newbie question: hoeing
This seems so basic, but I'll ask anyway. I put down a nice layer of fine bark mulch around the shrubs and perennials in my garden in the fall. Now I'm getting the beginnings of weeds springing up, including hundreds of tiny maple shoots. I have read that the easiest non-chemical way to get rid of weeds is to hoe them up while they're still tender in early spring. So: do I rake the mulch aside or can I hoe right through it? I don't want to mix the mulch into the soil and ruin its purpose. But I also don't want to give myself unnecessary labor.
