Hydroponic growers use clay pebbles as a soiless medium which will absorb water and nutrients - they make a great alternative to bark when growing Orchids. You can even use them to pot up artificial plants for a completely maintenance free-display!

If you’re not quite ready to go soil free, try mixing them into a growing medium to improve aeration at the plant roots.A ratio of 1 part pebbles to 9 parts compost makes the perfect blend. Use a layer at the bottom of pot plants to improve drainage – they make a lightweight alternative to grit! For a professional finish to your house plants, add a layer of pebbles to the top of the pot.

With a multitude of uses, clay pebbles are both useful and decorative! These porous, pH neutral pebbles are clean, lightweight, easy to use and won’t break down or become compacted over time.
