When should I apply weed killer?

Answer by  BeccaBug (19)

Weed killer should be applied either early in the morning or in the late afternoon, especially in the summer. Do not apply it during the heat of the day. Make sure you selectively apply the weed killer as most do not differentiate between weeds and plants you wish to keep in your yard.

If there is an area that you know has weeds every year, you can apply some in the early spring (mid April or early May) to prevent the weeds from germinating. To treat actively growing weeds, you should would typically weed control in the summer, when the temperatures are between 70 and 85 degrees F.

There are two main types of weed killer: pre-emergent and post-emergent. Pre-emergent weed killers are applied to an area before weeds grow and post-emergent killers are applied after weeds appear.
