I have a question about lawn fabric. How big an area should I cut out for the base of new shrubs I'll be planting? I didn't know if the fabric is supposed to be snug around a shrub's base. Also, I'll be planting some perennials that are supposed to spread quite a bit (up to 2 ft), so how much lawn fabric should I cut out for them? Thank you!

If you're planning on putting down weed blocking fabric, you'll want to roll it out over the entire flower bed and then cut holes in it to plant your perennials. You'll want to leave a few inches of space between the weed block and the stems of your perennials. If you have trailing or spreading plants, they will attempt to root wherever they touch the ground. You can either slit the weed barrier where you want the plants to root or you can cover the weed block with bark chips and the trailing plants will bury their roots in the bark. Or, you can leave a large circle of earth bare of weed barrier and allow the plants to root naturally. Of course you'll need to watch this unprotected area and pull weeds as they appear, until your plants completely fill the area. Hope this answers your question!
