DeWitt’s SUPREME line delivers the heaviest-duty plant protection fabric on the market at 1.5 oz weight. The fabric keeps temperatures underneath 6 to 8 degrees Fahrenheit warmer than outside air, compared to lighter fabrics that typically provide only 2-4 degrees of protection. Lighter 0.5 oz or 1.0 oz alternatives can’t match this performance level.
For Montana contractors dealing with unpredictable spring and fall freezes, that 6-8°F buffer makes the difference between dead plants and a successful installation. The heavy fabric also stands up to Montana wind conditions better than flimsy alternatives.
SUPREME650 Specifications
The SUPREME650 covers serious ground for commercial landscaping projects.
| Specification | Value |

| Material | Plastic / Non-woven Fabric |
| Fabric Weight | 1.5 oz |

The fabric is folded to 3 feet and rolled into a core for easier storage and deployment. This matters when crews are covering hundreds of feet of plantings before a freeze warning.
Applications and Performance
The SUPREME650 is designed for protecting flowering annuals, bedding plants, and vegetables from severe cold and freezing. It handles both large residential and commercial landscaping and gardening applications.
The real advantage shows up in extending the growing season in early spring or late fall. Montana’s short season means every extra week counts. The fabric allows moisture and light to reach plants while providing protection, so it can stay on longer than plastic sheeting without cooking the plants underneath.
Reusable year after year — fold it up, store it dry, and it’ll be ready next season. Installation is easy; the fabric can be secured with landscape staples, pins, or stakes.
The SUPREME line fills a specific need — serious frost protection for commercial projects where plant replacement matters. Not every job needs 1.5 oz fabric. But when temperatures drop unexpectedly and thousands of plantings hang in the balance, that extra protection margin justifies the investment.
Frequently Asked Questions
Q: How does 6-8°F protection compare to standard frost blankets?
A: The 1.5 oz SUPREME fabric provides 6-8 degrees of frost protection, whereas lighter fabrics typically provide 2-4 degrees. That extra 4 degrees often means the difference between minor cold damage and total plant loss during Montana’s surprise freezes.

A: The package includes one 6’ x 50’ sheet of SUPREME650 fabric. Recommended accessories include landscape staples, securing pins, and anchoring stakes for installation.

A: Yes, it’s designed for crop protection for winterization. The heavy fabric weight and reusable year after year design make it practical for protecting perennials and shrubs through winter.
