Pool noodles can hold seedlings in place when sprouting in a hydroponic nursery. Slice the noodles into 1-inch disks and insert the seedlings into the centers.
Poke holes in a pool noodle with a skewer to create jets, then plug one end with foam pieces and secure it with duct tape. Attach it to a hose and water your garden.
To protect plants from extreme weather, create a row cover using pool noodles. Start by planting the stakes a foot apart along both sides of a garden bed.
Attach the noodles from one stake to another, creating an arch, and drape a garden fabric on the foam frame. Secure the ends with clips, or use sandbags or soil for extra security.
Soften a planter's edge so it doesn't damage the vines of plants like zucchini. Cut a pool noodle, slice it lengthwise to create a slit, and slide it onto the edge.
