Horticultural Oil Provides Year-Round Plant Protection


Azaleas can be treated!

As winter takes its last few breaths and releases its cold and icy grip upon our properties, we look around outside and begin to see the small signs of spring, pushing up through the soil.

Along with the budding blossoms and blades of green breaking through the ground comes an abundance of insects as they begin their life cycle journey.

While some of these insects play a vital role in protecting our shrubs and trees, many others are out to destroy our beloved plants and gardens, robbing us of our beautiful green environment. As with most things in life, you have to take the bad right along with the good!

Fortunately, Willow Tree and Landscape Services has a little trick that is both safe for the environment and non-toxic to you, your family, and your pets: horticultural oil.

Horticultural oil can be applied very early in the spring to trees and shrubs prone to some of the more difficult to control pests. This application is called a “dormant” application and is used to control overwintering eggs and insects such as adelgids, many types of scales, mealybugs, mites, and aphids.

Although it can be used on many types of trees and shrubs, evergreens such as hemlocks, spruce trees, and azaleas are some of the most commonly treated.

Not only is horticultural oil easy to apply, it is also surprisingly affordable. Right now is the perfect time of year to consider this treatment from Willow Tree and Landscape Services. Act now to protect your beloved trees and shrubs all season long!

What They're Saying

I'll admit it, I was very scared about having our maple tree, that was easily over 100 years old removed. I love trees and we waited seven years until it was obvious it had to come down. Willow was up for the task with the largest crane I've ever seen in my life. Yes, a "serious" pruning of our Magnolia tree was required, but that was the only way they were able to have the crane go up and over our garage.

Shawn saw my sadness about the Magnolia and explained to me that within five years I probably won't even notice it.

Less than a week later they came back today and ground the stump for us. Once again I hid because this massive machine was only several feet away from our glass patio doors. The crew was meticulous in placing up wood boards to safely protect our home. And both times they cleaned up the area to perfection.

Thank you to both amazing crews, to the owner who came out himself to assess the job and provide the estimate, and to his lovely daughter in the office who is always so nice on the phone!
