I have a large planter in the front yard that measures about 6x20. I just weeded it and I don't think I'll be planting anything until next year. Every year I do this, by the time spring rolls around, I have a tonne of weeds that I have to remove again. I'm always amazed at how many weeds accumulate throughout the fall and winter. This year, I decided that I'm going to landscape fabric the top of the planter and hopefully this will stop the weeds from coming back in the spring. I went to Northwest Landscape and bought two rolls of landscape fabric measuring 3x25' for about $10 each. I asked a stocker where to find the landscape fabric and he pointed me in the right direction. As an aside, this store carries just about anything that has to do with landscaping. I was in a bit of a rush so I didn't have much time to look around.
