Overwintering Catalpa Seedlings in Northern South Dakota

Protecting Young Catalpa Trees in Zone 4

Catalpa seedlings in pots go dormant naturally. To overwinter:

• Move pots to an unheated garage or shed.
• Shield from direct north wind.
• Water occasionally—don’t let root balls dry completely.
• No light needed during dormancy.

In spring, bring out after last frost; they’ll leaf out quickly. Catalpa is tough once established.
