Overwintering Bougainvillea, New Guinea Impatiens & Begonia in Minnesota

All Three Must Come Indoors in Zone 4

Bougainvillea

• Prune only to manage size.
• Bright east/south window.
• Water sparingly; no fertilizer.
• Expect massive leaf drop—normal.
• Spring: 10 days shade, then sun; resume water/feed.

New Guinea Impatiens & Elephant Ear Begonia

• Same: bright window, weekly water, no feed until spring.
• Both tolerate indoor conditions well.
• Move out after nights consistently >50°F.

Group them in your sunniest window. They'll hold until spring.
