For Mosses and Algae. Hydrated lime: Apply 2 to 3 lb of hydrated lime in 3 gallons of water per 1,000 square feet. Ferrous sulfate: Apply 4–7 oz or 10 oz of ferrous ammonium sulfate in 3 to 5 gallons of water per 1,000 square feet.
Iron sulfate will start damaging moss in a matter of hours and effectively kill it within two days.
Algon Moss and Algae remover/killer
It takes a few days to work but, in our experience, generally kills it all and, what is more, stays on the surface to keep killing new infestations for a couple of months.
Moss control products based on iron and naturally occurring iron substances, such as ferrous sulfate, are highly effective at killing lawn moss by drawing out moisture so mosses dry up, turn black and die.
Chlorine is still one of the most effective killers of algae so doing a super-chlorination of 10-20 ppm of chlorine can go a long way towards wiping out the algae. Liquid chlorine is an ideal shock for algae because it is fast acting and does not add cyanuric acid (CYA) or calcium to the water.
Answer: My favourite solution is to make your own weed killer by combining four cups pickling vinegar, half cup salt and two tablespoons dish soap. Spray on unwanted plants in driveway cracks.
Vinegar is effective against moss because it contains acetic acid. This acid kills germs, viruses, and softens fabrics. However, bleach is more effective than vinegar at killing moss, so you may want to consider another solution.
Chemical moss killers containing ferrous sulphate (also called sulphate of iron) are the most effective method of eradicating moss in lawns. Some chemical moss killers also include a fertiliser, which is useful for lawns where the grass has lost its vigour.
Iron sulphate is one of the most widely used products for the eradication and control of lawn moss.
As much as possible, remove the conditions that moss and algae love to grow in. For example, solve any drainage issues so that moisture isn't lingering on the surface and introduce more sunlight. Have the lawn cored and consider topdressing with gypsum.
In general, mosses are dense, low growing plants with threadlike stems and tiny leaves. Algaes form a more dense, slimy coating that turns black when dry, often forming a hard crust on the soil thus making watering difficult.
In short, a moss is a simple plant, and a lichen is a fungi-algae sandwich. Mosses are multicellular organisms with leaflets made of photosynthetic cells, just as with trees, ferns and wildflowers.
'For the best results, use white vinegar with a solution of about five per cent. However, for a more potent option try a six per cent cleaning vinegar solution. ' Getting your garden ready for summer?
Holding the spray nozzle a couple of inches from the target area, drench the moss with the solution. Make sure not to spray the grass, as the solution can also kill healthy grass. The patches of moss will turn orange or brown in 24 hours and eventually dry up.
Treating Moss: Baking Soda
Products containing d-limonene (citrus oil) are also effective at killing existing moss. Results are usually seen in 2-3 days. With either treatment method, some moss will slough off naturally as it dies. Gently remove the rest with a wire or nylon brush.
In the same way that baking soda can be a spot treatment for black algae, household borax does the same for blue and green algae. Simply use the borax to scrub away algae that's sticking to your pool walls, then use the brush to dislodge it. Follow up by vacuuming up or scooping out the free-floating algae.
Hardware stores and home centers sell products designed to kill moss and algae, but you can save money by using inexpensive chlorine bleach or a non-creamy hand dishwashing detergent, such as Dawn.
Baking soda is an effective way to get rid of moss in your garden and around your home. It's non-toxic, so it won't harm wildlife, and it is relatively inexpensive. Plus, it's easy to apply! Baking soda raises the pH level around moss.
Too much shade for acceptable grass growth is a common underlying cause for moss invasion. Pruning trees and shrubs to improve air circulation and light penetration is a good starting point. Evaluate the site to make sure the proper grass for the conditions is being used. Take a good look at the soil conditions.
Chlorine bleach removes mosses, fungi, and mildew, but it may damage plants, so dilute it before you spray it on your roof. A good formula is to mix one quart bleach with one gallon of water and 1/4 cup heavy-duty cleaner, like trisodium phosphate.
