Winter Damage :
Prevention and repair
There are various reasons for winter damage. To address just
a few, I will write about damage due to cold, snow, ice, salt
& pests.
I am sure that each of you will recognize some of these problems.
Using the right prevention technique can eliminate most winter
damages.

Most common winter damages are related to cold.
All plants in your garden should be suitable for the hardiness
zone of your area. Any plants that are growing in a challenging
location should be preferably hardier than your zone and suitable
for the location depending on the nature of the challenge.
For example, shade, full sun, wind, plant competition or moisture
in the soil could be challenging factors. Tender plants can
be protected by mulching, which is simply creating a mound
of composting material around the base of the plant. Commonly
used mulching materials are leaves, compost, peat moss and
straw. In the fall, plants need to be "hardened off"
which means to gradually allow them to get used to cold temperatures
so that they build up resistance. Therefore, we should time
mulching accordingly. In the Spring, gardeners leave their
tender plants mulched for too long and that can lead to unwanted
tender growth under the mulch. If foliage on evergreens has
brown spots due to cold weather simply remove the damaged
leaves.

Heavy snow and ice can break branches and open
up the shrub so that it resembles an old broom more than a
symmetrical bush. Again, location is the first factor we should
take into consideration. Snow falling from the roof can break
branches of shrubs beyond repair. Also planning where to put
excess snow from your driveway and paths would be worth some
consideration. In addition, if moist snow freezes it becomes
heavy and permanently stuck to branches until it gets warm
again. Simply shaking the wet snow of bending branches can
prevent most damage. If you find broken branches in the spring,
you can cut them off and treat them with a latex-based product
with growing hormones such as Heal and Seal.
Over-use of salt is another cause of winter
damage. Try to avoid the use of salt close to your flowerbeds.
If some areas become saturated you can try to pour water over
the affected area to dilute the salt.
Many animals like to visit gardens, mostly in late winter,
to feed on the plants. Best prevention is to plant plants
that are not on their menu list, like poisons or prickly plants.
Another is to build a solid fence.
Overall, most winter damage can be prevented by careful planning
and a little bit of maintenance. Well-planned landscaping
will minimize your amount of winter preparation.
