DESCRIPTION
Tackle unwanted plants in your lawn, landscape, and more with Scotts® MossEx™ 3-in-1 Ready-Spray®. This fast-acting formula effectively controls mosses, algae, lichens, and liverworts. The product gets to work within hours, and does not stain concrete or other surfaces! Apply Scotts® MossEx™ 3-in-1 Ready-Spray® on lawns, ornamental gardens, around homes and on roofs, patios, decks, sidewalks, and more (as listed). It can be used at any time during the year; however, best results are obtained with actively growing moss in the spring or fall. To apply, simply connect the sprayer to a garden hose, turn on the water, and spray, keeping it moving for an even application. Do not use on lawns when temperature exceeds 85°F. During warmer weather apply late in the day. Application during cold weather may delay appearance of moss damage. Applying this product in calm weather or when rain is not predicted for the next 24 hours will help to ensure that wind or rain does not blow or wash product off the treatment area. One 32 fl. oz. bottle of Scotts® MossEx™ 3-in-1 Ready-Spray® treats up to 500 sq. ft.

Shake container gently before using. Connect the sprayer to a garden hose. Turn on water. To begin spraying, point the nozzle in the direction you want to spray.

Range is very limited.
The spray comes out in a fan formation. Couldn’t reach any portion of the house roof. Was able to do the edge of the roof over the garage but could not reach any of the house roof. Wound up using it on the walkway & stone wall.

Simply a tough Mosss season
I have used this product in the past with great success! This year the moss seems to be super strong. I have applied two applications per the settings on the bag with a DLX spreader. I'm finding a lot of extra arm work with raking it out.

This is a fantastic product.
Im an experienced gardener and I love this product. Why? most iron products come infused into large amounts of Nitrogen. Boo. I fertilize my yard already. i dont need that. the Calcium doesnt burn and its not going to kill my grass if i put down too much.Im a person who tries to give my yard the entire NPK range for health over the year. I also give my yard calcium. This product greatly reduces the amount i apply every year. The health of my yard is improving with every use. Im not masking poor health with surplus nitrogen. I live in the PNW where moss is a constant issue. I love the tiny particles. they break down and get into the soil with very little water. Its necessary to put moss kill down many times per year in the Seattle area. This product is a win/win for me.

Not For Roofs !
False claims regarding roof application. Attempting to remove moss from small one story barn roof. Fan produced by nozzle which reaches about 24 inches and from ground at arms length, reaches only the edge of the roof, where the moss is NOT located. “For Roofs” Yeah Right ! The nozzle is TERRIBLE !!!
