When it comes to lawn care, the trees you take care of can be a special kind of project in themselves. Different types of trees need different levels of love and attention, and when using tree fertilizer, it is easy to overdo it without even knowing it. To keep you from committing the cardinal sins of arbor care, here are some tips on making sure you’re not over-fertilizing your trees.

Fast Isn’t Better

Steer away from fast-release fertilizers for treating your lawn, no matter how tempting they may sound. The slow growth process of trees cannot be fast-tracked the same way heating up leftovers can be with a microwave. If your trees are over-loaded with too many nutrients all at once they won’t be able to process them properly and it could make them sick. As with people who aren’t food eating world champions, so it is with trees. They need time to digest.

More Isn’t Always More

If your trees are looking a little under the weather, dumping an extra heaping pile of fertilizer isn’t going to make it better. The issue is similar to using fast-release fertilizer. Overloading a tree’s root systems with extra fertilizer is not going to magically make it better.


Different types of trees like more of certain kinds of nutrients and less of others. Using an exactly balanced blend of nitrogen, potassium, and phosphorus in your fertilizer may sound like you are giving your trees a well-balanced meal, but that can actually be really bad for trees. It is better to consult or hire and expert who knows what types of fertilizer your trees will actually benefit from.


Along with helping you understand the best fertilizers, professional arborists can actually perform pH tests on the soil around your trees to give you even more insight into the health and growth of your trees. They will also be able to help you identify any disease in the trees that you may be unfamiliar with, along with insect damage or moisture issues in the soil, and can even determine if your trees are not getting the sunlight that they need.

Some remediation techniques are a little complicated for trees, and utilize not only pruning but flushing out the root system of the trees themselves. This can also involve adding a certain kind of carbon-based mulch and flushing the tree more than once.

In Conclusion

It’s recommended that you find a professional tree service that is certified by the Tree Care Industry Association, or TCIA, because their company will be accountable to a larger body of tree care and remediation techniques. That means they will be making educated decisions, and they will be up-to-date on any new information or trends in the tree care industry that could benefit you.
