Perlite is the perfect ingredient for adding oxygen back into a potting mix to prevent root rot. These white crunchy granules are particularly useful for plants that require well-aerated soil to grow, or even rooting a cutting in perlite. The price includes FREE Delivery across mainland U.K.!
Our refined perlite comes in a resealable bag, meaning that you can always use it later if you have too much. It'll also stay fresh for at least two years once opened, so never worry about it going off shortly after purchase.

If you're intrigued by the idea of propagating a cutting in perlite, you're not alone. Similarly to rooting a plant in sphagnum moss, all you need to do is find a suitable pot and fill it near to the top with the perlite. We recommend using an Orchid container with drainage for the best results. Simply pour water through the perlite for 8 seconds and place your cutting's base in the middle. Wrap some cling film around the top of the pot to create a lid-effect, keeping the cuttings foliage above the film to breathe. This will lock in the humidity and allow light to penetrate the pot, thus creating the optimal condition to develop roots. Keep in a bright indirect location and on a drip-tray; water if necessary by taking off the cling film to pour water through the perlite.
Once the roots are a few inches in length, you can safely repot it into our Houseplant Potting Mix with a new pot to continue growth as a normal plant. The perlite can be used to root another cutting if it's still crunchy and healthy!
Perlite is great for mixing with compost to reinforce drainage and oxygen into its structure. The pot sizes below illustrate the ideal amount of perlite needed for repotting a plant into your specific pot.
|Small||500ml||18cm pots or smaller, & for use in a terrarium|
|Medium||1L||20cm - 25.4cm pots, & to root cuttings|
|Large||2.5L||30.5cm pots or larger, or for houseplant enthusiasts who like to have perlite on-hand|
