Buying advice

When choosing a weed killer consider the type of weeds, the area you need to treat, and whether you prefer a selective or non-selective formula. For lawns, a product that feeds grass while killing weeds (like Scotts Turf Builder) is convenient. Organic gardeners should stick with acetic-acid options such as Green Gobbler, but expect multiple applications. Always read label instructions, wear protective gear, and avoid applications before rain or on windy days.
