Proper pruning is essential for maintaining healthy, vibrant shrubs in your garden. However, knowing when to prune can be just as crucial as knowing how. Different shrubs have different blooming cycles and growth patterns, which directly impact the ideal time for pruning. This comprehensive guide breaks down pruning times for various popular shrubs, helping you keep your garden looking its best year-round. Whether you're dealing with spring bloomers, summer showstoppers, or evergreen stalwarts, this list will help you time your pruning perfectly to encourage healthy growth and abundant blooms.

SEASONAL PRUNING GUIDE

Pruning is not a one-time, one-season task. Different seasons bring different pruning needs. By following the seasonal recommendations below, you'll ensure your shrubs receive the right care at the right time, promoting vigorous growth, abundant blooms, and overall plant health. Remember, these guidelines can be adjusted based on your specific climate and the types of shrubs in your garden.

Spring (March-May):

• Prune spring-flowering shrubs immediately after blooming
• Remove winter-damaged or dead branches from all shrubs
• Prune summer-flowering shrubs before new growth begins
• Begin light pruning of evergreens as new growth starts

Summer (June-August):

• Deadhead and lightly shape spring-flowering shrubs
• Prune climbing roses after first flush of bloom
• Maintain shape of fast-growing shrubs with light pruning
• Deadhead summer-flowering shrubs to encourage more blooms

Fall (September-November):

• Avoid major pruning, especially in colder climates
• Remove dead, diseased, or damaged branches
• Lightly prune spring-flowering shrubs to shape (only if necessary, you may sacrifice spring blooms)
• In warmer climates, prune summer-flowering shrubs after blooms fade

Winter (December-February):

• Prune deciduous shrubs while dormant (except spring bloomers)
• Shape evergreen shrubs
• Perform rejuvenation pruning on overgrown deciduous shrubs
• Prune fruit-bearing shrubs to improve next season's crop

SPECIFIC SHRUBS: WHEN TO PRUNE WHAT

While seasonal guidelines provide a good framework, this detailed list helps you fine-tune your pruning schedule based on each shrub's unique growth patterns and blooming cycles. Use these recommendations as a general guide, but always consider your local climate, the specific health of your plants, and any unusual weather patterns when deciding the best time to prune.

General Pruning & Timing Tips:

• Always check the specific pruning needs of individual shrub species
• In colder regions, avoid pruning 6-8 weeks before your average first frost date
• In warmer climates, adjust timing based on your local growing seasons
