              Pros
              • Easy to use

              • Inexpensive

              • Long-lasting

              • Eco-friendly

              Cons
              • Not 100% safe, so lawn owners should handle with care and wear a mask recommended.

              The Green Gobbler Vinegar Weed & Grass Killer is perfect for moss killing tasks and for owners who have a reasonably modest budget.

              First of all, this liquid moss killer is derived from corn and smells good which is ideal for organic use. Without glyphosate, a poisonous ingredient that can cause genetic mutations and cancer, it is also quite safe for pets and children, especially with no toxic residue.

              High capacity is another focal point to help the moss kill chemicals to meet customers’ expectations. With 20% of acetic acid included, the substance can eliminate stubborn moss in a few hours and lead to a significant result after 24 hours.

              Indeed, the water-soluble moss killer is very easy to spray on, which makes the moss rapidly wilt and die. With 1 gallon, you can spread on 1.200 square feet, and there is no dilution required. Some consumers claimed that they could dilute the vinegar slightly with water to stretch it out.

              The only thing you need to take note is that the vinegar is so powerful that it can degrade the soil structure. Therefore, you are not supposed to pour directly on the soil and wear a mask and gloves when using.

              How To Choose The Best Moss Killer For Lawn?

              Moss is one of the two reasons that prevent grass development. Moss infestation is supposed to be tackled with some solutions like raking up, mowing, applying moss control products, improving drainage, and fertilization.

              Now, we recommend buying tips to choose the best moss killer for your lawn as below.

              Firstly, please take consideration of the types of moss killers that you intend to purchase. Which do you prefer: a ferrous sulfate one or an organic product?

              Ferrous Sulphate is an iron-based chemical element, which promotes grass growth and reduces weed and moss development. It enables the ground to seep in more and provide adequate nutrients.

              Organic moss control products are eco-friendly and safe for pets and children's health. Also, it keeps the lawn healthy and gives long-lasting results.

              Because ferrous sulfate gives a quick result in a short time, you need to repeat moss out treatment regularly to prevent your lawn from moss returning. On the flip side, natural substances give a better result for long-term use with fewer applications.

              Secondly, the size of the lawn is a decisive factor before buying. If you own a large lawn, it may have widespread moss infestation, you can consider a large capacity moss killer which can cover your yard thoroughly.

              Last, the proper tool to help you cover the moss control is also essential. If the moss killer is water-soluble, a sprayer hooked into a hose can deal with it well. On the other hand, if the moss control product is granular, you can choose a spreader to dispense your lawn quickly and accurately.

              In short, make a choice when you have already mastered the key factors to identify which product fits your goals.

              FAQs

              What is the best time to apply a moss killer?

              The best time to apply a moss killer is when the moss is wet and actively growing. Remember to apply it before rainy days to have the best results.

              When do I need to rake out the moss after applying a moss killer?

              Depending on each product’s capacity, but on average, you can consider one or two weeks after application.

              What can I do to prevent the moss from coming back into my lawn?

              First, you can perform a soil test to check your soil PH. If it is 1PH or lower, it is a good condition for moss growth; you need to apply a moss killer.

              Second, you can mow the lawn regularly to keep your grass healthy and easily identify moss appearance. If moss returns, you need to reapply a moss control product.

              Third, it’s necessary to feed your land to ensure it meets the lawn’s need because inadequate nutrients lead to moss development.

              Last, aerate the soil to allow the top layer to be less compacted, and promote healthy roots.

              Can I apply moss remover just to the most affected parts of my lawn?

              Yes, you can if you ensure the rest of your lawn is free of moss. You can adjust the amount of the moss remover to spray or spread on different soil conditions.

              What precautions should I take when using a product containing iron sulfate?

              Iron sulfate or ferrous sulfate is available as granular or water-soluble products. It’s easy to cause toxicity if you overuse it. If a human or pet ingests the material, they can get gastrointestinal irritation.

              If your cat is exposed to an iron-based product, you are supposed to wash its fur and feet with water to remove the material from it, or veterinary treatment is required if it is worse.

              Conclusion

              Every moss control product has different strengths and shortcomings. Anyway, we recommend you buy these moss control chemicals because all of them have much value. Choose the best moss killers for your lawn, and have a nice trip!
