How to grow
If planning to grow Cosmea and other Cosmos members outdoors then the seeds should be sown out after the last frost of spring at a depth of 3mm. 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.
