Spring 2020 Promo: $20 off a Smart Lawn Plan + FREE soil test
How to identify and manage dandelions, one of the most familiar and
invasive lawn weeds. It's hard to miss the bright yellow flowers in the
green, green grass. Photos are included to help with weed id.
They are simple perennials with a long taproot that allows them to survive the winter and regrow in the spring. A tiny piece of the taproot is capable of forming a new plant.
Every plant is able to produce hundreds of seeds - spreading them around your yard and carried on winds for miles. These seeds will spread and germinate throughout the growing season.
You can eat them - the whole plant is edible. The greens are used in salads and are high in vitamin A and C. The flowers are used to make wine and the roots ground and used as a coffee substitute - I'll stick to my regular brew :)
Little girls love picking the bright yellow flowers, presenting a bouquet of flowers to their mothers. Kids enjoy blowing the puff-balls, watching the seeds float away...into your neighbor's yard.

Dandelions thrive in full sun and invade thin, stressed lawns - the best way to prevent an invasion is to keep your lawn healthy and dense. A healthy, thick lawn will out-compete most weeds.
The best time to attack them is right after they bloom in the spring this is when food stored in roots is low and its harder to re-sprout. Pull or spray them before they form seeds that spread around your yard.
Hand Weeding: Pull or dig after a rain or irrigation - when the soil is moist. Weeding tools help extract the long taproot.
Spot spray with a broadleaf herbicide in late spring or fall.

Simple perennial from a basal rosette. Ooze a milky sap (latex) when damaged or broken.
Bright yellow flowers that are approximately 1 1/4 to 2 inches in diameter. The flower stalks are hollow and two to six inches long.
The green leaves are oblong in outline with wavy margins, sometimes sparsely hairy, deeply indented with lobes pointing toward the center of the rosette. Usually two to eight inches long.
The seeds that form the
'puff-ball' are brown, 3-5 mm long with a feathery pappus attached that
allows them to float in the wind for several miles.
