J Arthur Bower's Epsom Salts 1kg
Epsom Salts is the best way to improve the colour of yellowing leaves, and turn them green. Rhododendrons like a little more magnesium than most shrubs, and Epsom Salts quickly corrects magnesium deficiency within the plant and the soil. Apply as directed as a top dressing to the soil, or as a liquid foliar feed.
