Description

Island Oak (Quercus tomentella) is a California native tree naturally found on the Channel Islands. This tree has more of an upright growth habit and can reach up to 50’ tall and 40’ wide. It can take a range of soil and watering conditions, so it can thrive with many different companion plantings. This is a tree that has a beautiful, regular shape, so it is a great selection for a focal point in medium-to-large gardens. As it grows, the lower branching can be pruned away to elevate the canopy and allow garden space underneath. Once it reaches a height requiring a ladder, a licensed arborist should be used for all future trimming. This tree should be planted at least six feet away from any hardscape areas, 30 feet from structures such as houses and buildings, and not near any powerlines. Shrubs and perennials should be planted about five feet away from this tree. It should be irrigated for about 45 minutes once a week when using most in-line drip irrigation systems.
