How To Use

Before you begin


Loosen the compost with your hands before use to restore its natural, crumbly texture.


Seedlings


Fill your seed tray with compost, then water gently. Sow seeds as directed on the packet and cover lightly. Keep trays out of direct sunlight while seeds germinate.


Beds & Borders


Dig a hole twice as wide and deep as the root ball. Set your plant in place, backfill with compost, and water well to help it settle in.


Pots & Baskets


Carefully remove your plant from its old pot, shake off loose compost, and place it in its new container. Fill around the roots with fresh compost and water thoroughly.


Top tip: For best results, feed your plants regularly. Try Boost All Purpose Liquid Plant Food, it’s specially designed to work with peat-reduced, peat-free and ericaceous composts, helping you grow more blooms, fruit and veg all season long.
