Horticultural Potting Grit Small Bag

Create healthier growing conditions for your plants with this small bag of Horticultural Potting Grit, an essential material for improving drainage and enhancing the structure of compost mixes. Clean, washed and ready to use, this grit is perfect for gardeners who want to prevent their growing media from becoming heavy or compacted — a common cause of weak root systems and poor plant performance.

When mixed into potting compost, horticultural grit produces a sharper, more open texture that allows excess water to drain away freely while still supporting root development. This makes it particularly valuable for plants that naturally prefer drier conditions, such as succulents, alpines, herbs and many indoor plants. It also adds stability to pots, helping to anchor taller or top-heavy plants.

This grit can also be used as a decorative top dressing on pots, rockeries or alpine beds. A surface layer helps prevent soil splash during watering, retains moisture more evenly across the compost surface and gives pots and beds a tidy, professional appearance.

For seed sowing, the addition of grit can help maintain even aeration, supporting consistent germination and reducing the risk of fungal problems. In outdoor beds and containers, it helps break up heavy soils and improves drainage where needed.

The small-bag size is ideal for smaller projects, repotting jobs, houseplants and topping up existing mixes, offering convenience without waste. Whether you are improving compost, supporting drainage in containers or preparing a rockery or alpine display, horticultural potting grit is a dependable material for building a healthier growing environment.
