipped drill bit, water to keep the glass cool, and proper safety equipment like goggles. For most people, the no-drill ‘cachepot’ method is a far safer and easier alternative.
Why choose coconut and rapeseed wax candles?
At Matty’s Candles, we exclusively use a natural blend of coconut and rapeseed wax. This blend is vegan, paraffin-free, and soy-free, offering a cleaner, longer burn than many alternatives. It’s a sustainable choice that provides an excellent scent throw and results in a beautiful, reusable jar at the end of its life.
