DeWitt Ultimate Winter Crop Cover - 2.5oz - 3ft x 250ft

DeWitt Ultimate Winter Crop Cover - 2.5oz - 3ft x 250ft

The DeWitt Ultimate Winter Crop Cover is the heaviest-duty fabric in the DeWitt line, designed for extreme cold protection and full-season overwintering of perennials and ornamentals. At 2.5oz, it delivers superior freeze protection even in the harshest winter conditions - holding heat effectively while allowing irrigation and rain to pass through. Even on sunny days, this fabric is engineered to avoid foliage burn, making it safe to leave in place throughout the winter months.

Key Features & Benefits

• 2.5oz extreme protection: The heaviest fabric weight in the DeWitt line for maximum freeze protection in the most demanding winter conditions.
• All-winter durability: Designed specifically for season-long overwintering use on perennials, ornamentals, and other cold-sensitive permanent plantings.
• Heat retention with moisture permeability: Holds warmth beneath the cover while allowing rain and irrigation water to pass through freely - no need to remove the cover for watering.
• No foliage burn on sunny days: Specifically engineered to prevent the heat buildup under the fabric that causes foliage burn in some crop covers, even during warm winter sun periods.
• 3ft x 250ft coverage: Convenient narrow-width roll ideal for individual plant rows, hedgerows, and perennial beds.

Who Should Use This

The DeWitt Ultimate is the right choice for growers and landscapers who need the maximum available protection for perennials, roses, ornamentals, and other valuable plantings that must survive severe winters in place. The all-winter design and no-foliage-burn performance make it the safest option for extended cold-season protection without daily monitoring.

Compatibility

Suitable for draping directly over perennial crowns, shrubs, roses, ornamental trees, and containerized plants. Secure with DeWitt Clip-Its, fabric staples, or sandbag weights. The 3ft narrow width is particularly practical for individual plant wrapping and single-row coverage.

Frequently Asked Questions

How does the Ultimate differ from the DeWitt Supreme?

The Ultimate is heavier at 2.5oz versus Supreme's 1.5oz, and is specifically designed for all-winter season-long use. Supreme is suited for seasonal frost events and shoulder-season protection, while the Ultimate is engineered for the extended, continuous cold of full winter overwintering - particularly for perennials and ornamentals that require all-season protection.

Can I leave this fabric on all winter without checking on plants?

The Ultimate is designed for extended all-winter use, and its no-foliage-burn construction makes it safe to leave in place on typical winter days without daily supervision. However, periodic checks are still recommended, especially after significant snow accumulation or ice loading events that could compress or damage the fabric and plants beneath it.

Does rain and irrigation water pass through this fabric?

Yes. Despite its 2.5oz heavyweight construction, the DeWitt Ultimate is permeable to rain and irrigation water, allowing moisture to reach plant roots without removing the cover. This is a critical feature for all-winter protection of perennial root systems that still require moisture during the dormant season.

Will this fabric cause plants to overheat on warm winter days?

The Ultimate is specifically engineered to avoid the foliage burn that can result from heat accumulation under heavier fabrics on sunny days. This makes it safe to leave in place during the warm spells that commonly occur during winter and early spring without risking thermal damage to the plants beneath.
