Answer: This is a tough weed to combat! It has many survival tactics that make it a successful plant. Just don't let it go to seed, as some seed remains viable for over 50 years! Apply heavy mulch between your plants (Barbara Pleasant, author of "The Gardener's Weed Book", says carboard covered with leaves works great). You'll have to be vigilant and pull up any that peek around the mulch barrier. Try to dig out the roots if you can. Hope this helps!
