Do boxwood hedges have deep roots?
Boxwood plants have a shallow root system that can easily dry out. The first step to maintaining a healthy root system is planting at the proper depth. Set plants such that the root ball sits just an 1/8 inch above the soil surface. This will allow plants to settle properly without becoming too deep.

Apply the biological insecticide as soon as you see caterpillars or your pheromone traps start to fill up with male box tree moths. The treatment is only effective for about 10 days as it is broken down by UV light so you may need to reapply more than once when the caterpillars are active.

We offer two options for treating box hedge caterpillars. The first is a pesticide (insecticide) which is extremely fast and effective. We also offer a biological control treatment which is slower but is extremely safe for pets and people. For this treatment we spray the plants with Bacillus bacteria which kills the caterpillars.
