During the worst summer heat, your plants can parch between the time you go to work in the morning and when you arrive home. And if you want to go away for the weekend, you might have to hire help! Solve this dilemma with ingenious self-watering planters. These containers feature a built-in reservoir at the base. Plant roots grow down into the reservoir and take up as much water as they need . . . while you have time to enjoy the rest of the garden!
