Our multi-purpose controlled-release fertiliser is a blend of slow-releasing granules plus fast-acting plant food, providing nutrients when plants need them most. It's ideal for all plants indoors and outdoors. Use all year round. From early Spring to late Summer, gently mix the granules into the top soil and combine them by mixing thoroughly with compost. From late Autumn - Winter, use it as a top dressing on the top 2cm of compost by sprinkling and lightly forking in. Read the packaging for directions for use.
