Protecting Balcony Plants in Winter

As the frosty winter breeze sweeps through, your balcony plants might be shivering off their lush green coats. But fret not; with a tad bit of care, you can shield them from the chilly wrath. Here’s your handy guide on keeping those greens warm and snug.

Insulation Techniques:

Your plants need a warm blanket, too well! Here’s how you can insulate them.

  1. Bubble Wrap: This isn’t just for popping; wrap it around your pots to keep the soil warm.
  2. Fleece: A layer of garden fleece can be a soft, warm hug for your plants.
  3. Mulch: A thick layer of mulch on the soil surface can keep the cold at bay.
  4. Insulated Plant Covers: They are like cozy sleeping bags for your plants.

Using Other Materials:

Get creative and use what you have to keep the chill-out.

  1. Old Blankets or Burlap: Wrap them around your pots to add an extra layer of warmth.
  2. Straw or Leaves: Pack them around your plants to trap heat.
  3. Styrofoam: Create a Styrofoam shield around your plants; it’s a great insulator.


Where your plants sit can make a big difference in how warm they stay.

  1. Sunny Spot: Move your plants to where they can soak up the most sun during the day.
  2. Group Together: Put your plants close together to create a microclimate.
  3. Indoor Vacay: Bring them indoors during extremely cold days or nights.
  4. Against the Wall: Place them near walls to get reflected heat and shelter from wind.

Other Warm-up Acts:

  1. Water Wisely: Water your plants with lukewarm water to prevent shocking their roots.
  2. Windbreaks: Install temporary windbreaks to block the cold winds from reaching your plants.

Materials for Winter Greenhouses 

Just like you need a warm coat greenhouse in winter, your balcony greenhouse for winter needs the right cover to keep your plants cozy. The right material will help keep the cold out and let the sun in. Here’s a look at some materials you could choose from for your greenhouse:

Best Materials for Winter Greenhouses:

Polycarbonate Panels:

  • Twin-wall:Imagine a sandwich, but instead of meat or cheese in the middle, there’s air. This design helps to keep the warmth in and is not too expensive.
  • Triple-wall:This one has two layers of air, making it even warmer but a bit more pricey.


  • Single-pane:This is just a single sheet of glass. It’s clear and nice but doesn’t keep the heat in very well.
  • Double-pane:This has two sheets of glass with air in between. It’s better at keeping your plants warm but is heavier and costs more.

Polyethylene Film:

  • Single-layer:This is a thin plastic cover that is easy on the pocket but could be better at keeping the warmth in.
  • Double-layer:With an extra layer, this type keeps the warmth in better but costs a little more.

Comparing the Materials:

Let’s see how these materials stack up against each other in terms of keeping warmth in, lasting a long time, and cost.

Keeping Warmth In:

  • The Warmest:The triple-wall polycarbonate is the warmest, followed by double-pane glass and then double-layer polyethylene.

Lasting a Long Time:

  • The Longest:Glass lasts the longest, followed by polycarbonate. Polyethylene doesn’t last as long because it can get damaged more easily.


  • The Cheapest:The single-layer polyethylene is the cheapest, followed by single-pane glass and single-wall polycarbonate.

Extending to Patio Greenhouses
