DeWitt Supreme Winter Plant Protection Fabric - 1.5oz - 36ft x 500ft - White

DeWitt Supreme Winter Plant Protection Fabric - 1.5oz - 36ft x 500ft

DeWitt Supreme Plant Protection Fabric is designed to shield flowering annuals, bedding plants, and vegetable crops from frost and freezing temperatures. The 1.5oz white fabric provides +6°F to +8°F of frost protection, creating a warmer microclimate beneath the cover that extends the growing season well into cooler weather. The 36ft x 500ft roll is folded to a manageable 12ft width for easy handling and deployment across large growing areas.

Key Features & Benefits

• +6°F to +8°F frost protection: Significant thermal protection for flowering annuals, bedding plants, and vegetable crops during hard frost events.
• 1.5oz heavyweight construction: Durable fabric with substantial thermal mass for reliable cold-weather protection in demanding conditions.
• 50% white opacity: Diffuses light while retaining heat - the white color reflects excess sunlight to prevent overheating on warmer days while the opacity retains heat at night.
• 36ft x 500ft coverage: Large roll for efficient coverage of commercial-scale beds, rows, and nursery benches.
• Folded to 12ft: Pre-folded for practical handling - easy to carry, deploy, and store without managing the full 36ft width.
• Season extension: Creates a warmer microclimate that extends productive growing periods into cooler shoulder seasons.

Who Should Use This

DeWitt Supreme is ideal for wholesale nurseries, bedding plant growers, and commercial vegetable producers who need reliable heavy-frost protection for large areas of tender crops. The 36ft x 500ft roll provides acre-scale coverage, and the 1.5oz fabric weight delivers the thermal protection needed for cold hardiness zones where late frosts regularly threaten spring plantings.

Compatibility

Suitable for use over field rows, raised beds, greenhouse benches, and outdoor containerized nursery stock. Can be secured with DeWitt Clip-Its, fabric staples, sandbag weights, or soil burial. The 50% white opacity helps prevent heat accumulation under the cover during warmer daytime periods.

Frequently Asked Questions

How does DeWitt Supreme compare to lightweight row covers?

DeWitt Supreme is a 1.5oz heavyweight fabric providing +6-8°F frost protection, compared to lightweight fabrics (0.5-0.6oz) that typically provide only +2-4°F. Supreme is designed for serious frost and freeze events where lighter covers are insufficient. The trade-off is lower light transmission (50%) compared to lightweight covers (70-95%).

Why is the fabric folded to 12ft?

The 36ft roll is folded to a 12ft working width for practical handling in the field. When deployed, simply unfold the fabric to its full 36ft width to cover wide rows, benches, or multiple beds in a single pass. The pre-folded format makes it much easier to carry and manage compared to a full-width 36ft roll.

Can DeWitt Supreme be left on crops during the day?

The 50% white opacity limits light availability and can cause heat accumulation under the cover on warm sunny days. For actively growing crops, it is generally recommended to remove or vent the fabric during warm daytime periods and re-apply before nightfall when frost is expected.

Is this fabric reusable?

Yes. DeWitt Supreme is designed for seasonal use and reuse with proper care. After use, allow the fabric to dry completely, remove soil and debris, and store rolled or folded in a dry location away from UV exposure and rodents between uses.
