You might think frost cloth and row covers are different, but frost cloth is actually just a type of row cover made for cold protection. Both are typically polypropylene and come in weights that balance warmth, light, and durability. Medium weights, like Agribon AG-30, offer solid frost defense—raising temps by 4–8°F—while also blocking pests. Lightweight versions suit insect control and warm seasons, while heavier ones insulate against harsh freezes. Your choice depends on climate, crops, and season, with proper setup enhancing effectiveness. There’s more to using them well than just draping them over plants.
TLDR
- Frost cloth is a type of row cover specifically used for insulation against cold, not a separate product.
- Row cover is the broad category, including fabrics for frost protection, pest control, and growth enhancement.
- Both are typically made of polypropylene, with weight determining warmth and light transmission.
- Heavier row covers (like AG-50 or AG-70) offer frost protection down to 24°F, adding 4–8°F of warmth.
- Frost cloth and row covers can both block pests, with fabric weight balancing light, airflow, and insulation needs.
What’s the Difference Between Frost Cloth and Row Covers?
What exactly sets frost cloth apart from row covers—aren’t they the same thing? You’re right to wonder, since frost cloth isn’t a separate product but a term highlighting insulation use.
Row cover is the broader category, with frost cloth emphasizing cold protection. Both are made of polypropylene, come in weights affecting light and warmth, and serve multiple garden roles. Can raise temperatures underneath by 2°F–10°F. Planted in full sun, many drought-tolerant tropicals like lantana and bougainvillea also tolerate light row cover use when protecting blooms.
Which One Offers Better Frost Protection?
You’ve seen how frost cloth and row covers overlap in material and purpose, but when cold weather hits, the real test is which one keeps your plants warmer.
Heavier fabrics like Agribon AG-50 or AG-70 protect down to 24°F, offering 4–8°F of insulation. For most winter growing, medium-weight AG-30 balances protection, light, and durability, making it your best bet for reliable frost defense.
What Are the Different Types of Row Covers For?
While your garden’s needs may vary with the season, choosing the right row cover starts with understanding how each type functions in practice.
Floating covers suit quick growth and pest control, while supported ones prevent damage and enhance airflow.
Lightweight fabrics block insects, medium weights balance warmth and light for frost protection, and heavy options insulate crops in harsh cold.
Coconut coir chips offer exceptional moisture retention and aeration for containers and could complement row-covered beds when managing soil water balance, especially with coconut coir substrates.
Do Both Covers Block Pests and Shade Plants?
Both frost cloth and row covers serve as effective barriers against common garden pests, using physical exclusion to keep harmful insects at bay without relying on chemicals.
You can choose finer fabrics to block tiny pests like aphids or coarser weaves for larger insects.
Both also provide shade, with lighter weights offering higher sunlight transmission—ideal for warm seasons—while heavier options reduce light and heat, balancing protection and plant needs.
Many gardeners also show appreciation to their regular maintenance crew with seasonal gratuities like a holiday bonus to acknowledge consistent service.
How Do I Pick the Right Cover for My Garden?
Start by evaluating your local climate and seasonal needs to choose the right cover for your garden.
In cold zones, pick heavyweight fabric for 4–8°F protection, while mild areas thrive with lightweight covers offering higher light transmission.
Match material to your crops—use breathable fabric for humidity-loving plants and opt for hoops to enhance insulation.
Secure edges well, and double layers when extreme frost hits.
Sedums like Gold Moss are low-maintenance, drought-tolerant groundcovers that prefer well-drained soil and full sun, so consider coverage that won’t trap excess moisture around the plants.
Final Note
You now know frost cloth offers superior cold protection, while row covers vary by weight and serve multiple purposes, from insect barriers to light frost defense. Both can block pests and provide shade, but always match the cover’s specs to your needs. Choose heavier fabrics for freezing temps and lighter weaves for insect control. Always secure edges to maximize effectiveness. Making the right choice protects your plants and enhances garden success.
