Are Fall Fertilizations Good for Your Trees?

When to Fertilize Your Trees

With a hot summer and cold winter, trees are bound to lose vital nutrients in the soil. To help make sure your trees gain nutrients lost this summer and continue to feed over the winter, now it s great time to have us come out for fall fertilizations. Fertilizer will help replace nutrients and improve resistance to damage from disease, insects and stressful weather.

Fall Fertilization - Yay or Nay?

It was once thought that fall was NOT the right time for tree fertilizations. But what we now know is that trees, shrubs an plants use nutrients throughout the year in different ways. Now, well trained and schooled Arborists know that late fall, or about a month after the first killing frost, is the ideal time for applying fertilizers.

The reason some Arborists do not want to use fertilizers in the fall is that there is a chance that plants and trees might put on new growth if there are unseasonably warm temperatures. This is not something that is desired because since cold temperatures are certainly coming soon this could easily result in the tree being burned or damaged.

It's All in the Timing

It's actually all in the timing. You have to understand the difference between early fall and late fall fertilizations. If you fertilize in late summer or early fall, when temperatures are still warm and plants are still actively growing, it is likely new growth could occur and damage to tender new foliage could be the likely result.

You have to understand the rationale behind fall fertilizations and then it all makes sense. In late fall, deciduous trees and shrubs have lost their foliage for the year and active growth of plants and trees has slowed. Rather than put on new foliage growth, the roots of established trees or shrubs take the nutrients from the soil and apply them to important health-promoting functions, such as disease resistance and root development. The miracle in all this is that the excess nutrients are stored in the roots and become immediately available when needed for new growth in spring.

Are Your Trees Candidates for Fall Fertilization?

Let a Certified Arborist Help You Decide Whether or Not
Your Trees Need a Fall Fertilization. Not all Trees Will.
It is true though that not all established plants and trees are candidates for a regular fertilization program. That is something professionals should address. Trust your Arborist to know what can be fertilized and what should wait.

An Arborist will also know what amount of fertilizer to be given to your trees. A common mistake, and not just with trees and shrubs, is to assume fertilizer can and should always be added, and if a little is good, more is better. This is not true and can actually cause harm to the tree. Excess nutrients are wasted and can end up contaminating the soil, and the environment.

Nature has Made Trees and Plants to Withstand the Test of Time

Plants and trees are smart. They are wired that way. It is interesting to see how well trees adapt and to learn that that their internal structures are far more sophisticated than we give them credit. It's really as if deep within the tree is a built in clock, timer, calendar and monitoring systems that don’t require our meddling nearly as much as we think. They are like well running machines. They need support and maintenance, but not a major overhaul.
