My holly bushes have very few leaves. Mostly just spiny stems. They have been here for 8 years at least. Trimmed them last year. What is wrong with them and what can I try to make them better?
Spiny Looking Holly
Are you sure they are hollies? We have 3 types of hollies here - American holly, English holly, and Japanese holly. I would suggest that you cut off a shoot, one good and one bad section, with and without leaves, and take it to a nearby Nursery, or Arboretum - Botanical Garden, or Agricultural - Horticulture college or school and ask the people there. Its easier when you can see a sample.
Or maybe someone can answer this question better than I.
