Broadleaf weeds are weeds that have leafy appearances and grow in vines or shrubs, as opposed to grassy weeds that have grassy properties. Broadleaf weeds are usually very hardy and can be difficult to kill sometimes. A good herbicide and some careful planning can do the trick, though. The combination of a pre-emergent herbicide and a post-emergent herbicide can eliminate the broadleaf weed population.

How to Spray Weed Control

When spraying a post-emergent herbicide to kill mature broadleaf weeds, you should spot treat the visible weeds before spraying the whole area evenly. This will allow for extra concentration of herbicide on large plants while fighting any weeds that are too small for you to know about yet. Always pick a dry 24-hour period in which to spray a post-emergent broadleaf killer. It's important that the lawn not be disturbed for at least 48 hours after spraying in order for the weed control to take full effect.

Remember that killing all the foliage on a plant does not mean that the plant itself has been killed. Weed roots, especially broadleaf roots, usually dig very deep and several applications of a post-emergent weed control may be necessary to rid your garden or lawn of broadleaf weeds. The only way to get rid of a persistent weed is with diligence.

A pre-emergent herbicide should be used in conjunction with a post-emergent herbicide. If you see a weed, then you can guarantee that weed germination is occurring right under your feet. Germination is ongoing, and you should fight weed germination with a pre-emergent weed control whenever possible.
