How to Grow Cosmos

If planning to grow Cosmea, Mexican Aster and other Cosmos members outdoors then the seeds should be sown out after the last frost of spring at a depth of 3 mm. They prefer to grow in a sunny area of the garden that has poor soil of PH 5 to 7. if you are planning to fist grow Cosmos indoors as seedlings then they should be started off about 5 weeks before they are due to be put out in spring (following the last frost). They take about half to one and a half weeks to germinate at a temperature of about 21 to 24 degrees centigrade.

Caring for Cosmos in the Garden

Once growing it is best to pinch out the growing tips of the plant when it reaches an height of about 40 cm to encourage bushiness and more blooms. Cosmos requires watering during prolonged dry spells.
