What Do Lawn Care Companies Spray on Lawns?

Lawn spraying is a practice that has been around for as long as humanity. But still, you may wonder, how much to spray yard for weeds. Besides, what do golf courses use to kill weeds?
Before we look at the answer to that question, let’s see what do lawn companies spray on lawns.
1. Lawn fertilizer
Fertilizers are vital in the grass to replenish essential nutrients lacking in the soil. Always apply the proper amount, as too much fertilizer can damage your grass. Also, it can contribute to runoff, contaminating streams, and groundwater.
Lawn professionals use Milorganite as it has slow-release and water-insoluble nitrogen, which feeds your grass for an extended period.
2. Herbicides
The recommended herbicides for lawns are selective, as they only target and eliminate specific weeds. If you use a non-selective one, it will kill weeds and your entire lawn.
The two herbicides you can use on your lawn as either granule or liquid are pre- and post-emergent. You should apply pre-emergent herbicides before weed seeds germinate, as it eliminates weed seedlings as they develop. Spray post-emergent herbicides on your lawn when the weeds are already growing.
3. Insecticides and pesticides
Insecticides and pesticides are other commercial lawn care products professionals use to keep the grass healthy. Use insecticides to kill harmful insects and pesticides to eliminate critters.
Select these chemicals carefully to avoid buying the ones that can harm pets and beneficial pollinators.
4. Fungicides
Use fungicides to kill or inhibit lawn fungus from growing. Some lawn fungi include diseases like leaf spots, dollar spots, mushrooms, and molds.
