Can you use a cold frame to start seedlings?

How do you keep a cold frame warm at night?

A mat or blanket may be placed over the frame on cold nights to conserve heat, but this increases temperature by only a few degrees. There are times, however, when a few degrees can be very important.

What is the best position for a cold frame?

Where is the best place to put a cold frame? To maximize warmth, light exposure, and weather protection for plants, cold frames should be sited in a south-facing position.

When should you plant in a cold frame?

At least two weeks before you sow early vegetables like spinach, radishes or peas in spring, put your cold frame in place. This will help to gently warm the soil within the frame to temperatures that are more suited to growing cool-season vegetables.

Why are my seedlings tall and skinny?

The most common cause of legginess is an insufficient or uneven access to light. When the light source is too dim or distant, seedlings grow quickly in height to get closer to that light. As the seedling gains height, it sacrifices in girth and strength, resulting in thin, pale, fragile, stretched-out stems.

How cold is too cold for seedlings?

Seedlings, with their tender new leaves, often give up the ghost when temperatures dip to 32-33°F. Tropical plants have differing low-temperature thresholds. Some keel over when temps fall to 40°F; others crumble at 35°F. Other plants are just hardy by nature and can withstand temperatures as low as 18-20°F.
