Care at a glance
Light
Full direct sun. Requires generous daily direct sunlight to fuel heavy flower production and keep upright stems sturdy.
Watering
Moderate, consistent watering. Allow the topsoil to dry slightly between waterings; water at ground level to keep dense flower heads dry.
Conditions vary with pot, season and location. Always check the mix and your plant's response.
How to identify it
Stout annual with deeply divided aromatic pinnate leaves and large, globular multi-petaled pompon flower heads in sunny yellow and orange.
Environment and placement
Warm, sunny outdoor conditions. Thrives in summer heat; tender to frost and completes its lifecycle with the autumn cold.

Common question
Why do my potted marigold flower heads rot and turn brown?
The dense pompon flowers trap moisture easily if watered from above; always direct water at the base of the stems into the soil.
