You could cut the long stem off and cut it into sections. As long as each section has a pair of leaves you can root each piece, just as is it were a tip cutting.

Thank you for the response and sorry I didn't see it earlier!

The first cutting is doing well, I think - I did cut one of the leaves in half because I think (with my very limited and new knowledge) that it was too much for the plant to support.

Just to clarify:

So I can take the remaining stem and just cut above each leaf node as far down as I have leaves and plant each piece? Doing that I could get three more cuttings from the stem.
Do I need to wait for the next piece in line to callous over before cutting it off or can I just chop, chop, chop all the pieces at once?

unanswerable question: Where will I put all these cuttings? I'm running out of room because I have dived right into houseplants - plus this year I decided to attempt some cuttings from some of my outside plants and they're in the house as well. I need plant shelves, lol.

I have taken two cuttings off my pelargonium. The first is well rooted (ha, I typed 'rotted' at first) and growing new leaves. The second is freshly 'planted' so hasn't had time to grow yet.

After I took the first cutting, the mother plant grew a bunch of new leaves, including one further down the stem than had previously had leaves. You can see where I took the second cutting in relation to the leaf.

My question is - since these plants can grow from cuttings, can I repot the mother plant and bury some of the stem to help make it less leggy? Will the stem that is buried take root? I plan to repot the mother plant into the 5-1-1 mix (unless it's thought the gritty mix would be better for the plant).

Will that cause an issue with rot because it has two (3?) cut-off stems low on the plant?

Or - will cutting it back again potentially cause it to start growing new leaves further down the left-over stem, like it did after the first cutting?

Thank you!!!
