Flycast, the date of your query is what is confusing me...are you asking about starting a seedling...or maybe in the spring, if you were to wish to move a geranium from one place to another....would it be OK to plant so the earth was up to the leaves....and to that...YES...go ahead do that. Then water well.

If you are asking about how to treat a cutting....The best thing about the zonal geraniums is that they are usually easy to propagate from stem cuttings.

To do so, remove a stem 3"-4" inches long with two or three leaf nodes. Remove the leaves, dip the stem in rooting hormone (not mandatory, but helpful), pot it up in a 2" pot filled with damp vermiculite, and cover with a plastic bag. Place in indirect light. Within 4-6 weeks, the cutting should begin sprouting roots. You can tell whether this has occurred by pulling gently on the cutting. If it resists, there are roots below the surface. The rooted cutting should be potted up in and placed in a well-lighted spot.

Hopefully this has addressed your query....if not..
Have a nice day.

OK, thanks for your help. I wanted to replant because I had planted some seeds that sprouted and grew leggy. The reason being is that they had come up in 5 days and not the 10-20 days that I had expected (I planted them then didn't check them for 5 days). I replanted last night. I think they will be OK. They have nice color and grew more leaves.
