Is there a generalized recommendation for fertilizing ornamental trees?


Abi Griffith, Horticulture Community Education Assistant

In general, as long as a tree or shrub appears healthy and is growing at an acceptable rate, we don’t typically recommend fertilizing.  Hopefully the species of ornamentals have been well chosen for the site. If you are selecting trees to plant, you’ll want to take the site conditions (light, soil texture, etc.) into consideration before selecting the appropriate tree. And refer to Bulletin #2366, Selecting, Planting, and Caring for Trees and Shrubs in the Maine Landscape
If the trees need extra TLC or any of the following has come up:

• Most young trees average about a foot of new shoot growth each year; older trees have significantly less. Is your tree growing less than expected?

• Has the color, size, or amount of foliage changed?

• Has the tree recently had disease or insect problems?

If so, the tree might benefit from fertilization and this fact sheet  could be helpful.
