If planning to grow annual Chrysanthemums outside from seeds, then they should be sown at a depth of 3mm into a sunny area of the garden that has good drainage before the last frost of spring.
If you plan to grow Chrysanthemum plants indoors first then the process should be started about 2 months before you plan to transplant the seedlings outdoors (generally after the last frost of spring).
Corn Marigold / Annual Chrysanthemum takes about one and a half weeks to germinate at around 18 degrees Celcius.
It is easy to carry out chrysanthemum care. Once growing pinching the annual Chrysanthemum seedlings will help to create bushy plants. Once flowers have finished they should be removed. It may be necessary to stake the taller varieties of annual Chrysanthemum.
Chrysanthemum paludosum (Mini Margueritte, Creeping Daisy , Snow Daisy,)
These very tender perennials are grown as annuals in the garden. They reach an height of 12 to 18 inches (30 to 45cm) and have White petals with a yellow center. They are able to grow successfully in zones 9 to 11 in the USA. Sow them about 10 inches (25cm) apart in a sunny area of the garden after the last frost of spring; or start indoors and transplant later. Depending upon when started they will bloom from Late Spring (started Indoors) or Summer and continue through to the middle of autumn. They are able to tolerate many soil types. For best results pinch the plants to encourage bushiness, and deadhead to encourage further blooming.
Chrysanthemum segetum (Glebionis segetum), Corn Chrysanthemum, Corn Marigold
These annual plants reach an height of 12 to 24 inches (30 to 60cm) and carry yellow flowers that come into bloom from the middle of summer and remain through to the start of autumn. They are able to grow in partially shaded areas, but have a preference for sunny areas. Seeds can be sown either in the autumn or spring, and should be spaced about 12 to 15 inches (30 to 40 cm) apart. They have been recorded as growing successfully in the USA in zones 4 through to 11.
