Cutting back the right plants can promote healthy growth, prolong blooming, and improve air circulation. But trimming the wrong ones? That could mean fewer flowers, stunted growth, or unnecessary stress during the heat of summer. Let\u2019s dig into which plants to cut back in May\u2014and which ones are better left alone. \ud83c\udf3f What to Prune in May 1. Spring-Flowering Shrubs (Once They&#8217;ve Bloomed) Think: Forsythia, Lilac, Azaleas, Viburnum These bloom on old wood\u2014which means the buds for next year\u2019s flowers are already forming right after blooming. The best time to prune them is immediately after flowers fade. Avoid pruning too late into summer, or you risk cutting off next year\u2019s flower buds. 2. Herbaceous Perennials (Clean-Up and Shape-Up Time) Think: Salvia, Catmint, Coreopsis, Shasta Daisy Many perennials are now emerging and getting leggy. Pruning in May helps prevent them from flopping over in midsummer. Bonus: For plants like salvia, deadheading throughout summer after the first bloom can trigger a strong second flush. 3. Cool-Season Annuals That Are Bolting Think: Lettuce, Cilantro, Spinach (in flower beds or edible gardens) By mid-to-late May, cooler-loving greens start bolting\u2014meaning they flower and go to seed. 4. Roses (Especially Repeat Bloomers) Avoid heavy pruning\u2014save that for late winter or early spring. 5. Woody Herbs Think: Thyme, Oregano, Sage, Lavender These can get woody and leggy if left untrimmed. May is a perfect time for a light haircut. This helps herbs stay compact, bushy, and productive through the summer. \ud83d\udeab What NOT to Prune in May 1. Summer-Flowering Shrubs (Too Early!) Think: Hydrangea paniculata, Rose of Sharon, Butterfly Bush These bloom on new wood. While they benefit from pruning, that should have happened in early spring, before growth began. Pruning now can: Let them do their thing for now. 2. Evergreens Think: Boxwood, Arborvitae, Junipers, Spruce These should be pruned earlier (late winter or early spring) or later (after their spring growth flush). 3. Fruit Trees While winter is the main pruning season for apples, pears, and stone fruits, some light pruning in May is okay for removing water sprouts or dead wood\u2014but avoid heavy cuts. 4. Hydrangea macrophylla (Bigleaf Hydrangeas) These bloom on old wood and often start setting buds in late spring. Pruning in May could remove your flower show entirely. If you must, only remove dead or damaged stems. \ud83c\udf31 General May Pruning Tips \ud83c\udf1e Wrapping It All Up May is a time of transition in the garden\u2014between spring\u2019s freshness and summer\u2019s full heat.
