The answer to 'shrub schedule' is that the ideal schedule for maintaining shrubs depends on the specific type of shrub, its growth habits, and the local climate. As a general rule, most shrubs should be pruned and trimmed at least once per year, typically in late winter or early spring before new growth begins. This helps maintain their shape, promote healthy growth, and remove any dead or damaged branches.
Evergreen shrubs like boxwoods, holly, and juniper may only need light trimming once or twice per year, while deciduous shrubs like azaleas, hydrangeas, and roses often benefit from more frequent pruning, sometimes every 6-12 months. Shrubs that bloom in the spring should be pruned after flowering, while summer-blooming shrubs are best pruned in late winter or early spring.
