Azalea Leaf Discolored

Question

Many leaves have a purple discoloration. How to treat?

Answer 1

It may also be caused by a lack of nutrients. Have the soil tested. It may be a phosphorous deficiency. Purple leaves/foliage are a sign for this deficiency. Regardless, adding a little phosphorous will not hurt the plant. Here is more information: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/phosphorus-plant-growth.htm
