20L Washed Horticultural Gravel for Pots & Planters

Good drainage is one of the most important factors in keeping plants healthy, and this washed horticultural gravel makes it straightforward to get right. Placed at the base of pots and planters before adding compost, it helps excess water move freely away from roots, reducing the risk of waterlogging and root rot. It works equally well in raised beds and greenhouse borders where drainage can sometimes be a problem.

Beyond its practical benefits, the gravel also makes a clean and attractive top dressing. Spread a layer over the soil surface in containers or houseplant pots and it gives everything a neat, finished look while also helping to retain moisture and deter pests. It suits terrariums, alpine displays, and decorative outdoor arrangements just as well as everyday planting.

The 20 litre bag is a handy size for most home gardening projects, whether you are refreshing a few pots or tackling a larger raised bed. The stones are washed and ready to use straight from the bag, making the whole process quick and hassle-free.
