I have a Holly Bush and the leaves are turning yellow.
Can anyone tell me why this is happening and what I can do to save this bush?
Spray the foliage with a liquid Iron, and apply it to the soil around the plants to correct the iron deficiency. Correct the pH of the soil by treating it with ferrous sulfate and watering it in well.
Provide acid fertlizer in the future
Take a look here to see if the iron deficiency might be your problem.
I went out and picked a branch from the tree and it is turning yellow. There is also little brown spots between the veins.
I'm headed to the local plant center now.
Do let us know what you find out from the plant center.
