I'm in the process of preparing an area in my front yard for an herb garden. There are several large, old Valley Oaks trees in this area and I've read that their root system shouldn't be disturbed or watered during the summer months. Some articles say that you shouldn't plant within 10' of the trunk and some say not to plant anything under the canopy. Since the oaks are large, if I avoid planting under the canopy, I'll have only a very small area to plant. Do you have experience with planting near oaks? On other areas of our property, there are manzanita and other small shrubs growing right up against the trunks of the oaks, but they are not watered during the summer months and survive on the winter rains.
Thanks for sharing your knowledge and expertise with us! AA

Like you observed, there are many native plants that thrive under oaks - only if planted in the fall before the winter rains in CA. Oaks often have roots 2Xs wider than the foliage, so keep this in mind re your herb garden.
I am not trying to sound rude I am simply wondering the reason why? I was thinking about doing minor cultivation of things that like acid soil and don't need a lot of water but might require some.
