Even a light frost can damage or kill tender plants, especially those in containers. Pots lose heat faster than the ground, leaving roots and foliage exposed. A simple cover can make all the difference, trapping warmth and shielding plants from icy air.

𝟏. 𝐎𝐥𝐝 𝐁𝐞𝐝𝐬𝐡𝐞𝐞𝐭𝐬 & 𝐁𝐥𝐚𝐧𝐤𝐞𝐭𝐬

That spare sheet in your linen closet? Perfect for draping over your pots on frosty nights. Lightweight cotton allows airflow while keeping warmth close. Secure with clothespins or garden clips so the wind doesn’t whip it away.

𝟐. 𝐓𝐨𝐰𝐞𝐥𝐬 𝐨𝐫 𝐓𝐚𝐛𝐥𝐞𝐜𝐥𝐨𝐭𝐡𝐬

Thicker fabric adds extra insulation for colder nights. Drape carefully to avoid crushing delicate stems. For taller plants, create a “tent” using stakes or tomato cages to keep fabric off the foliage.

𝟑. 𝐂𝐚𝐫𝐝𝐛𝐨𝐚𝐫𝐝 𝐁𝐨𝐱𝐞𝐬

Large boxes make instant mini greenhouses! Flip one over your container, and it’ll trap warmth overnight. Just remember to remove it once the sun rises so your plants don’t overheat.

𝟒. 𝐏𝐥𝐚𝐬𝐭𝐢𝐜 𝐒𝐭𝐨𝐫𝐚𝐠𝐞 𝐁𝐢𝐧𝐬 𝐨𝐫 𝐁𝐮𝐜𝐤𝐞𝐭𝐬

For small pots, plastic tubs or even 5-gallon buckets work wonders. Place them upside down over plants before sunset and lift them in the morning. (Avoid letting plastic touch leaves directly if frost is expected to be heavy.)

𝟓. 𝐑𝐞𝐜𝐲𝐜𝐥𝐞𝐝 𝐁𝐨𝐭𝐭𝐥𝐞𝐬 𝐨𝐫 𝐉𝐮𝐠𝐬

Cut the bottoms off milk jugs or 2-liter soda bottles and pop them over tender seedlings. They act like individual plant domes — simple, reusable, and surprisingly effective.

𝟔. 𝐎𝐥𝐝 𝐂𝐮𝐫𝐭𝐚𝐢𝐧𝐬 𝐨𝐫 𝐒𝐡𝐨𝐰𝐞𝐫 𝐋𝐢𝐧𝐞𝐫𝐬

Water-resistant and easy to drape, these work beautifully during surprise frosts. Pair them with a layer of cloth underneath for better insulation.

Before covering, water your containers in the late afternoon. Moist soil retains heat longer than dry soil. You can also tuck a few rocks inside the pot, they’ll absorb warmth during the day and release it slowly overnight.

Once the sun rises and temperatures climb, uncover your plants so they can breathe and soak up the light. Leaving covers on too long can trap moisture and invite disease.
