I'm terrible about remembering to water plants and therefore have never had a successful garden. My brother, however is an amazing gardener and took pity on me and my crispy dead plants. He created a garden for me using drip irrigation, a programmable watering timer, and lots of mulch...which means it pretty much takes care of itself. I am happy to report that it is flourishing and all I really have to do is go pick my veggies!

The completed garden - though this was about a month ago and the plants are huge and flourishing now.
