In the spring she soaks them in pails of water for a couple of hours and then re-pots them. Much too much work for a Lazy Homeowner.

Geraniums are among the most popular flowering plants.
Outdoors, they are used as annual bedding plants, in hanging baskets, in pots and in window boxes. Indoors, they are cultured as houseplants in sunny locations. Common geraniums are actually members of the genus Pelargonium, while members of the genus Geranium include native wildflowers and herbaceous perennials. Pelargonium x hortorum is the common geranium. Flowers may be single or double, are clustered into heads, and may range from red, pink, salmon, and white.
