Winterizing Angel's Trumpet and Confederate Rose in Zone 7/8

Protecting Brugmansia and Hibiscus mutabilis from Freeze

Greenville, SC (Zone 7b/8a) getting cold: two options for angel's trumpet (Brugmansia) and Confederate rose (Hibiscus mutabilis).

Option 1: In-Ground with Heavy Protection

• Prune back to 12–18"
• Mulch 12–18" over crown (straw, leaves, pine straw)
• Cover with frost cloth/tarp during hard freezes
• Risk: ground freeze kills roots

Option 2: Containerize and Move (Recommended)

• Dig, pot in large container (whiskey barrel size)
• Move to garage/shed (40°F+)
• Water sparingly—dormant plants need little
• Return outdoors after last frost

Key Principle

Prevent root ball freezing. Top growth sacrifice is fine; roots must survive. Container method guarantees this.
