What to Cover Tomato Plants With

Tomato plants are a popular addition to any garden. However, growing tomatoes can be challenging due to various pests, fungi, and diseases that can ruin the crop. One way to protect your tomato plants is by covering them with the right material. Here, we’ll discuss the different materials you can use to cover your tomato plants and their pros and cons.

1. Row Covers

Row covers are a thin, lightweight, and permeable fabric made of polyester or polypropylene. These covers are designed to increase plant growth and protect against pests, such as aphids, whiteflies, and leaf miners. Row covers also help prevent temperature fluctuations, which can stunt the growth of the tomato plants.

However, row covers have some downsides. The lightweight fabric is not durable, so it may rip or tear easily. The covers must be removed when the tomato plant blossoms, as they can interfere with pollination.

2. Polycarbonate Panels

Polycarbonate panels are a popular option for greenhouses, but they can also be used to cover tomato plants. These panels are made of clear, durable plastic that provides excellent protection against pests and inclement weather. Polycarbonate panels also help to trap heat and create a warm microclimate, which is beneficial for tomato growth.

The downside of polycarbonate panels is that they are more expensive than other options. Additionally, they require a sturdy frame to support their weight, which can be difficult to install.

3. Shade Cloth

Shade cloth is a versatile material that can be used to protect tomato plants from the sun and excessive heat. Shade cloth is made of woven polypropylene and comes in various densities, which determine the amount of light that penetrates the cover. The optimal density for tomato plants is 30-50%, which allows for partial sun exposure while protecting against heat stress.

The downside of shade cloth is that it does not provide protection against pests or inclement weather. Additionally, it may require additional support to prevent sagging due to heavy rain or snow.

4. Plastic Film

Plastic film is a cheap and readily available option for covering tomato plants. It can provide protection against pests, retain moisture, and increase soil temperature. However, plastic film can cause problems with air circulation, leading to excessive moisture and fungal growth. It also does not provide protection against cold temperatures.

Using plastic film for covering tomato plants should be a temporary solution, as it is not a long-term option. It is best used for an early-season boost before the tomato plants reach maturity and require more permanent protection.

Conclusion

The right material to cover tomato plants depends on your specific needs and growing conditions. Row covers are lightweight and permeable, but they can be easily damaged and may interfere with pollination. Polycarbonate panels provide excellent protection, but they are more expensive and require a sturdy frame. Shade cloth is a versatile option that protects against excess sun and heat stress but does not provide pest or weather protection. And finally, plastic film is a temporary and cheap solution that retains moisture and increases soil temperature but does not provide long-term protection.

Consider your budget, growing conditions, and specific needs before choosing the material to cover your tomato plants with. With the right protection in place, you’ll be able to enjoy a bountiful harvest of fresh, delicious tomatoes.
