Author's Notes | I have had 3 female and one male Winterberry in one of my gardens for years. This area is moist and 3/4 day sun. If we have a normal summer with adequate moisture the shrubs will be covered with red berries in the fall, until the birds find them. They are about 4 by 4 feet and never have been pruned. I provide them with acidic fertilizer in the spring and fall. |
