Take a piece of rebar and cut with hacksaw to about 1.5-2ft. Drive in the ground with a hammer or suitable tool leaving about 6-8 inches of rebar above ground. I like to use electric fence posts from the local farmers coop. Cut your garden hose to appropriate length and slip over exposed rebar. Makes a nice rolling hose guide whereever you need one. Easy to pull up and move as needs require.
Watering Can Extender:
I have many plants under lights. Some are hard to reach for watering. I cut an appropriate length of garden hose and slip over the spout and it gives me easy access to water those hard to reach plants. I guess it depends on what kind of watering can you use.
