In 2014-2015 the red headed sawfly were the most active they've been during the past seven years. Having a three-week lifespan, they target Ponderosa pines, typically in March, but feed on other pines in early May. Associated with east coast locations, the sawfly has slowly moved westward - and can quickly kill a ponderosa pine. Luckily, orthene can control it - which is the main contact insecticide we use in our general spray.

If I cut my shrub to the ground will it grow back?
I can’t give you a guarantee, but generally plants with multiple stems coming up from the ground will be fine when cut down to the ground.
