Overwintering Begonias Indoors: Dig, Pot, and Window Care

A gardener near Washington, DC wanted to save store-bought wax begonias (pink and white, glossy leaves) and their self-sown seedlings over winter.

Indoor Care

• Begonias die outdoors in frost but overwinter easily inside.
• Dig up before frost, pot in quality indoor mix (Jungle Growth, Redi-Mix, etc.).
• Place in bright east (morning sun) window.
• Water by weight: water thoroughly, let sit 5–10 min, drain saucer. Pot should feel heavy. Water again when significantly lighter (1–2×/week).
• Expect ragged look until spring; they'll rebound when returned outdoors in May.

Seedlings can be potted separately. Both will survive and bloom next season.
