Wait until spring when the dandelions begin sprouting so you can properly identify them. Select dandelions from pesticide- and herbicide-free fields or yards and away from roads.
Snip off flowers early in the season when they are still young. Leave 1 to 2 inches of the lower stem on the plant because this part can be tough.
Cut the greens off at the soil level or dig the entire plant out of the ground, using a hand spade. Cut off the bulb. Wash the greens before eating or cooking.
