DIY drip irrigation system: bury a milk jug with holes drilled in it next to your plants. Stick the hose in the top of the jug and fill with water. Also works for feeding: add a scoop of fertilizer into the jug and add water.
Drip irrigation- I do this every year and it works great! Especially during a long Texas drought- less water waste. The only thing that kept my plants going, and once the plants get growing they hide the bottle.
