How To Grow Dandelions

Is the dandelion ​(Taraxacum officinale​) a weed? While many gardeners view the dandelion in this light, this hardy and resilient plant is carving out a new role for itself in the garden as a fast-growing, low-maintenance crop plant that also offers an early source of pollen for pollinators and forage for livestock — and don't forget the chipper yellow flowers, beloved by children everywhere. Dandelions are perennials in U.S. Department of Agriculture plant hardiness zones 3 through 9 but are also found in the wild through zone 10.

Dandelions are perennial plants in the sunflower family (Asteraceae) but are considered weeds by many homeowners. As tough survivor plants, dandelions can be seen in almost any area with soil, and they even spring up beside the freeway and between cracks in the sidewalk. Gardeners either love or hate dandelions. Some are charmed by their bright-yellow flowers that turn to puff balls of seeds, while others dread their regular appearance on the lawn, where they are extremely difficult to eradicate. Anyone planting dandelions can grow them in a sunny location in the vegetable garden, where they are more likely to develop large, luscious leaves.

Dandelions also have practical purposes in the garden.

• ​Every part of the dandelion plant is edible.​ The young leaves gathered in spring can be added to salads, added to soups or stir-fried and eaten as dandelion greens. The yellow flowers are also edible and quite mild. The individual petals can be pulled out and sprinkled on top of a salad or soup. The flowers can be fried or used to make jam. They can also be used to make dandelion wine, and the deep taproot is roasted and eaten like any root vegetable or used to make tea.
• ​Dandelions can be used as medicinal plants.​ The leaves are slightly bitter and are believed to improve digestion. They also are eaten for their nutritional value and are said to be
  high in calcium, phosphorous, carotenes, and potassium. Leaves also have diuretic properties and are used to treat high blood pressure and edema among other issues. Sap from the dandelion stem is used as a treatment for warts. The roots are used in treatments for liver issues.

Dandelions grow best in U.S. Department of Agriculture plant hardiness zones 3 through 9. If you live in zone 10 or 11 and want to grow dandelions in your garden, put them in a site that gets shade all afternoon.

Dandelions can be planted in spring in all regions, and this is the best time to plant them. They can develop the deep taproots that make them resilient after a summer of strong growth. As many homeowners with lawns have come to understand, dandelion roots are almost indestructible. Even if a large section of root is removed, the plant will regenerate and thrive.

In temperate climates, dandelions can also be planted in autumn or even in winter. Dandelions blossom virtually all year long in mild climates, and seeds can also germinate all year long.

It's hard to think of dandelions as picky about soil when you see them sprouting happily from a crack in the sidewalk. The truth is that dandelions will grow on almost any type of soil. However, the type of soil on which they grow does impact taste. Anyone growing dandelions who intends to eat the leaves will want to prepare the soil well for these perennials.

Soil for Dandelions

To get the best-tasting dandelions, sow your seeds in well-draining loam that has been enriched with composted manure or organic compost. Alkaline soil is preferable. The soil should be broken up and tilled to at least 10 inches.

Yes, dandelions grow in any exposure, from bright, direct sun to deep shade, but again, the taste of the plant is different in different growing conditions. Ideally, dandelions will grow with some sun and some shade. In cooler areas, full-sun areas may do nicely. The hotter the summer in a region, the more afternoon shade the dandelions will require.

Water is particularly important to dandelions when they are germinating or are young seedlings. During these periods, you'll want to keep the soil moist. After the plants have established, a once-a-week irrigation plan should be fine.

Since all parts of the dandelion plant are edible, harvest can look different depending on what you want to eat. Most people eat dandelion "greens," which means the plant's leaves. There is no single point of harvest for these. Leaves are most tender just after they appear in spring, but you can use your garden scissors to snip off a few at a time during the entire growing season. If you harvest leaves throughout the season, you may find them increasingly bitter. To prevent this, blanch the leaves by covering the plants from sunlight for two weeks before harvest.

The dandelion roots are best harvested after the plants are two years old. Dig them up in the fall after the first frost since they are highest in inulin at that time, resulting in a sweeter taste and more nutrients. Alternatively, harvest them in late spring before they flower.

Obviously, once you harvest the roots of a dandelion plant, it will not grow back the following year unless you replant. If you are growing dandelions for both the roots and leaves, you might divide your site into four sections, taking the roots from one section in fall and sowing seeds in that section the following spring. The following fall, take the roots from another section.

Homeowners armed with toxic chemicals and weed removers have not been able to conquer dandelions in lawns. That means it is no surprise that dandelions have very few garden pests that threaten their health or existence. With or without water, sun, shade or cultivated soil, dandelions keep popping out of the ground. However, there are a few problems for which to look out:

• ​Excess sun​: Too much sun won't kill a dandelion, but it will make the leaves tough and bitter. Protect your plants by siting them where they get shade from the afternoon sun.
• ​Horses, cows, goats and sheep​: Dandelions growing in fields provide supplemental forage for livestock. Your best defense against these herbivores is to keep them out of your garden area since they are likely to enjoy almost any crop you have growing there in addition to the dandelions.
• ​Common cockchafer​: This insect pest spends the early part of its life cycle — the first three years — as a grub. During this stage, it lives underground and eats the roots of different plants. This voracious pest's favorite meal is dandelion roots. However, you don't have to worry about the cockchafer since the dandelion once again shows what resiliency means.
  Dandelion roots produce a bitter substance called latex that fends off the pests. The latex contains one substance that inhibits the growth of the cockchafer grub.
• ​Ruby tiger moth larvae:​ These caterpillars love to feed on dandelion leaves. They are large enough that you'll be able to spot them and pick them off your plants by hand.

Powdery mildew is a fungal disease that attacks dandelions just like other garden plants. It shows up as a white powder on the foliage. Deal with this problem by spraying the plants with neem oil. Better yet, eliminate the problem by not getting irrigation water on the dandelion leaves.
