The answer to 'best weed control' is to use a combination of preventive and active methods to effectively manage weeds in your landscape. This includes using pre-emergent herbicides to prevent weed seeds from germinating, hand-pulling or spot-treating weeds as they appear, and maintaining a healthy lawn or garden that can outcompete weeds.
Pre-emergent herbicides should be applied in early spring before weed seeds germinate, and reapplied according to the product instructions, typically every 3-4 months. Hand-pulling weeds is effective for small infestations, but for larger areas, spot-treating with a selective post-emergent herbicide can be more efficient. Keeping your lawn or garden healthy with proper mowing, watering, and fertilization will also help prevent weed growth.
