Don't Let One Cold Night Win — How to Cover Your Plants

It only takes one cold night to undo a lot of good work. The fix? Simple. Cover your plants — just make sure you're using the right materials.

Here's What Works

The goal is simple: trap heat without crushing the plant.

  • Frost Cloth / Row Cover: The gold standard. Lightweight, breathable, and designed for this exact job. Best protection without overheating.
  • Old Sheets or Light Blankets: Easy and effective. Most people already have them. Just keep them off the foliage if possible.
  • Cardboard Boxes: Perfect for quick overnight protection on small plants. Trap heat well — remove in the morning.
  • Upside-Down Pots or Totes: Great for individual plants or patio containers. Simple. Fast. Works in a pinch.

Skip These

Plastic (by itself). Seems like a good idea, until it's not. Plastic traps moisture and cold against the leaves and can actually make damage worse. If you use plastic, layer it over fabric — not directly on the plant.

Pro Tip (from the growers)

  • Cover before sunset to trap the day's warmth.
  • Uncover in the morning once temps rise.

That little bit of timing? Makes all the difference.

Hoosier Tip

Keep a frost cloth on hand from late April through Mother's Day. One $15 cover from a local garden center will save you from replanting an entire container.
