Will a heavy dose of crushed lime kill the onions? HELP!!!!

Denise,

I'm having the same problem too! I just surfed the NC co-op ext.
service and found this advice:


Wild onions are really wild garlic but, whatever the name, they are
cause for frequent calls to the Extension office for assistance. The
best time for treating them is in February or March because the chemical
must be allowed at least two weeks to work before the lawn is mowed.
They are difficult to control and usually require two treatments in two
consecutive springs. Spot spraying individual clumps with 2,4-D amine
herbicide [available in most garden supply stores] works best. Mix 1.3
fluid ounces per gallon of water, or 1.5 teaspoons to a quart of water.
You can add 1 teaspoon of liquid dishwashing detergent to each gallon of
spray to help the herbicide stick to the leaves.

Only mix the amount of spray you will need to prevent disposal problems.
Remember to avoid mowing the tops for at least two weeks, until the tops
begin to yellow and curl, to get the best kill of the underground bulbs.

When using any pesticide, be sure to follow labeled directions.

Good luck!

This is not optional if you want product to work. Some ester formulations of 2,4D may not need a spreader/sticker but most "off the shelf" products will be amine and a non ionic surfactant is a must to wet the foliage of garlic.
