但是我觉得MOSSKILLER有比较强的化学成分。所以，能不用就不用。下面是我搜得另外一个文章。观点是不主张用MOSSKILLER。 4 h4 x$ t9 v3 N7 @3 ^: t/ h

Q; My lawn is full of moss again. We put down moss killer last year and the year before that and overseeded. The lawn looked good for a while but now it is full of moss again. What to do?

8 J; G, t; x/ t% M: m2 [SW. I never recommend using moss killer. It goes against one of the most important rules of gardening to work with nature and grow the right plant in the right place.2 A# Z7 [" i: w7 z, e, Y
Even though today's moss killer is more organic and uses iron sulphate to kill the plant rather than the chemical dichlorophen, I am still very much against the whole negative, destructive process. I can't believe that some experts are still telling people to use it.6 l! [9 B( q" Z/ |2 D
The first thing to realize is that moss is a perfectly good plant. In Japanese gardens, it is encouraged because it is regarded as desirable and beautiful., H9 |) V/ l; y' N1 E6 B
You might start by asking yourself if you can live with moss. Under trees and rhododendrons, it can look lovely. It is, of course, not practical in an area that is played on a lot.
/ c6 v9 g( W& k- T( z" v$ t D' vThe next question to ask is why moss is growing in the first place. It is usually because the soil is very acidic and compacted or drainage is poor or the area receives inadequate sunlight. Often the reason for moss in a lawn is a combination of all these factors." y* t4 q% [5 `; A
Grass loves the opposite conditions: slightly alkaline soil, a minimum of six hours of sunshine a day, and well-drained soil.

I8 I) aIf you want to grow grass instead of moss you have to change the conditions: spread lime to sweeten the soil and raise the level of alkalinity; aerate and brush in sand to improve drainage and reduce compaction; and raise the light levels by removing a few branches from trees or shrubs that are shading the area.
% C& L% E5 W+ D/ H8 e; [, |If you must use moss killer, use it once only as part of a renovation program. To be effective, moss killer that comes in granular form must get down to the roots of the plant. Don't just spinkle it on the spongy top of the moss. You need to scar the moss with a spade or hoe and then apply the product.

But if you are doing this year after year you are wasting money and not dealing with the real source of the problem. Moss killer also ultimately damages the structure of soil, destroying the natural balance of organisms. So it is environmentally destructive, in my opinion, to keep using it.
' U# N( ^4 O; v3 c0 }Another positive solution is to redesign the area and grow plants that don't mind moist, acidic soil and low light levels. Hostas, ferns, bleeding hearts, azaleas, kalmia, rhododendrons and hydrangeas are all good candidates.
