Plant Protection Products Buying Guide
Protecting plants from frost, pests, and hungry wildlife does not always require chemicals. A range of physical barriers, from lightweight cloth to simple plastic collars, can do a lot of the work. Here is how the main types differ and when each makes sense.
Row Covers and Frost Cloth
Row covers are lightweight fabric sheets laid directly over plants or draped across hoops to form a low tunnel. Lighter-weight versions are mainly used to keep insects off young plants while still letting in light, water, and air. Heavier frost cloth is designed to trap a few extra degrees of warmth around plants, which can be enough to protect tender seedlings or extend the growing season on either end of the year. Check the weight or fabric rating, since lighter covers offer less frost protection but let in more light, and heavier ones do the opposite.
Netting for Birds and Insects
Netting is generally used to keep birds off ripening fruit and berries, or to exclude larger insects from vegetable beds. Mesh size matters: a fine mesh stops small insects but can also block pollinators if left on during flowering, so it is worth removing or opening netting when plants need to be pollinated. Netting draped loosely over a support structure is usually easier to work with than netting laid directly on plants, since it avoids crushing foliage and gives pests less of a foothold to reach through the mesh.
Cloches
Cloches are individual covers, often dome or tent-shaped, placed over a single plant or a small cluster of seedlings. They are especially useful early in the season for protecting young transplants from a late frost or from cold wind while they establish. Because they cover a small area, they trap more warmth than a full row cover, but need to be removed or vented on warm days to avoid overheating the plant underneath.
Plant Collars
Plant collars are small rings placed around the base of a seedling’s stem, mainly to stop cutworms and similar pests from chewing through the stem at soil level. They are a simple, low-cost way to protect young transplants during their most vulnerable weeks and can usually be removed once the stem has thickened and the plant is established.
Matching Protection to the Season
- Early spring: Cloches and plant collars protect young transplants from cold snaps and cutworms while they get established.
- Growing season: Lightweight insect netting or row covers keep pests off without blocking light, though they should be removed during flowering if pollination is needed.
- Fruit ripening: Bird netting protects the harvest as fruit and berries ripen.
- Fall and early winter: Heavier frost cloth extends the season for cold-tolerant crops and protects against the first light frosts.

Final Thoughts
Most gardens end up using a combination of these products rather than just one. Matching the right cover to the specific threat, whether that is frost, insects, birds, or cutworms, works better than relying on a single all-purpose barrier.
