Plant Food

Rhododendrons are light feeders, so we recommend slow acting fertilizers which will not scorch the leaves when used as directed. In consultation with a leading fertilizer manufacturer, we developed our own slow release Rhododendron feed with all the right ingredients for best growth in the nursery and in gardens. It's a great product which lasts 3 months and now our customers love it too! Liquid feeds are excellent for quickly greening up any poor looking plants. Other products shown are useful to correct deficiencies in your soil. See Advice Centre for further details.
