Because of the long growing season required for mum seeds, it is best to start them indoors six to eight weeks before the date of the last frost or sow the seed in spring in a well prepared bed.
Start your mum seeds indoors at least 6 weeks before the last frost. Use potting soil or mix 4 parts of peat moss, 2 parts of perlite and 2 parts of vermiculite.
