Late fall and winter are the best time to trim and prune your landscape plants. This time of year most plants are dormant and aren’t putting on new growth. Also, the leaves have come off of deciduous plants exposing the almost skeletal structure of the branches, allowing you to see more clearly the overall growth pattern and configuration of the plant.
Then get back in there and trim some more!
Just performing these small trimming tasks your plant will be thinned significantly while also being healthier and looking better when the spring growth spurts come on in March. Don’t be afraid to cut off a limb or a branch, your plant will be just fine! And when spring does come and your plant is looking too full or isn’t growing in the direction you desire feel free to trim it again, just know that in spring you’ll be trimming often as this is the time of growth.
Happy pruning!
