    What is the best way or process for keeping unions from developing in your lawn through the cold months? Is there a pre-emergent program to keep this from happening?

    You have to treat them while they are up. I use manor or Tri power. Spray them and then 3-4 days later cut them down. After you spray them , they will start to turn white and fall over this is the time to cut them. Depending on weather, it may take 5 days for them to "curl".

    Sometimes yes you will be spraying them all winter. Some yards may only have a few and then they only get one or two for the rest of the year. Depends on the yard.

    before you spray wild onion's stomp on them!! this breaks the skin and allows the weed control to enter the plant instead of just running off.
