Personally, I've never understood why people freak out about weeds like dandelions, Creeping Charlie, or clover. What?s the big deal? I think they look nice. A yard or garden that is well-kept, but still a little wild looking is more aesthetically pleasing to any nature lover, I'd say.
Spraying weeds with herbicide is unnatural and unhealthy. Herbicides contribute to environmental pollution, and the weeds grow resistant to them after time. Granted, it takes more work to get on your hands and knees and pull them out by the roots. So consider the option of just letting it grow, au natural. Instead of lording authority over your garden, have respect for the mini-ecosystem existing around your dwelling.
Dandelions have many amazing healthful benefits. They have a history in Native American and Chinese medicine, and today you can find them in teas and capsules at your local health food store. Mainly, dandelion is used as a digestive aid, because it is a natural diuretic.
Instead of constantly battling dandelions, you should join them. And by join them, I mean drink them as tea.
Dandelion Tea Recipe
From the University Of Maryland Medical Center:
Dried leaf infusion: 1 - 2 teaspoonfuls, 3 times daily. Pour hot water onto dried leaf and steep for 5 - 10 minutes.
Dried root decoction: ½ - 2 teaspoonfuls, 3 times daily. Place root into boiling water for 5 - 10 minutes. Strain and drink.
Keep in mind that you should not make dandelion tea after spraying a whole bunch of herbicides on them. This will make you sick.
