I HAVE READ VARIUOS WAYS TO OVERWINTER PRLEGONIOUMS. IS THERE A SUCCSSESFUL WAY
Nunu, Ideally you should have taken cuttings in July/August and you should keep these frost free over winter. Also I keep a few pelagoniums in the house/conservatory over winter - they can go on flowering but best to let them rest by reducing watering.
Otherwise pot up your pelagoniums, prune them really hard back to about 6" height and keep in a frost free place until spring. Water very sparingly and remove yellow leaves. In spring use unwanted shoots (facing inwards) for cuttings in gravel.
