Overwintering Geraniums: Yellow, Spindly Growth Is Normal

A geranium kept in a sunny window over winter turning yellow and spindly is exactly what happens when a high-light, warm-climate plant endures short, dim northern days.

Correct Winter Care

• Water: Only when soil is dry 1 inch down. Overwatering causes yellowing.
• Light: Brightest window. Accept legginess.
• No fertilizer.
• Cool temps (55–60°F) help reduce weak growth.

Spring Rehab

1. After frost, move outdoors to shade 7–10 days.
2. Cut back hard to 4–6 inches—this forces bushy basal growth.
3. Repot in fresh mix. Resume feeding.

The unique color variation will return on new growth. Winter ugliness is temporary.
