2 Keys to a Healthy Landscape

Do you want a beautiful landscape that lasts for years?

If you already have a beautiful landscape, filled with perennials, shrubs and trees, you’ve invested a lot of money purchasing these plants as well as for the professional installation of them.

So, to keep your plant investment alive and well, you need regular plant health care (PHC) to keep them thriving for years to come.

In this blog post, you’ll learn about the two keys that will help your landscape plants succeed in your gardens.

First Key: Regular Fertilization Treatments

PHC is the term used for the care of trees, shrubs and perennials. It involves a plan including fertilization, insect and weed control, disease prevention and mulching.

Fertilization plays a major part in keeping your plants disease- and insect-free. The first part includes picking plants that are hardy and disease-resistant, and fertilization is the second part to keep your plants healthy.

Fertilization treatments add the right amount of nutrients to the right plants at the right time. They also help plants recover from disease or insect infestation.

And fertilization treatments help your landscape plants survive drought and hot summers.

Many people believe that the soil that houses plants should have all of the nutrients readily available for plants to absorb. However, soil chemistry changes due to construction, other plants competing for the same nutrients as well as other conditions that deplete the soil.

Plus, plants may not be able to absorb needed nutrition from the soil or air because their root zone isn’t deep enough, they’re missing certain nutrients that enable them to uptake nutrients from the soil or air, or they’re diseased.

In any case, your landscape maintenance technician will first take soil samples from your property to test it for missing nutrients and pH level. The soil’s pH level also affects how well plants can uptake nutrients into the root zone.

Your soil test results help your technician to determine the type of PHC and fertilization treatments that your trees, shrubs and perennials need to thrive as well as help them produce the best color possible.

Second Key: Insect Control

The second key, insect control, includes preventatives that keep insects from infesting a plant as well as suffocating insects that are already living in them.

Horticultural oil is a preventative control that’s applied in late winter and early fall to prevent certain insects from taking up residence and depositing their eggs within your trees and shrubs. If your ornamental woody plants are already infested with insects, the horticultural oil will suffocate soft-bodied insects and stops any eggs from hatching.

During the growing season, your landscape maintenance company will apply other pest controls. There are two ways to apply insect control to your flower beds, trees and shrubs: foliar (on the leaves) and at the base of the plants.

Here are three types of pests that can destroy your landscape plants:

  • Boring pests: If your trees and shrubs suffer from drought or disease, they’re at an increased risk for boring insects. A popular boring insect in GA includes the Asian Ambrosia Beetle. It attacks trees and shrubs that are weak due to disease, drought or other insects. Your trees or shrubs have Asian Ambrosia Beetles if they have prickly outgrowths that look like toothpicks on the trunk of the infested plant.


  • Chewing pests: These destructive pests can denude a plant by chewing on leaves, stems and other plant parts. Some examples of chewing pests include bagworms, fall webworms, and tent caterpillars.


  • Sucking pests: You can tell if you have these pests because your plant tissues will look wilted, have yellow spots or other signs of foliar damage. You may also notice a sticky substance on your plants. These pests suck the life out of your perennials, shrubs and trees.
