Ripping Out the Weeds
Like this rock garden at the front of the house. It's right next to the front door, so it's the first thing you see as you walk up to the house. Not a very pretty sight to welcome you home when it's full of weeds.
But the problem is that while you get the majority of it in one pull, the roots and some of the shoots are left in the ground. Underneath the top, visible growth are clumps that will have to be pulled out by hand.
That means a second pass through the garden. You can't just give it a quick once-over of weeding and call it a day. The roots that are left will continue to grow, and soon this garden will look exactly like it did today when I started.
