did you know?

Cosmos is native to Mexico, but the name is derived from the Greek word for "beautiful" or "ornament."

general maintenance:

Deadhead, removing each stem as well as its spent flowers, to increase bud production and ensure continued flowering.

pests/diseases:

Aphids and powdery mildew may occur.

controls:

Regularly hose off aphids with a directed stream of water, or apply insecticidal soap, following label directions. To discourage powdery mildew, space plants for adequate air circulation, and avoid wetting leaves when watering. Pick off diseased leaves where practical, and remove and destroy severely infected plants.

how to sow/plant:

Plant in spring. Direct sow when danger of frost has passed, or start indoors 4?6 weeks before last frost. Sow 1/4 inch deep, and thin to (or transplant) 12?18 inches apart. Cosmos transplants easily. Water after planting, and mulch to conserve water.

water and fertilize:

Maintain uniform moisture all season. Fertilize biweekly with a diluted solution of soluble fertilizer. Do not overfertilize, which leads to excessive leaf growth at the expense of increased flowering.

garden hint:

To promote flower production, plant cosmos in soil that is not too fertile because rich soil promotes foliage at the expense of flowers.
