Getting rid of Dandelions

How to stop dandelions in their tracks

1) Mow, Mo' Often:
When dandelions are blooming, mow frequently to prevent the yellow blossoms from maturing into seeds.

2) Root 'Em Out: 
Dandelion plants can't be eliminated by yanking off the tops, but they are easily dug out by hand. A dandelion digger is a specialized tool that removes a wide variety of individual weeds and their roots, with little soil disturbance. The tool looks like a large screwdriver with the "business end" resembling a fish tale. It works by maneuvering it in the soil, parallel to the tap root. With a small pivot, it's easy to lift the entire plant, root and all (that's the theory at least), from its stronghold.

If you raise chickens, rabbits or other types of critters, dandelions are a favorite green. Remember, they're chock-a-block filled with nutrients, so they're a nutrional boost to their diet. And you can't beat the price.

3) Poach Them: 
As a low tech weed control, pour boiling water over dandelion plants. The neighbors might think you're crazy, but in 2 or 3 days the plants will look like a herd of elephants walked over them. Incidentally, this method is also effective against orange hawkweed. However, if you've got a large area, the best way to control them is to smother them. This is also known as sheet mulching.

3) Mulch Methods: 
Since light increases germination and plants need sunlight for photosynthesis, smothering plants will eventually kill them. Make your own weed block by covering plants with cardboard or black plastic and weight it down. If you are concerned about the aesthetics of cardboard or plastic, you can spray paint it to match the surrounding area (ha ha) or cover it with grass clippings, compost or bark mulch for a nicer look.

4) Pickle Them: 
A 5-percent concentration of vinegar, similar to that found in household vinegar, is an effective weed killer against annual and perennial weeds such as dandelions, foxtail, velvetleaf, smooth pigweed and thistle. It works in the garden or greenhouse.

When applied to the weed foliage, the acid in the vinegar acts as a contact herbicide that kills the plants but does not persist in the soil or cause water or other pollution. For older perennial weeds, you may need to apply vinegar more than once. Try heating the vinegar for added punch.

5) Apply Corn Gluten Meal
Here is the ultimate organic weed and feed. Developed by Iowa State University, corn gluten meal (CGM) is a yellow powder created as a by-product of milling corn, is primarily used in farm animal feeds and dog food. It is also used as a "pre-emergent" weed control for lawns. A pre-emergent, such as corn gluten meal, prevents roots from forming during seed germination. If a root can't grow, the seedling is unable to obtain water or nourishment from the soil. Thus, it will dry up and die.

To control dandelions, it is best applied to the lawn about 4 to 6 weeks before weeds germinate. If you missed the deadline, don't worry. Not all weeds sprout at the same time, so you may want to apply corn gluten meal a few times during the growing season. Best of all, the nitrogen in the meal will keep your lawn green and healthy. By the way, corn gluten meal is not the same cornmeal you make muffins with. Cornmeal for baking is made by grinding dried corn kernels.

Where can you buy the stuff? Go to your favorite garden center or nursery, or through the mail order supply company Gardens Alive! or call 513-354-1482 (near Cincinnati, Ohio). They pioneered the use of corn gluten with two products: Wow, which is pure corn gluten, and Wow Plus, which has added natural fertilizers.

6) BBQ Them: Some consider it a last resort, but a weed burner torch is effective against dandelions and other perennial weeds.

7) Be Sickening Sweet: Mae West used to say, "Too much of a good thing is wonderful." In other words, improve your soil. Ann Lovejoy, author of "Ann Lovejoy's Organic Garden Design School," told me how she got rid of horsetail by improving her soil with compost and mulch. Weeds, which often prefer poor, acidic soils don't like the good stuff. The same works for dandelions and other pesky weeds. Not only will they be less apt to take root in the first place, but when the soil is fluffy, they're easier to pull!
