My lawn had a lot of weeds, dandelions are the majority of weeds. I tried to pluck them every week but it just got worst and worst as they were growing out everywhere. I received a referral recommendation from a friend stating Green Oasis is very good and effective. So I called them up and they came and performed a thorough weed application on my lawn. Within 3 weeks, I could see a big difference, no more weeds growing out on my lawn. Thanks Green Oasis.
