This year I have decided to propagate some geraniums by planting cuttings at the house on the coast which has a mild climate.
I simply cut off the main stems from the parent plants and then protected the originals with garden fleece so that they might survive the winter. I made cuttings about 15cm long, making the cut just below a node. I left one healthy leaf on each cutting. I didn’t use any cutting hormones. (because I had forgotten to buy any). I used a plastic tray module.I did this on the 28th December 2011. They were left in the open air. The climate is mild and rarely goes below 10C.

The picture below shows the overwintering geraniums from last year and new ones being propagated. Last year’s ones were a big success.
Propagating geraniums is easy. The most important thing to do is spray them every 3 weeks to stop the stem boring caterpillars.
