Just the facts
--> Prune spring flowering shrubs after they finish flowering,
usually early May. The new growth added after this spring
pruning contains most of the flowers for next springs show.
Prune enough off in May so the plant will only need light
tipping as it grows back to the desired height during the
summer. Next spring the plant will be covered in flowers.
--> Prune summer flowering shrubs in spring (March) before they
leaf out. The new growth added after this pruning contains
all the flowers for the summer displays.
--> Poke holes into the tops of shrubs you prune or shear a lot.
( Manhattan Euonymus, Privot, Holly, Yew)
Continuously pruning at the same height promotes a thick
mass of new growth at the top of the plant. This thick
area deters sunlight from reaching the interior, causing
branches to die and the plant too become thin and unhealthy.
This area is also cool and shady and becomes the perfect
breeding gound for insects like scale and spider mites.
Poking holes allows sunlight and rain inside, promotes
healthy new interior growth and decreases the build up of
insect populations.
*** How to poke holes. Reach down into the interior of the plant
from the top, about 1/3 to 1/2 way and cut branches back to
another growing point. (where the branch meets another
branch) Depending on size of plant, remove 3-4 clumps every
year. Try to make one cut and remove a large clump or branch
instead of 4 cuts of single branches.
--> Remove any dead in trees and shrubs to increase total curb
appeal.
