I'm fertilizing some trees today. This is something I like to do every spring and fall. It's a little bit later in the season that I like it to be. We just move into a new place. So better late than never. I like to do it on young trees and any tree that's exhibiting any kind of health issue. I typically don't fertilize big established mature trees that are looking healthy. Every once in a while I'll throw some fertilizer on them just to keep them happy, because happy plants are much more able to withstand any kind of weather condition and tests and disease. Let me show you what I like to use. I'm using tree tone, which is a slow release, organic fertilizer. First thing you need to do is figure out how many pounds you need and there's always a nice application rate chart on the back of the bag. So to figure out what you need to measure 4ft feet up the trunk from the ground.
And at that point you measure the diameter of the trunk and that will tell you how many pounds to use. The goal when you're applying your fertilizer is to get that fertilizer as close to active roots as you can't. So you can do it two different ways. Best way is to use an auger and make twelve to fifteen inch deep holes every two feet along the drip line of the tree, and you can find these four fairly inexpensive. If you already have a drill, you can pick one of these up for fifteen twenty dollars right around there. If you do not want to make that sort of investment, you can just go ahead and use a shovel and lift up little pieces of sod. Throw your fertilizer under the sod back down and you're good to go. The discipline of your tree is where the outer branches end. Like think if your tree has a great big umbrella and wherever the rain would drip off the umbrella, that's where the drip line is of the treetops. Easiest way for me to remember it. Oftentimes the root system of your tree spreads out several times wider than the actual canopy and the water and nutrient absorption is the most active right at the drip line. So that's where we want to get our fertilizer. So we are going to be making twelve to fifteen inch holes every couple feet all the way around the tree. So here we go. All right. Pro tip of the day, make sure to charge your drill batteries so you don't have to upgrade to a plug in drill and deal with all the extension cords. Now I'm going to take the amount of fertilizer that I need and divided evenly among the holes that I just made. Now I'm going to Waterton really well, this is a very important step because this is what pushes the fertilizer even closer to the roots and makes a tree be able to utilize it and take it up into its system.
