Gardening can be a rewarding experience, but the unpredictability of weather can sometimes pose a challenge. Late frosts are one such hurdle that can damage or kill tender plants, hampering the efforts of gardeners. However, with the use of covers, you can protect your plants from late frosts and ensure they thrive. In this article, we will explore this gardening tip in detail.

Understanding Late Frosts

Before we delve into the protective measures, it’s important to understand what a late frost is and how it can affect your plants. Late frosts typically occur during spring when the weather starts to warm up, but occasional cold snaps still take place. These frigid temperatures can harm delicate plants and buds, stunting growth or causing them to wither.

Choosing the Right Covers

When it comes to protecting your plants from late frosts, choosing the right covers is essential. Here are a few options you can consider:

1. Frost Blankets

Frost blankets are made from lightweight, breathable fabric that allows air and moisture to pass through while protecting plants from frost. They are available in various sizes and can be draped over individual plants or used to cover entire rows in a garden. Frost blankets are an excellent option for plants that need airflow, such as leafy greens and herbaceous perennials.

2. Plastic Sheeting

Plastic sheeting can be an affordable and effective option for protecting plants from late frosts. However, it's crucial to ensure that the plastic doesn't touch the foliage of the plants, as direct contact can cause damage. Create a frame using stakes or hoops to keep the plastic away from the plants and provide better insulation. Plastic sheeting is particularly useful for covering larger areas or plants that require a slightly warmer environment.

3. Cloches

Cloches are individual protective covers that can be placed over young or delicate plants. They are typically made of glass, plastic, or even inverted buckets. Cloches work by trapping heat from the sun during the day and retaining it at night, creating a microclimate for the plants. While they provide excellent protection, it’s important to open or remove the cloches during the day to prevent excessive heat buildup.

When to Apply the Covers

Knowing when to apply the covers is vital for their effectiveness. Here are a few guidelines to keep in mind:

1. Check Weather Forecasts

Paying attention to weather forecasts is crucial when it comes to protecting your plants. Keep an eye out for predicted late frost events and be prepared to cover your plants accordingly. By knowing when a frost is likely, you can be proactive in safeguarding your garden.

2. Evening Application

Applying the covers in the evening when temperatures start to drop is generally recommended. By doing so, you ensure that your plants have adequate protection during the coldest part of the night when frost is more likely to set in. Remember to remove the covers in the morning once temperatures rise above freezing to prevent overheating and potential damage.

3. Prioritize Vulnerable Plants

While covering all your plants can be beneficial, it may not always be practical or necessary. Prioritize your more vulnerable plants, such as young seedlings, recently transplanted flowers, or sensitive crops. By focusing on these plants, you can maximize the effectiveness of the covers and save yourself time and effort.


Protecting your plants from late frosts is crucial for maintaining a healthy and thriving garden. By utilizing covers such as frost blankets, plastic sheeting, or cloches, you provide an extra layer of insulation against the cold. Remember to choose the appropriate covers for your plants, apply them at the right time, and prioritize the most vulnerable plants for optimal results. With these precautions, you can protect your garden from late frosts and enjoy a beautiful and bountiful harvest.
