Occasionally, you may find reused bubble wrap – this has been donated to us, and we encourage you to reuse it too.

Orders are usually packed and dispatched within 2–4 working days. We may occasionally delay dispatch during periods of extreme weather to protect your plants. We always prioritise plant health over speed of delivery.


Delivery is £4.99 for any number of items, or free on orders over £60. We deliver across the UK only.

We also offer local, bike-powered delivery in Bristol for £4.99 via Pedal Collective, a gentler option for plants and the planet.

This totally inert aggregate, moulded by quickly cooling molten rock, is exceptional for adding drainage to a pot and it's superior porous structure is famous worldwide for it's ability to house beneficial microbes like bacteria and fungi, while letting air flow freely through to avoid stagnant pockets and the risk of rot. It's porous nature also aids in insulating plant roots from extreme temperatures, offering protection during hot summers or cold winters. Moreover, lava rock's lightweight yet durable composition makes it an ideal choice for potted plants, providing stability without adding unnecessary weight.

It's neutral pH ensures compatibility with a wide range of plant species, making it a versatile option for various houseplant projects. Additionally, lava rock's natural texture and colour make it a visually appealing addition to plant displays, adding aesthetic value to indoor and outdoor spaces alike. In summary, lava rock is not only a practical choice for improving drainage and aeration but also enhances the overall health and aesthetics of potted plants.
