Ideally, you would stop difficult weeds before they even appear, but pre-emergent weed control is merely one part of lawn weed control. TruGreen® PhD-certified specialists know that it takes a mix of practices in order to help guarantee elimination of difficult-to-control weeds, which can be either annual or perennial, and cause problems for different reasons.
- Difficult-to-control perennial weeds: These weeds survive and reproduce even in adverse conditions. They may rely on bulbs, rhizomes, stolons, tubers, or thickened storage roots for survival between seasons and are hard to eradicate.
- Difficult-to-control annual weeds: Annual weeds can't survive underground from year to year, but some emerge at times of the year when pre-emergent weed killers aren't active. Furthermore, they might also be resistant to post-emergent treatments.
