Common Questions

Tree Mallow questions

What zones can Tree Mallow grow in?

Tree Mallow is hardy in USDA Zones 9–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Tree Mallow deer resistant?

Yes — Tree Mallow is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.

When does Tree Mallow bloom?

Tree Mallow typically blooms in mid-summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Tree Mallow need full sun?

Tree Mallow does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Tree Mallow drought tolerant?

Yes — once established (usually after the first full season), Tree Mallow handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
