Come February and March, we all get a little antsy to get out and dig in the dirt. Geraniums can be wintered over to give another season of bloom and more plants for the border. They can also keep you busy so you don't spend too much time with those seed catalogs. Bring plants inside for the winter and grow new plants from cuttings.
Choose healthy geranium plants with lots of branches to keep over the winter. Pot them up and treat them like houseplants. Overwinter the geraniums in the garage or keep them in your bedroom window all winter long. Since geraniums are perennials, plants may be kept inside and continue to grow. After the last spring frost, they can be moved back out to the garden for another year of spectacular blooms.
Pinch the branches of the geraniums back during the winter to encourage bushiness and to keep them from getting leggy. Use the pinched branches to create more geraniums.
Snip the ends of branches from adult plants you are overwintering and strip off all but the end leaves. You should have two or three nodules on each stem. Start as many sturdy shoots as you have.
Dust the ends of the stems with rooting hormone powder and plant them in peat pots filled with a sterile, lightweight planting medium. Keep the soil moist but not wet to avoid mildew.
After about a week, move the cuttings to a sunny window and leave them there to grow until after the last frost, when the plants can be moved outside. Pinch them back once after they root to create another branch in each new plant.
