Q: I have a small grove of Madrones behind my house. I have put a couple of annual beds under them but nothing seems to grow under them. I have looked all over the net to no avail on this issue. I did amend the soil in the beds. I also planted a few Dogwood trees under them from tiny sticks. The trees grew last summer but then the leaves started browning at the tips and curling up. I was watering the trees every two to three days during summer. What am I doing wrong?

Gardening in raised beds has been a common practice for centuries. "Raised" means the soil level in the bed is higher than its surrounding, and "bed" implies it is small enough to work from the walkways.
Digging in the dirt gives youth a feeling of accomplishment
Try to imagine using garden tools out in the garden and yard if you couldn't see well.
There are probably few plants that are more strongly identified with this area or are held in greater affection than the madrone tree.
Volunteers give back by educating the public
Excessive summer irrigation of oak and madrone trees may promote fungal diseases such as the oak root fungus (aka armillaria root disease) and crown rot.
