The roots which take up water and nutrients are in the upper 12". The critical root disease zone for an oak is within 6-10 ft of the trunk. Do not irrigate plants or disturb the soil in this area. Outside this zone but within the drip line one deep watering per month is allowable for your plantings. The leaf mulch that accumulates under a large coast live oak increases soil moisture and available nutrients, improves soil structure and moderates soil temperature. It’s a valuable resource that can be used in other parts of the garden. Never remove the entire insulating layer of leaves from under a trees canopy and don’t allow leaf mulch to cover the trunk. http://www.californiaoaks.org/ExtAssets/CompatiblePlantsUnder&AroundOaks.pdf 15
