   W: Here's a quick gardening tip from me, Sara Martin, your guide to better gardening. Many of my followers complain that after working in the garden, the rest of their lawn is a mess. They say the weeds they've pulled or the dead flowers and branches they've removed are scattered about, and oftentimes cleaning this trash is just about as time-consuming. Here's the quick fix: Before you begin working in your garden, spread out some newspaper on the ground, close to where you re working. Toss all your clippings, weeds, whatever onto the newspaper. Then, when you're through, just fold it up and put in the garbage. A good friend of mine prefers to use a sheet designated for the garden, but I think using newspaper is more efficient. Use this tip to spend more time on gardening and less on cleaning up!
