RFP Guide: What type of weeds do you have?
RFP Guide Part II: What type of weeds do you need to target? Annual or Perennial?
"An essential part of identifying grassy weeds has to do with their life cycles." (“Identifying and Controlling Grassy Weeds | TruGreen”) Does your RFP or SOW target the weed issue you have currently?
For example, your team may be able to hand-pull a few annual weeds, but perennial grassy weeds have a deeper root structure that can give rise to new weeds—even if you no longer see the weeds in your lawn.
Do you have the right SOW for the different life cycles of weeds in your lawn?
?Annual weeds. These weeds live for only one season and are typically easy to control because they lack the complex underground structures needed to spread new plant growth through creeping roots. Still, annuals produce tons of seeds that can infest and dominate your lawn under the right conditions.
Summer annuals. These grass-like weeds begin to grow (germinate) in the spring, mature in the summer, and then produce seeds and die by the fall or first hard frost—an entire life cycle completed within 12 months.
Winter annuals. These weeds overlap two calendar years but last only 12 months total. They germinate and develop from late summer to early fall, remain semidormant during the winter and then flower in spring.
Perennial weeds. Perennial grassy weeds can germinate and spread from seeds, but they also produce a root structure (tubers, bulbs or corms) that can birth new weeds from your lawn’s surface (using stolons) or from underground (using rhizomes).

Biennial weeds. These flowering plants generally live for two years. The first year consists of leaves, stems and root growth, followed by winter dormancy. In the second year, biennials flower and produce seeds, thus completing their life cycles.
The biological similarities of turf grass and grassy weeds make both susceptible to control methods. For example, spraying crabgrass killer at the wrong time can kill your grass seeds. Instead, aim to control grassy weeds by keeping your lawn dense and healthy so they don’t stand a chance. If these turf grass imposters have already invaded your lawn, you can try a few other tactics to weed them out.
As you can see there are many types of weeds to target and the lawncare program you have in your SOW needs to address these weed challenges. At TruGreen National Accounts we can help, as your partner we will customize and deliver the correct program for your property. We take care of the science, so you don’t have to. Let’s talk.
