Q.when is the best time to take cuttings of Geraniums for potting for next year
I have a lot of Geraniums in my garden good strong plants so it would be a shame to loose them all.
I believe you are asking about Pelargonium, aka zonal geranium. It is a little late to be taking cuttings but worth a try. You can also dig your plants up and let them go dormant over winter. Usually plants are put in pots and allowed to dry out. Store them at 40 F if you can. Keep an eye on them because "presto chango" they will start to grow in late winter/early spring. At this time you must water it or lose it. Here is a good article, with a video, on taking cuttings: http://www.bbc.co.uk/gardening/basics/techniques/propagation_pelargoniums1.shtml
