We’re close to Boulder Valley’s “average last frost” date, and except for being windy and dry, it sure feels like Spring! Lots of gardeners are asking whether it’s safe to prune now, especially roses and shrubs. The answer is YES! But…..
Pay attention to the characteristics of the particular shrubs and roses you’re thinking of pruning. If the shrubs in question won’t be in bloom until summer or fall (for example: Blue Mist Spirea, Rose of Sharon, Russian Sage, Rabbit Brush, Seven Sons, Butterfly Bush, ‘Mongolian Gold’ Bush Clematis), now is a great time to prune them for compact form, removal of winter-kill and dead tips. These shrubs bloom on new (this year’s) wood, so you won’t be diminishing their bloom potential by pruning now.
