The answer to 'how often to shrub' is that most shrubs should be pruned and trimmed 1-2 times per year. Proper shrub maintenance is essential for keeping plants healthy, promoting growth, and maintaining an attractive landscape. Pruning encourages new growth, removes dead or damaged branches, and shapes the shrub's overall form.
The ideal frequency for shrub maintenance depends on the specific type of shrub, its growth rate, and the desired appearance. Fast-growing shrubs may need more frequent trimming, while slower-growing varieties can often get by with annual pruning. It's best to prune shrubs in late winter or early spring before new growth emerges.
