Take your own cuttings
Pelargoniums are easy to propagate from seed and even easier to grow from cuttings. Plants grown from cuttings will bloom within three to six months. If you take cuttings in spring or summer, you’ll see good growth quite quickly. In autumn, when you prune your mature plants, you can also use those trimmings to make new plants. Here’s how:
Choose a strong and healthy mother plant. Use the top part of a stem with growth that has already hardened, but is not woody. The stem must be about 15cm long with three to five nodes. Using clean, sharp secateurs, cut off the stem just below a leaf.
If the stem has flowers, trim them off. Remove the leaves from the lower half, leaving a few leaves at the top of the cutting.
If it is a pelargonium with large leaves, trim each leaf by about a third to reduce moisture loss.
Insert the cutting halfway into a pot with well-drained potting soil. Keep moist but not wet. Place the pot in the shade and move it to a sunny spot as soon as new leaves emerge.
When it has formed enough roots, it is ready for transplanting. Test by gently tugging on the plant; if there’s a bit of resistance, it has sufficient roots. >>
