You want your tree to be its best. To grow larger. To live longer. To look better.
When you fertilize your trees, you replace necessary minerals and nutrients that are missing from the soil.
Does my tree need to be fertilized?
In forests, soils have nutrients galore. In our yards, that’s not often the case.
As we sweep away leaves, twigs and fallen bark, we’re removing potential recycling of nutrients for the soil. Additionally, grass around our trees is unnatural and often outcompetes trees for available nutrients and water. That’s why we need to fertilize our trees – to mimic nature.
Look for signs that your tree is lacking nutrients in the soil.
If you see these signs, fertilization can be part of a holistic approach to restore your plant’s health.
- Shorter than normal annual twig growth
- Undersized leaves that are fewer in number
- Dead branches and branch tips
- Leaf veins darker than leaf margins
- Leaves any other than dark green, such as yellow or purple
Still unsure if your tree needs to be fertilized? Have your local arborist inspect your tree and test the soil.
Should I fertilize my trees in spring?
At Davey, we fertilize with Arbor Green PRO®.
When using Arbor Green PRO® products, you can fertilize your trees at any time of the year. With traditional fertilizers, you have to carefully plan when to apply it, so you maximize the benefits.
With Arbor Green PRO®, you don’t have to worry about “the best time to fertilize.” The product is designed to slowly release its nutrients uniformly over time, regardless of when it was applied. Our product was also designed to have the lowest possible risk for “fertilizer burn” that can be found on the market.
If your tree appears to be lacking nutrients, it’s usually best to fertilize sooner rather than later.
Find a tree fertilizer with a slow, controlled release and low burn potential.
Also, look for a fertilizer with three key macro-nutrients: nitrogen (N), phosphorus (P) and potassium (K). This blend, found in Davey’s Arbor Green PRO®, mimics the natural environment to give trees the nutrients they need to thrive.
This tree fertilizer releases nutrients slowly and contains the best NPK ratio for woody plants. Arbor Green PRO® also contains PPA, an amino acid that helps enhance nutrient availability while reducing nutrient loss from rain or watering.
