WHAT'S THAT WEED? SERIES

Dandelion

HOW TO IDENTIFY?    

  • YOU KNOW what  they look like 

HOW DO THEY GROW?

  • Long, deep taproots.
  • Spread by SEED
  • Prefer sun and infertile, compact soil.

ARE THEY A PROBLEM? 

YES

  • Compete with other plants for space and moisture. 
  • Seeds blow into other areas including neighbours’ yards. 
  • WILDFLOWER garden is a BETTER source of pollen for bees. 
  • Some people find them unattractive.

NO

  • Improve soil by breaking it up/aerating it.
  • Deep taproots bring nutrients to the surface and make them available to other plants. 
  • Early source of pollen for bees (but
    low in protein and not that nutritious). 
  • All parts are edible but BE AWARE:
  • There are other plants with similar leaves – make sure you’re eating the correct plant. 
  • Dandelions contain latex and some people are allergic.
  • Can be fed to livestock (including backyard hens). 
  • Some people find them attractive. 

HOW TO CONTROL? 

  • Maintain a healthy lawn.
  • Vacuum seeds with shop-vac. 
  • Individual dandelions can be WEEDED – make sure to get as much of the taproot as possible.
  • Weed when soil is moist; use a long, thin weeding tool to loosen soil around root. 
  • Cover LARGE AREAS with cardboard and mulch.
