Evergreen complete 4 in 1

I used this last year and thought it was good. I noticed that I over applied in one area which turned the lawn black.

Hi OP, it's a very good product, I use it annually, my Lawn prone to moss growth over winter months. It has the added benefit of controlling weeds also.

My advice, now the frost threat has receeded is to do a tight lawn cut first when lawn dry and collect clippings.

Now spread the 4 in One, I generally do this in the afternoon /evening, best avoid direct sun when spreading. Leave it for a day or 2, if it's dry, I'll hose lawn after two days, helps with soil absorbing the 4 in 1, you'll notice moss going black almost immediately.

With a leaf rake, loosen the dead moss around your lawn, the blackness you refer too is temporary. Be sure to spread evenly, no clumps as you'll damage lawn.

After a week, I would do the next lawn cut with box, this will remove loose and dead moss. Another good hosing of water and your done.

Avoid when applying.

Debri, loose clippings, clean lawn best when applying.

Frost (Wait until risk subsides)

Strong sun light, spread in late afternoon, evenings to avoid burning of healthy grass.

Drying out, after spreading, if there is no rain by day 2, I'd do a gentle hosing of water.

Late April best time and before weeds start to flower.

All of the above based on my experience of using the product over a number of years, finally watch out for special offers, outlets discount around now, 2 bags for a reduced price. If not using full bag, seal & store in dry place.

Yea its very hard to find and getting more expensive.

is mobacter better?

Are larger bags (cheaper by quantity) available? Or a similar formula marketed under a different name/brand in larger size?

I've only seen 400m² bags sold but looking for about 5 times that, which works pretty expensive if using every year.

When moss goes black is it best rake it out or is it OK to leave it and it go away itself?

Mixed reviews on that

Mobactor is a very different product.

@The_Kew_Tour You can rake the blackened moss if you wish but I just leave it as there's too great an area to rake. For a small area I'd rake.
