A question about using landscape fabric.

Q. My lawn maintenance man wants to put down landscape fabric to stop weeds from coming up around my shrubs. Do you think that’s a good idea?

A. I’m not a big fan of landscape fabrics and similar weed barriers, for the following reasons:

• They might prevent weeds from germinating beneath them, but permeable ones don’t prevent seeds from germinating on top and growing down through them; 
• Weed barriers on slopes might not let water perk down through them fast enough, instead letting the water drain where it shouldn’t; 
• Edges of weed barriers can become exposed and tangle in lawnmower blades. 

I much prefer applying plenty of organic mulch.
