The usual odd dandelion is easy enough to deal with, but I noticed that I was starting to get a lot of what I think was yarrow spreading across the lawn, as well as some mossy areas. This Resolva lawn weedkiller has been great. I spread it just before going on a holiday for a week, so that the dog would not be going on the lawn, and when we returned it was obvious that it was working. The vast majority of the moss, yarrow and anything else non-grass was dying off. The only issue was not realising just how much of the lawn was no longer grass, so there are now some fairly bare patches, but I will reseed those over the autumn and hopefully I'll have a much lusher lawn come next spring! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/61552879-resolva-concentrate-lawn-weedkiller-extra-500-ml](https://www.desertcart.com.br/products/61552879-resolva-concentrate-lawn-weedkiller-extra-500-ml) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-05-27*
