PLACEMENT & CULTIVATION
A new introduction of an heirloom type, once called Double Anemone Cosmos in the early 20th century. This compact variety performs nicely in containers and is tolerant of drought conditions. Pinch out stem tips when plants reach about 1' tall. Deadhead regularly.
Watering Details:
Drought tolerant. Water regularly while establishing, then water only during dry, hot spells.
Soil pH:
Prefers acidic to neutral
Fertilizer:
Cosmos thrive in regular soil and may sprawl in nitrogen rich soils. If desired, an application of organic flower fertilizer can be mixed in around plants.
Diseases & Pests:
No major pests or diseases. Powdery mildew can be discouraged with a regular preventative application of a baking soda based spray.
When to Cut for Bouquets:
Harvest when flowers start to open to 1/2 open; best vase life before the flowers are pollinated.
