Are Epsom sales good for yellow leaves on Azaleas and Rhododendrons
My azalea and Rhododendron leaves are yellow .What is missing please.Someone said Epsom Salts.Is this true!!!
Yellowing leaves can indicate a nutrient deficiency. The first step to take is to do a pH test on your soil to see if pH is correct. Azaleas like to grow in acidic soil and if the pH is too high, certain nutrients such as iron will be locked in and made unavailable to the plant for uptake. To lower the pH, a product called Acitone can be applied to rectify this problem. Azaleas can become magnesium deficient and Epsom salts can be applied to correct this deficiency. It is in soluble form which is fast acting and readily absorbed into the root system of the plant.
