Top Tip
Iron is not very mobile in the plant so for very iron demanding plants such acid species such as rhododendrons, azaleas and camelia or species that often show deficiency such a Buxus (box) and hydrangea, foliar applications are recommended. For foliar application add 2-3mls of Gro-Expert Organic Liquid Iron to every 1 litre of spray. It may take more than one application to correct severe deficiency so apply as necessary at 7-day intervals.
