Row covers are an easy, chemical-free way to shield your plants from pests. They block insects, reduce pesticide use, and promote healthier gardens. Here's what you need to know:
- Types of Row Covers: Floating, supported, heavyweight, and insect barrier covers offer different levels of protection for various crops.
- Choosing Row Covers: Consider light transmission, weight, durability, and size to match your garden's needs.
- Materials: Options like spunbonded polyester or UV-stabilized polypropylene vary in lifespan and protection levels.
- Installation: Use stakes, hoops, and pins to secure covers properly.
- Maintenance: Inspect regularly, repair damage, and store covers correctly to extend their life.
- Advanced Tips: Combine row covers with other methods like companion planting, sticky traps, or neem oil for better pest control.
Quick Comparison of Row Covers:
| Type | Material | Best For | Protection Level |
|---|---|---|---|
| Floating | Lightweight polyester | Leafy greens, seedlings | Light |
| Supported | Heavy-duty polypropylene | Tomatoes, peppers | Medium |
| Heavyweight | Dense polyethylene | Winter crops | Heavy |
| Insect Barrier | Ultra-fine mesh | Small flying insects | Specialized |
Protect your plants year-round by using the right covers and care techniques. Row covers are an effective, eco-friendly solution for managing pests!
Choosing Row Covers
Selection Criteria
When picking row covers, keep these key factors in mind:
- Light Transmission: Most vegetables thrive with covers that allow 85–90% light through. Seedlings can manage with 70–75%.
- Weight and Durability: Choose based on the season:
- Lightweight (0.5–0.6 oz): Best for summer.
- Medium (0.9–1.25 oz): Ideal for spring and fall.
- Heavy (1.5–2.0 oz): Provides winter protection.
- Size Requirements: Add an extra foot on each side (2 feet in total width) and 9 inches at each end (18 inches total length) to ensure complete coverage and secure anchoring.
Once you've considered these, evaluate the materials to find the right match.
Row Cover Materials
Each material offers unique benefits for protection and longevity. Here's a quick comparison:
| Material Type | Protection Level | Lifespan | Best Uses |
|---|---|---|---|
| Spunbonded Polyester | Medium | 2–3 seasons | Shields crops from flying insects |
| Agricultural Fabric | High | 3–4 seasons | Blocks beetles, aphids, and leaf miners |
| Fine Mesh Netting | Light | 4–5 seasons | Keeps out very small flying insects |
| UV-Stabilized Polypropylene | Heavy | 5+ seasons | Handles pests and tough weather conditions |
Additional Tips:
- Spunbonded fabrics improve airflow.
- Woven options resist tearing.
- UV-stabilized materials hold up better in sunlight.
- In warm climates, fine mesh is great for small pests, while coarser mesh works well for larger insects.

Maintenance Guide
Once your row covers are set up, keeping them in good condition is key to maintaining their protective function throughout the season. Regular care not only ensures effective pest control but also extends the life of your covers.
Regular Inspections
Check your row covers twice a week during the growing season. Pay attention to:
- Physical damage: Look for any tears, holes, or weak spots.
- Anchor points: Make sure stakes and pins are still secure, especially after windy conditions.
- Plant health: Watch for changes in leaf color or growth patterns.
- Pest activity: Look for any signs of insects that may have gotten underneath.
For best results, gently lift the covers in the morning to reduce heat buildup, particularly around the edges.
Care and Storage
Taking care of your row covers during use and storing them properly in the off-season will help them last longer.
During Use:
- Use a soft brush to remove debris regularly.
- Fix small tears right away with repair tape made for garden fabrics.
- Keep the covers tight to avoid water pooling on the surface.
- Remove the covers during heavy rain or hail to prevent damage.
End-of-Season Storage:
- Wash the covers with mild soap and water, then let them dry completely in a shaded area.
- Fold them neatly, avoiding sharp creases that could weaken the material.
- Store the covers in a sealed container in a cool, dry spot.
If your covers show heavy wear or have multiple patches, it might be time to replace them before the next growing season. Having extra materials ready can also help with quick repairs during critical times.
Advanced Tips
Seasonal Planning
Use row covers strategically throughout the year to protect your plants. In early spring, install them when the soil temperature hits 50°F (10°C) to shield young seedlings. Adjust the covers as the seasons change:
- Spring: Install from mid-March to early April across most U.S. regions.
- Summer: Swap to lighter covers when temperatures exceed 85°F (29°C).
- Fall: Reapply covers in September to guard against pests.
- Winter: Remove covers before the first frost unless they’re essential for cold protection.
Stay alert to local weather patterns and pest activity to refine your timing. For best results, keep the covers on for at least four weeks after planting.
Combined Protection Methods
For even better outcomes, pair row covers with other defense strategies.
Physical barriers can add an extra layer of protection:
- Copper tape around garden beds
- Sticky traps to catch flying pests
- Gravel borders to block crawling insects
Natural deterrents work well alongside row covers:
- Plant aromatic herbs like basil, rosemary, or thyme along the edges.
- Use companion planting to create a pest-resistant environment.
- Apply organic neem oil treatments as needed.
