From the high 60s to snow and low 30s back to the upper 70s, the weather has been all over the map so far and we should be prepared for more of the same from the often-moody month of March.
Why Spring freezes are so damaging. Spring cold snaps are common. Warm spells in March can push plants out of dormancy, making new growth extremely vulnerable. Frost can form even in the mid‑30s°F as moisture freezes on plant surfaces. Ice crystals can rupture plant cells, causing blackened, wilted foliage.
What to do when a freeze is in the forecast:
-Water the soil (not the leaves). Moist soil retains heat better than dry soil.
-Cover plants with breathable materials. Use blankets, sheets, burlap, or frost cloth—never plastic, directly on plants. Secure edges to trap ground heat. Remove covers in the morning to prevent overheating.
-Bring containers Indoors. Potted plants are more vulnerable because roots are exposed to cold air on all sides.
Once the weather warms up, it's important to not prune right away. Damaged leaves can protect healthy tissue underneath. Wait a few days to assess new growth before removing dead material.
The good news is that you can still plant. St Patrick’s Day is coming.
Time to plant potatoes, followed by onions.
It’s a good time to be starting your pepper and tomato seeds indoors.
As for adding color to the perennial garden,
Hellebores are in bloom, as well as violas.
They’re outside, fully acclimated, ready to take home,
as is Forsythia, Rock Cress and Heuchera.
Just be ready for the next turn in the weather.
