A soaker hose is a hose with small holes that you strategically placed around garden plants. Once turned on, the water is emitted from the holes and waters the plants near the ground. Most gardeners who have a soaker hose have an above-ground one. While you can clean a soaker hose, know that due to the way it is used, it will only get dirty again. More importantly, check your soaker occasionally to make sure the holes have not become clogged. If the holes are clogged, you need to clean them out to make the most out of your soaker hose.
Lay out your soaker hose flat along a clean driveway or sidewalk. You can also lay it out on the grass if you don't mind the outside of your hose staying dirty.
Turn the hose on and check for clogged holes. Lay a stick or another marker by the clogged holes and turn off the hose.
Insert a pin or small pointed nail into the holes to dislodge the dirt or whatever is clogging the holes.
Turn the hose back on to make sure the holes are no longer clogged. Repeat the steps as necessary.
Use a second hose without holes to rinse the soaker hose clean, if desired. Turn the soaker hose over on the other side and repeat. Allow the soaker hose to dry before returning it to storage or winding it back up onto the hose rack.
