    Renewal pruning is accomplished by removing the largest, oldest stems (generally 1/4 to 1/3 of the total stems) as close to the ground as possible. This will stimulate new shoots to develop below the cuts which will fill in the plant creating a more dense and pleasing habit.

    Renewal pruning should be done when the plant is dormant, late fall to early spring.
