Answer: Yellowing leaves sounds like the results of some transplant shock. If there are only a few yellow leaves you can pull them off the plant. If most of the leaves are yellow leave them on the plant but feed your plant with a foliar fertilizer like Miracle Gro to help it green up. Nikko hydrangeas bloom in the late spring or early summer. Yours probably won't flower this year but it bloom for you next year after it has become established in your landscape. Holes in leaves are common this time of year. If you find insects feeding, just pick them off the plant to avoid additional holes in the leaves. Good luck with your new hydrangea.
