Understanding Row Covers and Their Pest Protection Benefits
Protect your plants from pests with this durable garden netting. The ultra-fine mesh allows sunlight, rain, and air to pass through, promoting healthy growth and improved yields.
Row covers create a physical barrier between your crops and the insects that want to devour them. They’re your first line of defense in integrated pest management.
What Are Row Covers and How They Work
Row covers are lightweight fabrics or materials that create a protective tunnel over your plants. They allow sunlight, air, and water to reach your crops while blocking flying and crawling pests.
The material sits directly on plants or over hoops, creating an enclosed microenvironment. This barrier method stops pest lifecycles before they can establish in your garden beds.
Types of Pests Row Covers Protect Against
Row covers effectively block flying insects like cabbage moths, cucumber beetles, and flea beetles from reaching your plants. They also deter larger pests including birds, rabbits, and deer from accessing your crops.
Crawling insects like squash bugs and aphids struggle to penetrate properly installed covers. The physical barrier disrupts their ability to locate and colonize host plants.
Key Features to Look for in Quality Row Covers
Fabric weight determines both protection level and plant growth conditions underneath. Lightweight covers (0.5-0.9 oz) offer pest protection while maintaining optimal growing temperatures for heat-sensitive crops.
UV resistance ensures your investment lasts multiple seasons without degrading. Look for reinforced edges and tear-resistant materials that withstand wind and handling during installation and removal.

Installation and Maintenance Tips
Install the AG-19 by draping it loosely over your crops and securing edges with sandbags or ground staples. You’ll need to check weekly for tears and remove any debris that accumulates on the surface. The cover lasts 3-4 seasons with proper care, making it a cost-effective long-term investment for pest management.

Frequently Asked Questions
What are row covers and how do they protect plants?
Row covers are lightweight fabrics that create a physical barrier between crops and pests while allowing sunlight, air, and water to reach plants. They effectively block flying insects like cabbage moths, cucumber beetles, aphids, and whiteflies, as well as larger pests such as birds and rabbits. Row covers serve as the first line of defense in integrated pest management strategies.
How much light do row covers allow through to plants?
Most quality row covers allow 80-95% light transmission, ensuring plants receive adequate sunlight for photosynthesis. The Agribon AG-19 allows 90% light transmission, while Frost Protek permits 95%. Easy Gardener’s budget option allows 80% light transmission. This high light penetration prevents stunted growth while maintaining effective pest protection.
Do row covers provide frost protection?
Yes, many row covers offer frost protection ranging from 2-6°F. The lightweight Agribon AG-19 provides 2-4°F protection, while DeWitt’s N-Sulate offers superior 4-6°F frost protection due to its heavier construction. This thermal protection helps extend growing seasons and protects tender plants during unexpected cold snaps.
How long do row covers typically last?
Row cover lifespan varies by material quality and weight. Budget options like Easy Gardener’s fabric last 2-3 seasons, while mid-range covers like Agribon AG-19 last 3-4 seasons. Premium options offer longer durability: DeWitt’s N-Sulate lasts 4-5 years, Planket lasts 5-7 years, and Frost Protek lasts 6-8 seasons with proper care and storage.
When should row covers be removed from plants?
Row covers should be removed during bloom periods for crops requiring pollination, such as tomatoes, peppers, squash, and cucumbers. For leafy greens and root vegetables that don’t require pollination, covers can remain throughout the growing season. Remove covers temporarily for harvesting and plant maintenance activities.
How do you properly install row covers?
Drape row covers loosely over crops to allow room for plant growth. Secure edges with sandbags, ground staples, or weights to prevent pest entry while maintaining proper ventilation. Avoid pulling covers too tight, as this can damage plants and restrict growth. Installation typically takes 10-15 minutes for a standard garden bed.
Are row covers effective against all types of garden pests?
Row covers are highly effective against flying insects, blocking 85-90% of pests like aphids, whiteflies, and cabbage moths. They also deter larger pests like birds and rabbits. However, they’re less effective against crawling pests such as slugs, cutworms, and ground-dwelling insects that may already be present in the soil.
What’s the difference between lightweight and heavy-duty row covers?
Lightweight covers (0.5-1 ounce) offer basic pest protection with maximum light transmission and minimal frost protection. Heavy-duty covers (1.5-2.5 ounces) provide superior thermal protection, durability, and weather resistance but may reduce light transmission slightly. Choose based on your specific climate conditions and protection needs.
