Marietta Daisies Garden Club Winter Damage Plants

Cold Weather Damaged Plants

Our gardens are showing plant damage from the 10 day, single digit temperatures.

According to our

local nursery

Autumn Hill,

the best thing to do is nothing quite yet.

It is too soon to tell if the extended deep freeze just killed the leaves, or possibly some branches or whether the entire plant has met it's demise.

Dead leaves will often remain on the plant until new growth emerges pushing the old

leaves off. Depending on the weather and type of plant we may see signs of new growth

as early as mid March or a late as May. Dead branches may eventually turn black or mushy. Most will become brittle and the cambium layer beneath the bark will turn brown rather than greenish yellow.

Scratching the bark with your fingernail or pocket knife will expose the cambium layer.

This brittleness and browning of the cambium layer can take weeks to appear.

Once you do see dead branches you can prune them off, but keep in mind it still may be too soon to tell if the entire plant is dead or if it will grow back from the base.

Hydrangeas come to mind here. Often all their branches will succumb to stress from the cold, but grow back quite nicely from the base. Be patient, and give your plants time to tell you if they will recover. I know it can be unsightly to look at brown leaves, but we may be pleasantly surprised by what comes back.
