If you love gardening, you know how exciting it is to start new plants from cuttings. But when cold weather rolls in, keeping those tender cuttings alive can be a challenge. That’s where a cold frame comes into play — a simple, inexpensive structure that protects your plants from frost while letting in sunlight.
Overwintering your cuttings in a cold frame gives them the shelter they need to survive chilly months and be ready to grow strong next spring. But doing it the right way makes all the difference.
Why Overwinter Cuttings in a Cold Frame?
Many gardeners underestimate how fragile young cuttings can be during winter. Without protection, freezing temperatures, frost, and chilling winds can easily damage or kill them. A cold frame traps solar energy and helps moderate temperature swings — giving your cuttings a much better chance of survival.
If you want a step‑by‑step guide to protecting your cuttings through the cold season, check out this in‑depth article on what is the key to successfully overwintering your cuttings in a simple cold frame: complete cold frame overwintering guide.
How a Cold Frame Works
A cold frame is essentially a miniature greenhouse — usually made with a wooden box and a transparent lid (like old windows or clear plastic). It captures heat from the sun and keeps wind and frost out.
Here’s how it helps:
-
Maintains warmer soil temperatures than the surrounding air
-
Protects plants from frost and wind damage
-
Extends your growing season into fall and winter
Preparing Cuttings for Winter
Before placing cuttings in your cold frame, consider these best practices:
-
Harden off your cuttings: Gradually introduce them to cooler outdoor temperatures over a week or two.
-
Choose healthy, disease‑free cuttings: Weaker cuttings won’t survive winter stress as well.
-
Use well‑draining soil: Moisture control is key — soggy conditions can lead to rot.

Monitoring and Care Through Winter
A cold frame isn’t “set and forget” — you’ll still need to check on your plants:
-
Ventilate on sunny days: Open the lid slightly to prevent overheating.
-
Protect from freezing nights: Close it securely before dusk when temperatures drop.
-
Watch moisture levels: Water sparingly — only when the soil dries out slightly.
Final Thoughts
Using a cold frame to overwinter cuttings is one of the best ways to stretch your gardening season and preserve valuable plants for years to come. With the right preparation and care, your cuttings will stay safe through winter and be ready for vigorous growth in spring.
