Garden sprayers are tools used to apply liquids, such as fertilizers, pesticides, or herbicides, to plants and gardens. They come in various types, including handheld, backpack, and wheeled models, allowing users to choose one that best fits their needs. Most garden sprayers have a tank to hold the liquid and a nozzle to control the spray pattern and flow. These sprayers can be manual or powered, with some models featuring a pump to create pressure for a more even application. Proper use of garden sprayers helps ensure effective treatment of plants while minimizing waste and environmental impact.
