You fertilize your lawn and feed the tomato plants in the backyard garden, so it only makes sense to give your trees some extra nutrition, too. But do you know how often to fertilize trees to keep them healthy and beautiful? Over-fertilizing can be just as detrimental to the tree as under-fertilizing, so the right timing is key to giving your trees exactly what they need.
Properly fertilizing your trees for optimal health can be tricky, but these tips from our experts in tree services in Doylestown, PA, can get you on the right track.
Do You Know What Your Tree Needs?
Trees absorb nutrients primarily through the tree root zone, which extends about 1.5 times the width of the tree’s canopy. Compacted soil or soil that’s low in essential elements like nitrogen, potassium, or phosphorus can cause a nutrient deficiency that will eventually affect the tree’s health.
Before spreading any fertilizer, take a moment to determine what the tree actually needs. Soil testing before fertilizing helps you understand what your soil needs, so you can choose a fertilizer that fills in the gaps. Slow-release fertilizers that feed the roots gradually, mimicking nature’s process of breaking down organic matter, are often the best choice.
Once you figure out the right fertilizer, the next question is how often to fertilize trees. Mature trees typically only need feeding once a year, usually in early spring or late fall. These seasons provide the ideal fertilization timing because they align with your tree’s natural growth period or root development phase, while the extra nutrients give trees a boost when they’re most receptive.
Younger or newly planted trees may need fertilizing twice a year to support strong root and canopy growth. Again, a soil test is the best way to determine whether that extra feeding is necessary.
Regardless of your tree’s age or feeding schedule, always select fertilizers specifically labeled for trees. Avoid high-nitrogen lawn fertilizers, which can harm tree roots over time.
Watch for Signs That Your Tree Needs Nutrition
Even with good soil, trees can show signs of stress if they’re not getting what they need. Signs of a nutrient deficiency include:
- Pale leaves
- Leaf discoloration
- Dead branches
- Dead branch tips
- Shorter twigs than usual
- Stunted growth
- Overall decline in vigor
These symptoms indicate that it’s time for soil testing. An arborist can advise you on what your tree needs to return to good health.
