Frost poses a significant threat to crops and agricultural yields. Unlike sunny days when warmth sustains life, frost brings a chill that can wreak havoc on delicate plants. This happens when temperatures drop below the freezing point, causing the moisture in the air to condense and freeze on surfaces. This frozen moisture forms a layer of ice, commonly known as frost, which blankets the ground and vegetation.
How frost affects plants varies depending on factors like:
- The duration and intensity of the frost event
- The stage of growth of the crops
- The type of crop being cultivated
Generally, frost can cause cellular damage to plant tissues, disrupting vital physiological processes essential for growth and development. This damage can manifest in various ways, such as wilting, browning of leaves, and even the death of plant tissues.
Frost can also have long-lasting consequences beyond immediate crop damage. It can delay planting schedules, reduce crop yields, and ultimately affect food security and economic stability in agricultural regions. Additionally, frost events may be influenced by climatic factors such as changes in temperature patterns and the frequency of extreme weather events, further complicating the challenge of mitigating its impact on agriculture.
Because frost is harmful to plants, it’s important to work out strategies to protect your garden from extreme cold temperatures. One of the best and most practical ways to do this is to use burlap as plant covers.

What Makes Burlap a Great Plant Cover?
Burlap, a coarse, woven fabric made from natural fibers, offers a range of benefits that make it well-suited for shielding plants from various environmental stressors, especially extreme cold. In fact, burlap is often used as a shield from frost and snow during the winter season.
Provides Insulation
Burlap covers provide insulation, which helps regulate temperature and protect plants from extreme cold or heat. Rapid temperature fluctuations can harm delicate plant tissues. When draped over plants, burlap traps a layer of air around them, acting as a buffer against sudden temperature changes.
During cold weather, burlap covers can help retain heat around plants, preventing the cold from reaching the plants and protecting them from frostbite. This reduces the risk of frost damage.
Also, the soil absorbs warmth from the sun during the day. At night, burlap covers prevent this warmth from escaping into the cold air, keeping the soil and, consequently, the plants warmer for longer periods.
Burlap Covers Offer Protection from Icy Winds
Strong winds and chilly gusts can strip moisture from plants and cause physical damage by bending or breaking their stems and branches. It can also cause the same damage as frost, causing plants to become brittle and break easily.
Burlap helps block winter winds, minimizing the effect on plants while also trapping heat. By blocking the wind, burlap helps maintain a more stable environment around the plants, reducing the risk of frost damage.
When frost forms, it’s often because of moisture in the air freezing on the plants. Burlap covers prevent this moisture from directly landing on the plants, keeping them dry and safe from the icy grasp of frost.
Retain Moisture
It’s a challenge to water plants in the dead of winter. Thankfully, burlap cover has the ability to conserve moisture in the soil. How? It prevents evaporation, so plants don’t need frequent watering.
By reducing evaporation, burlap covers help retain moisture around plant roots, ensuring adequate hydration, especially during dry periods. By preserving soil moisture, burlap covers support healthy plant growth and minimize the risk of stress.
Also, the burlap material is breathable. This prevents moisture from building up, which can lead to fungal growth and other problems. Burlap covers strike a balance between protection and ventilation, creating a healthy environment for plants to thrive in.
Lightweight and Practical
Burlap covers are lightweight and flexible, making them easy to handle and install over plants of various sizes and shapes.
Rigid materials, such as plastic or metal, do not conform to the contours of plants. This can be problematic in the winter when strong winds and icy rains occur frequently. The rigidness of the material can either restrict growth or cause damage to plant stems.
Because burlap covers are easy to install, you can cover individual plants or entire garden beds, providing comprehensive protection against environmental threats. The material is also cost-effective and readily available, making it accessible to both small-scale gardeners and commercial growers.
Effective Sun Protection
Winter doesn’t mean zero sunlight. In fact, many plants remain vulnerable to sunburn despite the frosty weather. Unless you are checking your plants regularly, it’s hard to tell which plants are being damaged by intense sunlight.
Additionally, prolonged exposure to direct sunlight can lead to dehydration in plants, and combined with harsh weather conditions, sensitive plants are extra vulnerable to the elements.
Burlap covers create a shaded environment, shielding plants from excessive sunlight and preventing sun-related damage.
How to Maintain Burlap Covers in Winter
Maintaining burlap plant covers during frosty weather is crucial to ensure they continue to provide effective protection for your plants. Here are some simple steps to keep your burlap covers in good condition:
Check for damage: Before frosty weather arrives, inspect your burlap covers for any tears, holes, or signs of wear and tear. Repair any damage promptly to prevent cold air from seeping through and reaching your plants.
Secure the covers: Make sure your burlap covers are securely anchored in place to prevent them from blowing away in strong winds. Use garden stakes or heavy objects to weigh down the edges of the covers and keep them firmly in place.
Monitor moisture levels: Check the moisture levels around your plants regularly, especially if you’ve covered them with burlap. While burlap helps retain moisture, excessive wetness can promote fungal growth and damage your plants. If the weather is particularly damp, consider removing the covers temporarily to allow the soil to dry out slightly.
Ventilate when necessary: While burlap covers provide insulation, it’s essential to allow airflow around your plants to prevent overheating and humidity buildup. On sunny days, consider partially removing the covers or propping them up to allow air circulation. Be sure to cover the plants again before nighttime temperatures drop.
Remove snow buildup: If snow accumulates on your burlap covers during frosty weather, gently brush it off to prevent the weight of the snow from damaging the covers or crushing your plants underneath. Use a soft brush or broom to remove the snow carefully without causing any damage.
Monitor plant health: Keep an eye on the condition of your plants while they’re covered with burlap. Check for any signs of frost damage, such as wilting or discoloration, and take appropriate action if necessary. Remove any damaged or dead plant parts to encourage healthy growth once the frost has passed.
Remove covers gradually: As the weather starts to warm up and the risk of frost diminishes, gradually remove the burlap covers from your plants. Start by uncovering them during the daytime when temperatures are milder, then gradually leave them uncovered for longer periods until you no longer need them.
