How to Care for Your New Parkway Tree
If you’ve received a parkway tree in the last couple of years, you may have noticed something around the base—it’s called a tree diaper (some people call it a tree donut).
Here’s what you need to know:
1. What does it do?
The tree diaper absorbs rain or irrigation water and slowly releases it back into the soil when it gets dry. If there’s too much water, the tree diaper helps prevent root rot by soaking up the extra water.
2. How long should it stay on?
Leave the tree diaper in place for 3 years.
3. Should I water my new tree?
Yes! Please hand water your tree at least once a week.
4. What about mulch?
The City will mulch the new parkway trees. When you water, avoid creating a “mulch volcano”—keep mulch a few inches away from the trunk to prevent damage.
