In most cases, we use bubble wrap to protect items against impacts, scratches and shocks. It is often used when packing glass, ceramics, electronics and furniture to provide them with an additional layer of protection. Interestingly, it is also used in gardening.
Bubble foil is a material filled with tiny air bubbles that act as a natural thermal insulator. Thanks to its structure, it protects plants against frost, limiting sudden temperature fluctuations and preventing delicate plant parts from freezing. Unlike agrotextiles, bubble wrap is often already in our homes, which makes it an ecological and economical solution.
This material is particularly suitable for: plants sensitive to frost – such as hydrangeas, magnolias, rhododendrons and young roses. It can also be used for potted plantsthat winter on balconies or terraces. By wrapping pots and green parts with foil, we reduce the risk of frost.
If you want to effectively protect your plants against winter, start by preparing them. Remove dry leaves and wilted flowers and check whether the plant is healthy. The day before, water it lightly to ensure the appropriate level of moisture, but avoid overwatering, which could encourage rotting under the foil. Cut the bubble wrap to the appropriate sizeremembering that the bubbles should face the plant.
When wrapping the plant, start from the pot, paying special attention to the roots – you can additionally cover the ground with mulch, e.g. bark or straw. Then gently wrap the above-ground parts of the plant, without tightening the foil too tightly, to allow air to circulate freely. Secure the foil with string or elastic bands, taking care not to damage the shoots.
Check the cover regularly during the winter, especially after severe frost or snowfall. On warmer days, open the foil, to prevent moisture condensation. In spring, remove the covers gradually so that the plant can get used to the temperature changes. Leaving it too long may lead to overheating of the plants and accumulation of moisture, which favors the development of fungi and mold.
Frost protection is not the only use of bubble wrap in the garden. It turns out that it is an effective barrier against pests such as water voles and voles that destroy the root systems of plants. How to protect flowerbeds and vegetable gardens?

Place bubble wrap around the flower beds as a barrier. For greater effectiveness, the foil can be buried a few centimeters in the ground, so that pests cannot get past it. You can also use it to protect flower bulbs. Just place the bulbs in perforated bubble wrap bags before planting them in the ground.
The use of bubble wrap in the garden is also a nod to ecology. Instead of throwing away this material after receiving the shipment, you can give it a second life. It’s a practical way to reduce waste and support your garden at the same time.
If you don’t have bubble wrap, consider using other insulating materials such as:
- old blankets,
- corrugated cardboard,
- jute bags.
These solutions will also help protect your plants from the cold, although they may be less effective against pests.
