Tree care

Help your tree thrive


The key to a healthy tree starts with selecting the right tree for the site conditions.  For each of the trees in our free tree program, we describe its preferred light and soil conditions.

If you would like advice, please contact us.


Trees adapt best when planted in the fall.  The dormant season gives the trees time to build a healthy root system in their new location.

Trees can be planted in spring several months before the hot, dry weather will cause stress.

Preparation of the soil and the root ball will help the tree.  Watch this one-minute video and see further planting instructions from the Arbor Day Foundation.

Summer watering

Young trees will need water for the first summer or two.  Give them a good drink every week or two when the weather is hot and dry in July and August.

After two years, the trees should have a strong enough root system to survive warm weather without extra water.
