The first step in dividing a Geranium is to dig up the plant. Use a square headed spade to dig around the plant's root ball. Undercut the roots of the plant and lift it out of the ground. Shake the excess soil from the plant's root ball. The best time to divide aGeranium is after the plant has died back in late fall, or early spring before new growth has started.

Trim off any old vegetation still left on the plant.

Grasp the root ball on both sides and twist. Often times Geraniums will show a tendency to want to break apart in a certain place. This is where you will make your division. If it doesn't feel like it wants to give in any particular place, make your division right down the middle.

Use a sharp knife to cut straight down through the root ball. The number of divisions you make is dependent on the size of the plant. Regardless of the size of the plant, you want to avoid having more than two cut sides on any of the divisions.

Try to leave 3-5 eyes on each division. New growth will form from each of the eyes when the plant starts to grow. The more eyes you have, the larger the resulting plant will be.

Each division should have a healthy root system. The larger the root system, the larger the plant will be next season. Plant the divisions as soon as possible after dividing. The eyes should be about an inch under the surface of the soil. Mulch everywhere around the plant except directly on top of the crown to avoid rotting.
