Huge Variegated Holly Tree

Question

Can you tell me why my 20 ft holly tree has flowers but no berries, please?

Answer 1

Do you have both male and female plants? If not, this could be your problem. Poor pollination may be to blame as well. This article should also help: https://www.gardeningknowhow.com/ornamental/shrubs/holly/holly-bush-no-berries.htm
