Pea gravel pot topper and mulch

This horticultural pea gravel makes a useful finishing layer for pots, planters and alpine troughs, with small, rounded pebbles that sit neatly around the plants. It gives exposed compost a neat gravelly covering, while helping to reduce moisture loss and soil splashes when watering.

It’s also handy for filling gaps between plants in rockeries or adding detail to miniature gardens. The smooth, rounded shape gives a softer finish than angular grit, making it well suited to delicate planting.
