The answer to 'shrub maintenance tips' is to regularly prune, fertilize, and water your shrubs to keep them healthy and looking their best. Pruning should be done 1-2 times per year, removing any dead, damaged, or overgrown branches. Use sharp, clean pruning shears and make clean cuts just above an outward-facing bud or branch. Fertilize shrubs in early spring with a balanced, slow-release fertilizer to promote growth. Water shrubs deeply, about 1-2 inches per week, adjusting as needed based on weather conditions.
It's also important to monitor for pests and diseases, and address any issues promptly. Signs of problems may include discolored leaves, insect infestations, or fungal growth. If you're unsure how to diagnose or treat a problem, it's best to consult a professional landscaper or horticulturist.
