Doing a second very thorough weeding before putting mulch down. There are acres of meadows full of weeds that scatter seeds everywhere and it is virtually impossible to keep ahead of them.
I am using animal bedding wood shavings. Laying it several inches thick.
This bed was done in the fall and you can see that the bedding turns a darker more natural looking colour. There were maybe a dozen little weeds in this bed vs thousands in the others.
