First and foremost, it is never recommended to use a pop up canopy in stormy or excessively windy conditions. If only light to moderate winds are expected, there are several ways to effectively anchor a canopy. If the canopy will be set up on soft ground, the best way to anchor the canopy will be to stake it at the legs or drive stakes near the base of each leg and tie back each corner with a rope or strap. Anchoring the ropes or straps higher up at the corners of the tent will have the greatest effectiveness. For hard surfaces, many manufacturers offer canvas strap on weight bags and weight plates that are designed to attach to the base of the canopy legs, adding the needed ballast. For more open environments where moderate winds might be encountered, it may be necessary to use 5 gallon buckets filled with sand, dirt, or water.
