When to Use Post-Emergent Herbicides
In order for the post-emergent to be effective, it is important that the herbicide come into contact with the plant tissue. When mowing your lawn, allow the weeds to grow for several days after mowing and then apply the herbicide. Doing so will increase the amount of time that the chemical sits on the plant tissue, in between lawn mowings. Always allow several days in between mowings so the chemical can work and infiltrate the weed.
When to Use Pre-emergent Herbicides
If you are planting flowers or growing plants, take caution and remember that a pre-emergent herbicide will burn any germinating seedling it touches. While larger seeds, such as those for large shrubs and trees, can break through a pre-emergent herbicide barrier, small seeds cannot. If you want your annuals and biennials to reseed, don't use a pre-emergent herbicide in such areas.
