Overwintering Red Banana (Ensete) in the Pacific Northwest

Two Viable Strategies

Red Abyssinian banana (Ensete ventricosum 'Maurelii') is tropical and will not survive freezing temperatures in Redmond, WA (zone 8b).

Option 1: Container Overwintering (Plants Under 4 Feet)

• Move pot indoors before first frost.
• Place in bright window with 6+ hours of direct sun.
• Water sparingly—just enough to keep soil from completely drying.
• Expect slow growth; the goal is survival, not vigor.

Option 2: In-Ground Mulching (Larger Plants)

1. After first frost kills foliage, cut pseudostem to ground level.
2. Apply 12–18 inches of loose mulch (straw, leaves, wood chips) over the corm.
3. In spring, remove mulch gradually as temperatures rise.
4. New growth emerges from the protected rhizome if it didn't freeze.

Key Reminder

Bananas need heat and humidity to thrive. Pacific Northwest summers are often too cool for robust growth; container culture with summer outdoors is often the most practical approach.
