Alternative EarthCare discusses why applying dormant oils during spring tree spraying is important.


Incorporating dormant oil applications in the fall will help to ensure that applications are timely and consistent. Dormant oils should be applied to trees and shrubs to destroy the insect eggs for the best effectiveness, making it important to adhere to a treatment schedule. Utilizing a professional service will keep treatments on schedule and will produce the best results.



Insects need to be Controlled before they become uncontrollable. It’s important to address overwintering insect populations before they become active again in the spring and begin destroying trees and shrubs. Due to rapidly growing populations and the devastation that they can cause, ensuring that the problem is addressed early is vital for tree health.


Temperature matters when it comes to tree maintenance. Temperatures should be in between 40 degrees and 70 degrees Fahrenheit when applying dormant oils. If it’s too cold, the treatments will be useless because the insects won’t be accessible. Additionally, applying dormant oils when it’s too cold can cause damage to the bark. On the flip side, if treatments occur too far into in the season, it can be ineffective due to rapidly reproducing insects and the damage that they can cause in a short time, as well as potentially damaging new tree growth.


It’s always a good idea to utilize a professional service when addressing tree care to ensure that both timing and processes are handled appropriately. Professionals will take into account the different chemicals and processes being utilized to provide the most efficient and effective treatments possible. Professionals will also give consideration to all chemical combinations being used for the various landscaping treatments to prevent any bad reactions.
