FAQ - Answer
There doesn’t appear to be any “standard” planting distance between oaks, and each species has different growth patterns. I do agree that 5-10 feet is too close for any species. However, another way to look at the situation may be to consider that not all of the plantings will survive. In addition, not all of the trees may have a desirable shape or degree of vigor and the plantings can be thinned after the trees have become established (3-5 years). Ultimately, spacing may be 15-30 feet between trees depending on your aesthetic or ecological future desired condition.
