Six Good Reasons for Fertilizing
your Trees & Shrubs in the Fall
Fall. What a wonderful time of the year. You’re about to grab the kids and head to the pumpkin patch when you hear what sounds like whispers from your yard as the leaves float on the breeze.
“We’re HUNGRY!” Those are your trees and shrubs. It’s time to fertilize!
That’s right, even after a spring and summer of eating, your trees and shrubs need more food, even as the growing season winds down. (They’re kind of like your kids, they’re always hungry!)
What’s the best time to fertilize trees and shrubs in PA and NJ? Fall of course. Here’s WHY.
1. Fall Tree Fertilizer Is All About the Roots
Your trees and shrubs usually soak up fertilizer and use it to put out new leaf growth. But in the fall, their roots take those nutrients and use them to boost their health.
And those roots are important, absorbing the water and nutrients your trees and shrubs need to thrive.
If you had Superman’s X-Ray vision and could see through the ground, you’d be amazed. There are thousands of roots down there, stretching out even farther than your tree’s canopy.
That’s a lot of roots to feed.
2. Fertilize Trees and Shrubs in Fall to Replace Nutrients
Summer is tough on your trees and shrubs. All that growing takes a lot out of them. They’ve been busy providing shade, producing berries, and being homes to birds and squirrels. All that while you hang out by the pool or at the golf course. That much hard work uses up a lot of nutrients. Fall tree and shrub fertilizer replaces them.
3. Love That Spectacular Fall Color?
Speaking of hard work, imagine completely changing your color every fall. If you love those vibrant golden, orange, and crimson leaves, make sure your trees and shrubs are healthy enough to produce them.
When a tree doesn’t have enough nutrients, you’ll see it in weak, dying leaves — even before they have a chance to turn color and drift to the ground naturally.
If you notice yellowing leaves long before the fall color change, that’s a sign your trees are struggling and need a nutrient boost. Fall tree and shrub fertilizer delivers a long-lasting meal.

4. You’re Raking Up Their Free Fertilizer
In the woods, leaves and woody debris stay on the forest floor, decomposing and providing rich tasty fertilizer for all those lucky trees.
But here in lawn land, we rake those natural nutrients up. Meanwhile, your lawn is a serious competitor, gobbling up nutrients that your trees and shrubs need, too.
Give them their own fall fertilizer to level the field.
5. Fall Tree and Shrub Fertilizer for Long Healthy Life. You want your trees and shrubs to stick around, right?
When your trees and shrubs struggle to get the important nutrients they need, they get weak. That makes them more susceptible to damaging insects and diseases.
You don’t want to lose your Maple, Oak, or Crabapple, do you? Struggling trees and shrubs won’t grow as tall or as full as they could, either. Don’t wait for problems to set in. Then, it could be too late.
Fertilizing your trees and shrubs in fall is a lot easier — and cheaper — than replacing them.
6. Think Spring
We know, you’ve barely taken your first sip of pumpkin spice latte and here we are asking you to think about Spring.
Are we’re confusing you?
But fall tree and shrub fertilizer is as much about spring as it is about fall.
Trees store this fall feeding in their roots, so the nutrients are available in the spring for new growth. This is especially important for newly planted trees and shrubs.
