Dandelion - Key Growing Information
DAYS TO GERMINATION: 7-21 days. Germinates better in cool soils.
SOWING: Direct seed (recommended): Direct seed anytime after the last spring frost or plant 6 weeks before the first frost in the fall. Sow shallowly, as seed requires some light to germinate, one seed per inch. Thin plants to 4-6" apart in rows 12-18" apart.
Transplant: Can be sown in flats and transplanted outdoors at anytime. If you are growing for roots, it is best not to transplant, as transplanting disturbs the root shape.
DISEASE: Dandelion leaves are sometimes prone to mildew, which is exacerbated by humidity and any kind of plant stress. To reduce the likelihood of mildew, keep the soil moist, minimize overhead irrigation, and space plants at recommended distance to allow for good air circulation between the plants. Mildew on the leaves reduces root growth in proportion to the severity of the mildew.
LIGHT PREFERENCE: Sun.
SOIL REQUIREMENTS: Adaptable to most soil types, but produces larger roots in a rich, deep, moist soil.
PLANT HEIGHT: 8-18".
PLANT SPACING: 4-6".
HARDINESS ZONES: Zones 3-10.
HARVEST: Leaves are harvested when they are still tender and sweet, before flowering, during the first year.
SCIENTIFIC NAME: Taraxacum officinale
