Description

Engelmann Oak (Quercus engelmannii) is native to San Diego and Los Angeles counties in California. This tree reaches a height of 70’ and a width of up to 120’, so it is not an ideal choice for small to medium-sized gardens. If the garden space is large enough to support this tree, it is a great choice for a naturalized-style garden as a specimen tree. The natural growth habit is multi-trunk with an irregular, broad canopy. However, the lower branching can be pruned away when it is young to shape it into a single-trunk tree. Once it has been in place for a few years, the pruning should be left to a licensed arborist to keep the tree looking and performing at its best. This tree should be planted at least 10 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 10 feet away from this tree. It should be irrigated for about 45 minutes once a week when using most in-line drip irrigation systems.
