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?
Q: We planted 17 emerald arborvitaes 3 weeks ago. We broke apart the rootball (at the suggestion of an employee at the retailer) and I've since learned that this is bad to do. We are watering regularly and have covered the area with mulch to retain moisture but our trees seem to be yellowing slightly. What can we do to encourage survival? I'm worried we may have shocked them too much. Any type of fertilizer we can use to encourage root growth/provide nutrients?
