Colored plastic mulches are the result of university research, which has shown that certain vegetables have higher yields when grown on colored plastic mulch. The increased yields are most pronounced with plants growing under less-than-ideal conditions, such as less than six hours of sun daily. Red is the color for tomatoes. Other colors include green or blue for melons, silver for peppers and blue for summer squash (like zucchini or patty pan) and cucumbers.
Creating a simple, low-cost garden path doesn’t have to be difficult.
Easy Solution: Remove existing grass and cover soil with a layer of thick cardboard (for weed control), securing it with anchor pins pounded into soil. Top with a layer of straw. This type of path works easily in vegetable gardens or perennial borders. It’s also easy to upgrade later to a more formal hardscape material.
