Winter is Best Time for Rejuvenation Pruning in the Mid-Atlantic

Revive overgrown or improperly pruned shrubs with a cutback that stimulates vigorous regrowth

While a light hand is apropos for many pruning jobs, sometimes a judicious but heavy hand is needed. Rejuvenation pruning is a heavy-handed but efficient method to bring overlooked, overgrown, and mismanaged shrubs back to their full potential. It is performed by removing every branch at or a few inches above ground level with a sturdy hand saw, loppers, or even a small chainsaw. For many shrubs in Mid-Atlantic gardens, winter is the perfect time to perform rejuvenation pruning. This is because in our zonal range, most woody plants are dormant and therefore exposed cuts are less likely to become pathways for pests and diseases (which are also dormant). And, when spring weather finally arrives, the shrubs will be perfectly poised  to push new, healthy growth.   

Rejuvenation pruning tames vigorous growers that have gotten out of hand 

A vigorous, healthy shrub that has become overgrown, has lost its distinctive shape or form, or has an excessive number of dead stems from overcrowding will be the best candidate for rejuvenation pruning. This technique can also be a good fix for shrubs that do not flower or fruit to their full potential because individual stems are too weak or immature to produce viable flower buds.

Multistem shrubs that generate new growth from their root systems or from the bases of stems are the best candidates for rejuvenation pruning.

Here are just a few of the shrubs that will tolerate rejuvenation pruning: 


Please note: If a shrub is in poor general health, is showing signs of stress from pests or disease, or if more than half its shoots are dead, it may be too weak to recover from a complete cutback and could be killed rather than rejuvenated by this technique.

Proper timing is important 

When a shrub is cut to the ground, it must rely on reserves stored its roots to stimulate dormant or latent buds for regrowth. Therefore, rejuvenation pruning is best performed when the plant is fully dormant and most of its nutrient reserves from the past growing season are stored in its root system. In the Mid-Atlantic region, January to early March is the ideal time for a heavy cutback. Red-twig and yellow-twig dogwoods, which are excellent for holiday decorating, may be pruned a bit earlier in winter. Dogwoods and willows grown for their vibrant stem colors will benefit from rejuvenation pruning every 3 to 5 years to replace drab older growth with a bright new crop of stems.  

Tip: Bring cut stems of flowering quince or forsythia indoors and place them in warm water to trick the dormant flower buds on old growth into producing a few out-of-season blooms.

After a shrub has been cut back, you can easily add organic mulch and an organic fertilizer to encourage new growth in spring.

Post-pruning care will help the shrub recover 

Aggressive pruning does cause stress to the plant. After cutting a shrub back, you can aid the process of regrowth by mulching around the base of the plant with well-composted organic matter. Providing adequate moisture and an appropriate fertilizer will also maximize regrowth. Choose fertilizers approved for organic use or bio stimulants that support overall soil health and aid in the process of nutrient cycling.  

Mustering the courage to try this technique may take a little faith, but if rejuvenation pruning is done in a thoughtful manner you will be rewarded with a more vibrant and attractive specimen in a few short growing seasons.
