For immediate results and easy application, try liquid fertilizers. The nutrients in liquid fertilizers are immediately available to plants and are less likely to burn the roots and leaves than granular fertilizers. Purchase bottled liquid fertilizers in a variety of formulas (vegetable, houseplant, lawn) to suit your gardening needs or try organic liquid fertilizer such as fish emulsion. Liquid fertilizers are more expensive than granular fertilizers and need more frequent applications because they quickly break down in the soil.
Attach a hose and nozzle to the liquid fertilizer spray bottle for fertilizing large areas. Many liquid fertilizers come in an easy-to-use spray bottle.
Turn on your hose to a medium flow. Spray your garden or lawn area with the nozzle. The water automatically dilutes the fertilizer to the proper amount for you.
Mix liquid fertilizer with water in an old pitcher or watering can according to package directions.
Apply the fertilizer to your houseplants or potted plants at the rate recommended on the package.
Rinse your container with water before storing.
