Are madrone trees mean?

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?
