Question by weinberg69

My azaleas, new Encore and established regular azaleas, have light spots on the leaves. I fertilized them. Was this correct? How long should I wait for the problem to correct itself? If it doesn't, should I fertized them again? Thanks

Light colored leaves can indicate a need for fertilizer so give the application a few weeks to work before expecting to see a change. Azaleas like acidic soils. If yours is alkaline you might feed with an acidified fertilizer such as one formulated for Rhododendrons and Azaleas or use Miracid. You can also mulch over the soil beneath the plants with compost, shredded oak leaves, peat moss or pine needles to help lower the pH. Good luck with your azaleas.
