What You'll Learn
Protecting plants from frost
Plastic bags can damage plants if they come into contact with foliage as they hold water against the plant, which can freeze. Plastic is also not a very insulating material and does not offer the breathability plants need during cold weather. The bags can easily trap moisture, which can freeze the plant instead of protecting it. Additionally, plastic intensifies the sun's rays, and your plants can quickly go from freezing to burning.
Instead of using plastic bags, opt for materials that provide good insulation and airflow, such as cloth. Frost fabric or row covers are recommended by professional landscape services. You can also use old blankets, towels, and sheets. For young trees, burlap is an easy and affordable option as it is both breathable and durable.
If you decide to use plastic bags, ensure they do not touch the plant. You can use stakes or sticks to keep the plastic from making contact. Poke small pinholes in the plastic to help with air circulation. Make sure to remove the plastic bags early in the morning, especially if the sun is shining, to prevent your plants from burning.
Other methods to protect your plants from frost include using cloches, which are bell-shaped covers made from glass or plastic. You can buy these or make your own by cutting off the tops of large plastic bottles or milk containers. Remember to remove cloches or plastic coverings during the day to allow your plants to benefit from the sun's warmth.

Protection from pests and disease
Covering flowers and plants with plastic bags can help protect them from pests and diseases. This method creates a mini-ecosystem, where the plant recycles nutrients and moisture. However, it is important to note that the environment becomes conducive to pests and diseases if they are already present.
To effectively use plastic bags for protection, follow these steps:
- Ensure your plants are healthy by checking the roots for any signs of rot or disease.
- Remove dead leaves and treat pests if necessary.
- Water your plants a couple of days before covering them in plastic. This ensures the soil is moist but not soggy.
- Use chopsticks or similar sticks to keep the plastic from touching the foliage.
- Place the plastic bag over the plant, securing it with tape or tying the ends together.
- Remove the plastic bag after a couple of weeks to prevent mould growth and provide fresh air.
- Prick small pinholes in the plastic to improve air circulation while maintaining moisture.
While plastic bags offer protection, they can also pose risks. Plastic intensifies the sun's rays, and plants can quickly go from freezing to burning. Therefore, it is crucial to place plants in shady spots and remove the plastic bags early in the day if the sun is shining. Additionally, ensure adequate air circulation to avoid damping off.
An alternative to plastic bags is mesh bags, which are effective barriers against pests. They are reusable, inexpensive, and environmentally friendly as they do not involve the use of pesticides, which can harm beneficial insects such as bees. Mesh bags are particularly useful for protecting against insects, squirrels, rabbits, deer, and birds.

Maintaining moisture
First, ensure your plants are well-watered before you leave. This provides a good base level of moisture for your plants to draw upon. You can further enhance moisture retention by employing the plastic bag technique.
Select an appropriately sized plastic bag for your plant. For smaller plants, a regular plastic bag should suffice, while larger plants may require a plastic garbage bag or tarp. Place the bag over the plant, ensuring it covers the entire plant, including the pot. For smaller plants, you can tie the bag at the top, while for larger plants, you may need to tape the bag to the sides or bottom of the pot.
To maintain moisture, you should completely seal the plastic bag to prevent moisture from evaporating. However, it is crucial to provide adequate air circulation to avoid damping off. Remove the plastic bag for about an hour every few days to allow the plant to breathe and check the soil moisture levels. Pricking small pinholes in the plastic can also help with air circulation while retaining moisture.
Additionally, be cautious of excessive condensation, as it can promote fungal growth. Ensure the plastic bag is not in direct contact with the plant's leaves, and periodically check for any signs of fungal or pest issues. If you notice excess moisture or condensation, remove the bag and allow the plant to dry out slightly before replacing the cover.
By following these steps, you can effectively use plastic bags to maintain moisture for your flowers and plants, ensuring they remain healthy and thriving, even in your absence.

Avoiding excessive moisture
Covering plants with plastic bags can help maintain moisture, particularly when you are away from home for several weeks or are sprouting small seeds that need to remain constantly moist. However, it is important to avoid excessive moisture to prevent the growth of disease organisms such as Botrytis (grey mold). Here are some tips to avoid excessive moisture when using plastic bags to cover flowers:
- Ensure your plants are moist but not soggy before enclosing them in plastic. Give excess water time to evaporate or run out of the container.
- Prick small pinholes in the plastic to aid with air circulation while still providing the necessary moisture for growth.
- Do not leave plants covered for extended periods without periodically removing the plastic bag. For example, if using a plastic bag to cover sprouting seeds, allow them to get brief peeks of sun and remove the plastic bag for an hour or so every few days.
- Place the covered plants in a shady spot, especially if they must be left covered for a long time. Plastic intensifies the sun's rays, and your plants can quickly go from the risk of freezing to burning.
- Avoid placing covered plants near sources of ethylene-producing substances, such as ripening fruits, gasoline, or propane combustion. Ethylene gas can damage flowers even in very small amounts.
- Use a fan to improve air circulation for plants covered in plastic.
By following these guidelines, you can help prevent excessive moisture and create optimal conditions for your flowers when using plastic bags as a covering.

Creating a greenhouse
Covering flowers with plastic bags can help keep them moist, but it can also lead to burning if not carefully managed. This method is a simple way to create a miniature greenhouse effect, which can be beneficial for small plants and seeds.
Building a greenhouse is a great way to cultivate a variety of plants year-round. There are several steps to creating a functional and effective greenhouse.
First, you must choose a location. It is important to select a sunny spot with access to electricity and well-drained soil. Face the greenhouse south or southeast to maximize sun exposure. If you're converting an existing structure, you can skip this step.
Next, decide whether to purchase a greenhouse kit or build the frame yourself. Kits are recommended for first-time builders. If you're converting a structure, ensure you have a rigid frame to work with.
Once you have your frame, it's time to add the covering. You can use hard, double-walled plastic or clear fiberglass to trap sunlight effectively. Glass is an option, but it is fragile and expensive. Polyethylene plastics are lightweight and cheap but less durable and may contain BPA, which is unsafe for growing food. Acrylic (Plexiglass) is a non-toxic option that lets more light through but is pricier and less durable.
After the covering is in place, add fans and vents to control airflow and temperature. Install a thermostat to regulate temperature and consider an electric heater for colder months.
Finally, it's time to add plants! You can build shelves or raised beds inside the greenhouse to optimize space and drainage. Ensure a steady water supply, preferably via hose water and cisterns.
With these steps, you can create a functional greenhouse to nurture a variety of plants.
