Alcea Growing Information

Alcea Rosea
HollyHock

Planting:

Set out plants 2 to 2 and 1/2 feet apart in either spring or fall. A moist, well-drained soil and full sun are preferred – if necessary add compost and coarse sand to lighten heavy clay soil. Set crowns slightly below the surface of the soil.


Maintenance:

Keep well-watered during periods of drought. Hollyhocks may require staking to protect them against strong winds. Hollyhocks may tend to be rather short lived and require replacement every few years.


Zones:

Zones 3 to 9
