Hello Binky,
Ivy geraniums or pelargoniums are no more difficult to manage than most of the other types of geraniums. Personally I keep all my geraniums in their pots or baskets in a well lit, frost- free environment, but not in direct sunlight, from Autumn to early summer, the roots are kept just moist. This system works for me.
When rooting geranium/pelargonium cuttings I do NOT use rooting hormone, liquid or powder. Just insert the prepared cutting into a mixture of potting compost/perlite or vermiculite, water and allow to drain. Do NOT tent or close up the cuttings but keep them in good light at about 15-20 degrees Celsius. If you treat pellie cuttings with rootin hormone or tent them they tend to rot.

Hope this helps

Ron
