Why You Need a Good Fertilizer for Trees and Shrubs

Trees and shrubs require fertilization in urban or suburban communities. Modern methods of home-building establish negative growth environments for plants.

Sometimes, healthy topsoil is stripped entirely and not replaced. Strong equipment scrapes fertile soil and compacts it, eliminating aeration and drainage. Thus, trees and shrubs can quickly suffer from nutrient deficiency.

Plants are overwhelmed by highways and streets and must contend for nutrients with grass. Proper fertilization in this setting is essential for landscape plants as their root zone can take much longer to develop with hard soil.

Nutrient deficiencies can cause your trees and shrubs to send out roots in directions you don’t want them to, which can cause them to be unstable as they mature. Most of these will not need the square feet calculation you would normally. This is true with the spikes. (Find the Best Soil Test Kit)

Lastly, you may be able to balance your soil pH as well as increase your soil fertility.

Fertilizer For Trees And Shrubs Buying Guide

There are things to know when buying fertilizer, and in some ways, there isn’t too much that can differ. However, fertilizer isn’t a cure-all for all plant issues.

Besides this, not every fertilizer will work to deliver tremendous results. You will also find the right time and the wrong time to use them.

Soil testing is vital to find the type of fertilizer you need. You will need to conduct a soil test.

Getting soil test results will tell you all about the alkalinity or acidity of your soil, and you can then balance your pH levels.

After you have had your soil tested, your plants will also let you know if they need fertilizer through their appearance.

If you see yellow leaves, small twig growth, and your plants are low nutrients, you will need fertilizer.

Underlying problems, such as disease-ridden plants and insect excess, need fixing. It’s vital to take care of these basic issues before adding fertilizer.

You will find fertilizer won’t work if your trees are not at the best stage when you need them.

Opt for a complete fertilizer, such as 16-4-8, 12-6-6, or 12-4-8, unless phosphorus and potassium levels are optimal.

Fertilizers are fast-release or slow-release, or extended-release. Fast-release is absorbed in the soil within several minutes.

Fast-release fertilizers work fast but can leach into the soil, and thus you lose nutrients from your trees.

These fertilizers work best with sandy and well-drained soils. Fast-release also offers a quick pick-up. Slow-released are better for building up young plants.

Chemical fertilizers can also be used to repel weeds, although this does depend on the brand and variety. (Learn How to Grow Lemon Tree From Seed)
