Since they provide consistent water to your flowers or herbs, you are less likely to kill them accidentally!.

How do self-watering window boxes work?

A self-watering planter consists of two window boxes. The bottom one for the water reservoir, while the top one holds your flowers, herbs, or vegetables.
