You still haven't explained it very well but I went back to your last post to get a clue.
What you are trying to do, is remove the withered leaves etc . from last years strawberry plants. That was a job you should have done November/December when the plant was fairly dormant.
The plants may already have some new growth on them, but don't worry, just pull the old leaves off and your plot will look a lot tidier with the brown leaves gone. Strawberry plants are like weeds, whatever you do they always seem to re-cover.
