  • Make sure to cut no more than a third’s length of the grass blades at a time. This will allow the grass to photosynthesize well enough and keep the grass from drying out quickly after trimming. Cutting too much of it may put it at risk of not being able to recover at all. 
  • Schedule a proper fertilizing schedule based on the type of your grass and trees. It is best to do further research on this topic. As trees and grass usually have different needs based on different conditions, there isn’t a single solution when doing this.

FAQs (Frequently Asked Questions)
