Marshmallow herb plants prefer moist soils. Some gardeners recommend a fall planting so that the cold temperatures aid in the germination of the Marshmallow herb seeds. If starting the Marshmallow seeds indoors, place the herb seeds in moistened peat moss, and place the peat moss/seed mixture in the refrigerator for 4 to 6 weeks. After that cold treatment, sow the herb seeds in small pots. Once established, it is known to self-seed.
