Many of your woody stemmed plants that suffered dieback from the December freezes won’t need pruning. Still, January is the time to prune roses and deciduous plants, including crape myrtles, pears, and plums. Your Double Knock Out roses that bloom every 5-6 weeks from Spring to Frost has likely stopped blooming and are ready now through early Spring for annual pruning. Evergreens, in general, can be pruned any time of year.
Prune your azaleas after they bloom, which can vary widely depending on the variety. “Bloom times are divided into three flowering groups of early, mid, and late or fall flowering varieties,” wrote Lorna King for Garden’s Path. “The early group starts to flower in late Winter to early Spring, roughly from February to April. Midseason is considered late Spring and early summer or May and June. And the late or fall group flowers from midsummer and into fall, mid-July to October.” It would be best if you only prune reblooming azaleas after the Spring bloom. If pruned after the Fall blooms, that could stimulate growth put at risk by Winter cold.
