First Aid for Freeze Damage
You know you are a true gardener when you are willing to use your own bed
sheets to protect your favorite plants!
Even though this winter was predicted to be mild, we've already seen some
pretty cold temperatures. Even with protection, some of your plants were probably damaged in the
cold. If you are trying to figure out what to do now, see the tips
below. As the first tip says, the best thing to do is to be patient.
1. Be Patient
- This is the hardest part of dealing with winter damage. There is no pruning
allowed until we are past any risk of frost or freeze. The damaged foliage will serve as an insulating layer if more cold weather comes through. We usually start
pruning around the first week of March.
The only exception to this rule is if a plant is truly dead or if parts of
a plant or palm are rotting. In that case, remove the plant or damaged areas from the
garden to avoid spreading disease.
2. Don't Fertilize
- Fertilizer may stimulate growth on plants, but if we get cold again that tender new
growth will be extremely sensitive to the cold. Even cold hardy plants should not typically be fertilized this time of year. At the start of
spring, give everything a good prune and a dose of fertilizer to stimulate a wonderful burst of new growth.
3. Plan your Spring Garden
-
As you drive around town. you may see a palm or shrub completely frost-burnt in one yard,
but look perfectly green in another, even in houses on the same street.
Surprisingly, the temperature around the area varies widely depending on a
number of factors, including the direction a house faces and the number of
trees. Take a look at your own garden and see which spots were warmest and
which were coldest. Plan accordingly for the spring and you'll be able to pick which plants are
likely to perform best for each spot in your garden.
4. Damaged Palms
- For palm trees that sustained some cold damage, the same tip applies - have patience. When you
do prune your palm trees, try to prune only damaged fronds off. Over-pruning a palm tree by removing all fronds can hurt its ability to gather nutrients and limit its
chances of surviving. Leave as much green as possible, or if there aren't any green fronds, prune about half of the damaged ones off and wait for a new frond to grow in the spring
before pruning off the remainder of the old fronds.
5.
Protect from Disease
-
While the freezing temperatures damage the plant, it is usually disease that
actually causes them to die. To keep diseases at bay, especially on damaged
palms, spray a copper fungicide mixed with a spreader sticker every 10 days
or so. This will help the plants fight off disease until they can take over
on their own again.
