Loping shears for large branches |
Shrubs
are a valuable part of the landscape, filling the niche intermediate between lawn
and trees. Shrubs are planted for their ornamental characteristics such as flowers,
foliage, fall color, or fruit. Proper pruning by Crabapple LandscapExperts maintains plant health, controls
or shapes plant growth and stimulates flowering.
Many
deciduous shrubs (the ones that lose their leaves in fall plus broadleaf evergreens) can be kept healthy
and vigorous by removing a few of the oldest, thickest stems every couple of
years. If this process is neglected shrubs become leggy and overgrown, and then
rejuvenation pruning is needed.
Botanically
Speaking
A shoot
consists of a stem with a growing tip and leaves. When the growing tip is
removed (pruned) then dormant, lateral buds at the base of each leaf are
stimulated to grow, and the branch becomes more “bushy”. Dormant buds at the
base of the shrub can also begin growth if older branches are removed at ground
level.
Timing
Rejuvenation
pruning is best accomplished while the shrubs are dormant- late fall through
late winter. Consult your Crabpple Rep now for scheduling.
Methods
One
technique used by our Crabapple LandscapExperts is to selectively remove
one-third to one-half of the large overgrown branches from the base of the
plant using long-handled lopers. This stimulates dormant buds to grow,
producing vigorous young branching from the base.
Holly stumps will soon resprout |
A drastic method
we employ with success for hugely-overgrown hollies for example is to cut
them back to 6 inches from the soil using a chain saw (!) on the trunks. This
leaves large unsightly stumps-- but only for 3-4 weeks, until dormant buds
begin to grow. Soon, within 6 to 8 weeks, a beautiful, small young holly
replaces the former encroaching giant. Afterward, arrange for your LandscapExperts to take
care that they are properly pruned and maintained in future.
Conifer
Caution
Large,
overgrown evergreens are a more difficult problem. It is sometimes best to
remove overgrown junipers or arborvitaes and other evergreens that cannot be
pruned back severely because they will never re-grow new shoots. Junipers for
example, have a large dead zone in the center with few dormant buds that cannot
be stimulated to grow. Crabapple techs know never to remove all the greenery
from a juniper branch because no new branches will be initiated from bare wood.
In this case, your LandscapExpert will suggest removal and replanting with
appropriate shrubs.
