It indicates a soil problem, which is sometimes 'sour' (acidic) soil. It can also be poor drainage, too much shade, or poor fertility. Sometimes it's a combination of these problems.
You will need earth+moss to get grass.
Unfortunately, usually this is not the case. Moss usually grows in areas where grass doesn't grow, due to the soil conditions. By simply putting proper soil over the moss will not solve that problem.
Soil + moss
Thatch is the debris of old grass, cut grass and moss on top of the soil at the grass roots. If left unattended it will stop moisture getting to the roots and your lawn will suffer.
Can I use old grass clippings, lime, sulphur and peat moss mixed with mulchy soil to create a good soil bed for twenty rhaspberry plants?
Moss breaks up the soil and then it decomposes and fertilizes the soil
Moss grow in all sorts of places they grow in soil that you use to just plant flowers with but smooth soil
No, not always. Moss is acidic - yes, but having moss grow is not usually a sign of acidic soil. To grow moss in your lawn, all that is required is insufficient sunlight, low soil fertility, compacted soil, dampness, low pH. If moss is growing, it is more likely a problem with soil compaction.
No! They do not. It is SPHAGNUM.
in plants and soil
Sphagnum moss is added to garden soil because it helps the plants in the garden grow.
After a good rain (or soaking), hold moss down with one hand while gently pulling weeds out through fingers with other hand. Apply sulfur to moss (makes soil more acid which moss likes but grasses don't). Keep watered (encourages moss, makes grass roots shallow and "lazy") Don't use roundup. Bad for environment - killing and mutating little froggies that eat mosquitoes, etc. Good luck. It will be beautiful
