Gardening in colder climates can be challenging, especially when it comes to protecting plants from early frosts. However, a simple and effective solution is to use floating row covers. These lightweight fabrics act as a shield against frost, allowing your plants to thrive and extend your growing season. In this article, we will explore the benefits of using floating row covers and provide you with some handy tips to successfully implement this technique in your garden.

What are Floating Row Covers?

Floating row covers are thin, transparent or semi-transparent fabrics made from materials like lightweight polyester or polypropylene. They are designed to be draped over top of plants and suspended above them using hoops or stakes. The covers create a microclimate around the plants, providing insulation and protection from cold temperatures, frost, wind, and even pests. They allow sunlight, air, and water to penetrate while trapping heat inside, making this technique ideal for protecting delicate plants from early frosts.

The Benefits of Floating Row Covers

Using floating row covers offers several benefits for gardeners, including:

1. Frost Protection

The primary purpose of floating row covers is to protect plants from early frosts, which can damage or kill tender plants. By covering your plants with row covers, you create a barrier that prevents the cold air from reaching them. The fabric traps the heat generated by the soil and the sun during the day, creating a more favorable environment for your plants.

2. Pest Prevention

Floating row covers also act as a physical barrier against pests, such as insects and birds, that may damage your plants. The fabric is tightly woven enough to keep most pests out while allowing air and water to flow through. It's an excellent organic method to control infestations without resorting to harmful pesticides.

3. Increased Soil Warmth

By using row covers, you provide an additional layer of insulation to the soil, keeping it warm for longer periods. This is particularly beneficial for heat-loving plants that require a certain soil temperature to thrive. Moreover, the increased warmth can promote better root development and enable plants to establish themselves more quickly.

4. Extended Growing Season

Floating row covers can extend your growing season since they protect plants from frost. With the covers in place, you can start planting earlier in the spring and prolong your harvest well into the fall. This extended period allows you to enjoy fresh produce for a more extended time, even in regions with shorter growing seasons.

Tips for Using Floating Row Covers

To make the most out of your floating row covers, follow these helpful tips:

1. Choose the Right Material

Select a row cover material appropriate for your garden's needs. Lightweight fabrics (0.45 to 0.55 oz/sq. ft) are ideal for frost protection, while heavier fabrics (0.9 to 1.25 oz/sq. ft) provide additional insulation and can be used for colder climates.

2. Install Supports

Before installing the covers, create a support structure for them. Use arch-shaped hoops made of metal, PVC pipe, or wire. Push them into the ground every few feet along the planting row, ensuring they are securely anchored. Alternatively, use stakes to create a low tunnel effect by driving them into the ground on both sides of your plants.

3. Timing

Be mindful of the weather forecast and install the covers before the temperatures drop near freezing. Monitor the weather regularly, and be prepared to remove covers during warm spells to prevent overheating.

4. Securing the Covers

Secure the covers to the supports using clips, clothespins, or by burying the edges under a thin layer of soil. Ensure the covers are pulled tightly and extend all the way to the ground, leaving no gaps for cold air or pests to enter.

5. Ventilation and Watering

To prevent overheating on sunny days, lift the covers slightly or use clothespins to create small vents for air circulation. Check your plants regularly for moisture and water as needed. Floating row covers are permeable to water, but they can reduce the amount of rainfall reaching your plants.

6. Remove Covers Gradually

As the temperatures rise consistently and the risk of frost has passed, gradually remove the covers during the day while still protecting your plants at night. This gradual acclimation allows plants to adjust to the changing temperatures.


Using floating row covers is an effective and affordable way to protect your plants from early frosts while providing other benefits such as pest control and extending the growing season. By following the tips outlined in this article, you can successfully implement this technique in your garden and enjoy healthier, more productive plants for a longer time. Happy gardening!
