6. Fertilize the dandelions' soil when the plants are 4 to 6 inches tall then twice each month for the rest of the growing season. Combine 2 tablespoons of the concentrated fertilizer mixture with 1 gallon of water, and use the solution to water the dandelion's soil until it is damp all the way through. Place dandelion seeds 1 1/2 inches apart on the pot's soil. Sprinkle a little potting soil over each seed until all the seeds are barely covered, about 1/8 inch deep in the soil. Spray the soil with water, dampening the seeds. Place the pot in a bright spot indoors, and keep its soil moist. PARTS USED: Every part of the dandelion is edible, including the roots, leaves, crowns and flower buds. SOIL REQUIREMENTS: This plant is one of the hardiest around. It can grow most everywhere, regardless of soil conditions, but does best in rich soil with sufficient moisture. Dandelion. LATIN NAME: Taraxacum officinale. HISTORY: Dandelions are believed to be some of the oldest plants on the planet. Historians and biologists have found the plants appearance in fossils dating back thirty million years ago in Eurasia. One estimate is that more than 240,000,000 seeds/acre could be produced annually by a dense stand of dandelions. Flowering peaks in early summer with a second flush of flowers from mid-September to early October. Some plants may flower any time during the growing season. Two patterns of flowering are found. Flower heads open for 2 to 3 days in early spring and mid to late fall and for less than 2 days in the summer. The heads remain closed for 10 days in the early spring and fall, 6 to 7 days in the summer and 20 days in late fall before opening a second time to release seed. Although dandelions grow through the fall, the best time to harvest dandelions is in the spring. Dandelions get bitter the older they get, so if you can pluck them young you’re going to experience a sweeter flavor. However, I ate dandelion leaves all last spring and summer, and enjoyed them all.  In rich soil, each plant spreads 18 - 24 inches across. Dandelion requires a long growing season and develops best at low temperatures. Sow seeds 1/4 to 1/2 inch deep in May to early summer and thin seedlings to 8 to 12 inches apart in the row. The plants form a rosette of leaves and overwinter in the garden. They will grow in any well-drained garden soil The leaves and flower stalks contain a white sap. The flowers give rise to a puff ball of brown seeds connected to downy parachutes. Seedlings emerge from late spring to early fall, with most emerging in early summer. Dandelion will grow in almost any soil type and is most commonly found in sunny areas. It reproduces by seed and from new plants that develop from pieces of broken taproots.  Planting.

Most people regard the dandelion (Taraxacum officinale) as an invasive weed that takes over lawns and flower beds every spring. While in many cases this is true, dandelions can also be planted as a food source. 2. Sow your dandelion seeds 1/4 to 1/2 inch deep in your seedbed in mid-to late spring, spacing the seeds 2 to 3 inches apart. Dandelion seeds require a great deal of light to germinate, so do not cover the seeds with soil. Water your dandelion seeds lightly, keeping the top inch of soil moist but not wet. Dandelions grow quickly when well-watered, so it is best to control the amount of water your dandelions get so they do not grow out of control
