Horticultural Restoration: Pruning

Established landscapes can be so very lovely and so very intimidating. Often we do not realize that our plant material is overgrown and screaming for help. Pruning is an art and I am on a mission to help the gardener/homeowner understand the value of “pruning for health”. The condition of the supporting soil is equally important to the health of the plant.

Restoring a plant to become healthier and sustainable for seasons to come can take a number of pruning over a period of seasons. Neglected plant material generally looses shape with growing occurring on the outer edges preventing any new growth underneath. Proper pruning, consistently scheduled, increases the life expectancy and beauty of the plant.

There are two types of restorative pruning; rejuvenating and renewal.

Rejuvenation pruning is a more radical form of pruning used when the shrubs are overgrown, ugly, dying out in the center and experiencing reduced flowering. This type of pruning should be done in the early spring prior to the emergence of new growth and only done when needed. Note: if the plant flowers early this pruning may be delayed until bloom is finished.

Renewal pruning is less drastic and takes place over the course of 2-3 seasons. Each year about 1/3 of the stems are cut out thus allowing in more light and air.

Once the plant material has been pruned, it may enter into shock. A bit of TLC is required. Proper watering, using good organic fertilizer, adding compost is the best method to ensure prosperity.
