I've got a small mountain plot that receives a good bit of shade. Raked it w/ my tractors landscape rake 4 years ago & planted clover + a little rye & oats to compliment. The plot did really well for 3 years but this past year started getting thick w/ moss due to the shade it receives. Without removing any of the trees or raking the plot (it's on a hella incline & erosion will be bad), is there any way to get rid of the moss?
