Best time of day or weather to spray weed control like Round up or Weed B Gon.
I remember someone mentioning there was a better time to spray so that the green leaves absorb the liquid but I cannot seem to find it in the archives.
I would not use Round-up. Toxic to everything, including humans. Going green, like using vinegar is better for you and the environment.
@Angela K- BAD NEWS...Your Hands ! I put a book on cd and sit down and commune with nature ! LOL It is a pain but when done thoroughly at the beginning of the season, that takes care of it, for the most part. I always wait and put down my new mulch afterwards, then DONE! I have gravel paths around my flower beds. That is where I use it. Also where you would have pavers.
You can use the 5% or 9% white pickling vinegar found on grocery store shelves. It will probably be plant based. You can also find 20% strength which will probably be petroleum based but is still better to use than Round Up. Add 2 ounces (4 tablespoons) of orange oil plus a squirt of liquid dish detergent. (That helps it stick to the plant.) Use in the hottest part of the day.
I used a bottle each of white and brown vinegar in a garden sprayer yesterday. It was in the 80's here, and within two hours the weeds were turning yellow. Haven't looked yet this morning. So far so good though.
Well, the vinegar doesn't kill my tough hillbilly weeds, folks! It stunts their growth a few days but then they come back stronger than ever!
Don't plants have different biochemical processes during different times of the day, though? Wouldn't that affect how RoundUp works?
Spray only when it's full sun and not due to rain within 24 hrs. Roundup works fast. Be careful when spraying close to shrubs and flowers. Always best to just pull those.
I have tried the vinegar solutions and have had limited results. If you are killing tough weeds especially some that tend to be woody or have a waxy coat on the leaves, Roundup brings good results. It is impractical to try to use home remedies when you are doing large areas. Just be responsible and use as directed to prevent damaging surrounding plants.
