Chionoides Light Yellow-Green Leaves
New to this forum and 1-year rhododendron novice.
My Chionoides leaves are light yellowish-green. But the leaves at the tip are green.
My research suggests the rhodo may lack nitrogen or sulfur. If nitrogen lack, is it advisable to fertilize now? I don't want the flower buds not to harden off for next spring.
Your advice is appreciated.
