How to Transplant Geranium Cuttings

Fill a 4-inch-deep plastic pot with a mixture of equal parts perlite and coir. Leave 1/4 inch of space above the rooting mixture.

Pour 1/8 cup of water onto the rooting mixture to moisten it to its entire depth. Let the water drain off for a few minutes before potting the geranium cutting.

Harvest a 3- to 4-inch-long cutting from the tip of a non-blooming geranium stem. Select one with mature leaves at the base and a cluster of young leaves at the tip.

Sever the geranium cutting just below a pair of leaves using floral snips or by pinching it off with your fingernails. Pluck off and discard the leaves from the bottom inch of the cutting.

Stick the defoliated end of the geranium cutting into the prepared rooting pot. Press it into the rooting mixture until the lowest remaining set of leaves rests on the surface. Press the mixture tight against the stem.

Place the pot inside a sealable 1-gallon plastic bag. Seal all but 1 inch of the top to allow for evaporation.

Set the pot on a north- or east-facing windowsill where it will receive bright, diffuse light. Avoid west- or south-facing windows because the light will be too intense.

Drizzle 2 or 3 tbsp. of water around the base of the cutting whenever the soil feels dry. Maintain light, even moisture in the rooting mixture for the best results.

Check for roots in three weeks by tugging gently on the stem near the base. Feel if the geranium cutting is anchored to the soil by roots.

Transplant the geranium cutting into a 4-inch-deep plastic pot filled with standard potting soil once it has rooted. Place the rooted geranium cutting under similar conditions as the parent plant.
