Daisy Tree (Argyranthemum) Winter Care Indoors: Dormancy, Repotting & Spring Revival

Tropical Daisy Tree Indoors: Semi-Dormancy Is Normal

In the Midwest, daisy trees (Argyranthemum frutescens) brought inside for winter drop leaves, stop blooming, and look sickly. This is a response to low light and dry air—not death.

Winter Care (Now)

• Max sun: South/east window.
• Water sparingly: Only when top inch dry.
• No fertilizer.
• Light pruning: Remove only dead twigs; don't hard-prune.

Repotting: Do It Now (During Dormancy)

Best time: while semi-dormant (late winter).

1. Choose pot 2″ larger.
2. Loosen root ball; trim circling roots.
3. Use rich, well-drained potting mix.
4. Plant slightly deeper; water; place in sun.

Spring Transition (After Last Frost, Nights >50°F)

1. 10 days in full shade outdoors.
2. Then full sun.
3. Resume regular water & balanced fertilizer (12-12-12).

The plant will rebound vigorously.
