Growing Requirements for Dandelions

Sun and Moisture

• Dandelions aren’t particularly picky about how much sunlight and what kind of soil they are grown in. They do prefer full sun, at least six hours per day, and dry, well-draining soil. However, once established, they will survive in shade, dry soil, or soil that tends to hold onto moisture. In short, dandelions are tenacious plants requiring little care in order to thrive.

Germination

• Dandelion seeds must be planted or found close to the surface of the soil -- no more than 1/2 inch deep, according to the Small Farm Resource. Light increases germination, but isn’t absolutely necessary. According to the University of California, UC Davis, Agriculture and Natural Resources website, dandelion seeds germinate when soil is moist and at least 50 degrees Fahrenheit. Germination is faster when the soil is 77 F. Germination of dandelion seeds occurs throughout the growing season, although seedlings grow slower in cold weather. In regions with snow, dandelions might die back in the winter, but the taproot will remain strong.

Taproots and Crowns

• The taproot of dandelions is legendary. Growing up to several feet long, it is the taproot that makes dandelions so difficult to remove from the garden or lawn. From the taproot, a crown grows that enables the plant to create new growth even when the green parts of the dandelion, which is everything above the soil, are completely removed.

Pollination

• Dandelions do not require pollination to grow and thrive. Sometimes bees and other animals pollinate dandelions, but according to the University of California, UC Davis website, dandelions normally reproduce asexually.

Timing

• Although many gardeners find dandelions the bane of their landscaping, an increasing number of people are rediscovering the benefits of dandelions for eating and herbal medicine. Typically, dandelions are planted in the middle of summer in order to obtain a good fall crop. Overwintered dandelions taste best in the spring, before new buds form.
