The
winter of 2002-3003 was one of the most severe that we have had
in many year. The severe weather was responsible for extensive damage
to woody shrubs and trees; especially evergreens such as holly,
rhododendron, cherry-laurel and azalea. As the spring progresses,
you will also notice damage to certain deciduous shrubs such as
hydrangeas.
The
fact that many (even well-establlished) plants have been stressed
and weakened by numerous droughts over the last several years compounds
the problem. There are several things that you can do to help rejuvenate
these plants, and get them back on the road to good health.
1.
Be PATIENT even badly winter-burned plants will often make a
remarkable recovery, even if you do nothing more than give them
some time. Often by early summer they will look dramatically better.
They simply need time to push out an initial flush of new leaf-growth.
2.
Analyze just because the leaves of your evergreens might be
badly damaged doesn't mean that your plant is dead or dying! It's
important to check the health of the stems. To do this gently scratch
the surface bark on several of the upper twigs, and check for healthy,
green tissue. Good green color indicated healthy tissue and thus
a good chance for regrowth.
3.
Fertilize the best way for you to help your plants is to give
them a boost of nutrients to help strengthen and re-energize them.
A.
Between January and Mid-April you can use any good quality organic
fertilizer such as Hollytone, Plantone, Milorganite, etc.
B.
Between early April and mid June, you might consider a more quick-release
fertilizer, such as 10-10-10-or 5-10-5.
C.
Another "quick - fix" solution would be to use a water
-soluble fertilizer, such as Miracle-Gro, diluted with water in
a large bucket and slowly poured around the base of the plant. Water-solubles
can also be combined with Superthrive plant stimulant and or Roots
II fertilizer. This solution can quickly help improve the vigor
and health of your plants. This can be applied anytime between April
and mid-June.
D.
You might even consider using techniques both "A" and
"C" for severely damaged or stressed plants.
4.
Prune (mid to late April), dead branches will make themselves
very apparent. Carefully prune out all dead and dying wood to help
reduce the potential spread of diseases and insects.
5.
Monitor occasionally inspect your plants through the growing
season for insect or disease problems. Stressed plants are much
more prone to these problems than healthy specimens. Prompt treatment
of pest and disease problems is crucial.
6. Water as moist as the soil might be from October through
May, it's very important to make sure that your plants are getting
enough water during the dry summer months. Newly installed plants
are very prone to stress caused by lack of water. Even old, well-established
plants can be stressed and severely weakened by drought damage.
This weakness can magnify winter damage, and pest and disease problems.
7.
Spraying
evergreens as well as deciduous plants with an antidessicant such
as 'Wiltpruf' or burlapping sensitive plants are great mehtods for
preventing winter burn. For more details call Young's nurseries
