The seeds can germinate without a waiting period and start producing new plants immediately. 2
Dandelions present challenges for lawn owners on several fronts. These pesky broadleaf weeds are perennials that survive winters to come back larger and more resilient year after year. Survival gets a boost from strong, sturdy taproots that can grow 10 feet deep or more—well out of the reach of dandelion diggers or shovels.
