Hi there, I live in Richmond Hill, ON, I had planted many 3 gal boxwood shrubs around the edge of the walk way last fall. Triple mix soil was used as the soil bed and I applied root booster last fall and this spring. The walk way is east facing and it gets a lot of sun light through out the day.
In the past winter, I wrapped them with burlap and sprayed them with wax to protect them from the harsh winter wind. Given the wet spring and summer we had this year, I did not water them through out the season. New buds were formed through the spring and the plants grew significantly larger.
However, the issue I currently have with the boxwoods are the new leaves. They do not have the deep green. The new layer of the boxwood has this pale green, while the inner, older leaves are still deep green.
It would be great if you can let me know what is happening, what I’m doing wrong and what I have to do to keep them healthy. THANK YOU!!!!
If there are no other symptoms and the new leaves are of a uniform light green, then it appears that your boxwood is healthy. It is normal for the new growth to be of a lighter colour, then gradually darken as the season progresses.
For your reference, here is a link a comprehensive article on Boxwood Diseases and Insect Pests if you want to double-check that your boxwoods are indeed free from pests and disease.
