The berries on holly trees are tenacious and will stay on the trees through spring.

When to Expect Berries

Holly trees will begin to produce flowers and berries in their fourth or fifth year. The arrival of berries normally occurs in midautumn. The berries are approximately ¼ of an inch in diameter and red, although yellow berries are found on some varieties of holly trees. They are the common food source for birds, squirrels and other animals during the winter months.

Growing Conditions for Berry Production

For a holly tree to produce berries, the presence of a female and male holly trees in a close enough proximity is required, for pollination. Only female trees have the capability of producing berries. If your tree is devoid of berries, there are two probable explanations: either the tree is a male or there is not a male tree close enough to produce seeds on the female tree.

Planting Requirements

When landscaping your property with hollies, you need to carefully consider where the planting location for your trees. To produce berries, you need to have at least one male tree for every three to eight female trees. The male tree needs to be within 300 feet of the females. If the male tree is not available, it is possible to graft a male tree branch onto a female plant, which will result in berries.

Maintaining Holly Trees

Holly trees are generally considered low maintenance plants but do require some basic upkeep. Mature holly trees usually do not require additional watering unless the ground is particularly dry or before the first freeze of the winter. You can lightly prune your tree throughout the year, but try to avoid heavy pruning since it can adversely affect the production of berries. Any major pruning should be done in the winter months, usually December, when the plant is dormant. When pruning your tree, make sure that the lower branches are kept longer than the higher ones.
