Blueberry (white leaves)
My blueberry plant (Powder Blue) had small white leaves with green veins. Added iron 3 weeks ago and the leaves are now yellow with a little more green. Most of the leaves have fallen off and I noticed yesterday some leaves are getting a red tint to them. Added some Azalea plant food (magnesium?) What can I do for this poor plant? Pull the plug?
Is this a new planting? It sounds like the plant may have gone into shock. I would increase water and give it a dose of some weak sugar water. As a precaution, treat the plant with a fungicide as this can also cause these symptoms. The azalea food was a good choice as it can also be caused by a pH issue in the soil or low magnesium.
