I've never been a great one for remembering to water plants. Better to not have to. A really good way to do this is with an automatic watering system. In my case I'm using a drip line system that will provide water directly to the plants:
The watering is controlled by a timer on the hose:
Set to water the plants for 15 minutes everyday at 6am. With any luck, this will be the last time I have to worry about watering them.
