If they where mine. I would cut the two taller ones tops off down to where they start to show the white/silver color. The tips and leaves will most likely die, leaves will drop off. They do not need the tip to grow and most times the tip being such young wood will shrivel up.

Not sure that a rooting hormone would be useful diluting it in water. I usually add a 1 tsp of H202 (Hydrogen Peroxide) to the rooting water to keep the water from going slimy.

Getting nice Lenticels (nodes) starting on them. Change the water frequently and check bottom of stems for any sign of rot. Cut it off.

Pot up when lenticels get 1/2" or so. Some do not wait even this long. Make sure the soil is very free draining and add some extra Perlite to make sure it is. The cutting can be watered in once potted up, but do not keep wet. They root in water, but if kept too wet in the soil they will rot.

Look very nice.

I personally would leave the new growth in the leaf base, as the top is snipped off. Any that form down in or around the water could be removed. If the leaves fall into the water and rot, they will make murky water.

They are looking very good. Replenish the water every couple days to keep fresh.

I usually remove the largest leaves and leave the smallest and growing tip. On some cuttings like harder wood I just take the cuttings along the stem and strip off all leaves.

Go ahead and pot them up in 1-gallon pots, preferably with a good potting mix that has a little fertilizer to get them started, and is heavy on the peat moss (like Miracle Gro). Keep them inside this winter. Don't keep them too wet, but don't allow them to dry completely out either. They'll drop most or all of their leaves, but that's o.k. You want them to concentrate on making roots so you can pot them up into larger pots next spring.

When the outside temps are consistently above 70F during the day and 50F at night, put them outside, still in their 1-gallon pots and start fertilizing them. I like to use timed-release fertilizer for blooming plants, because it helps them make roots also, and doesn't burn the tender winter roots with too much fertilizer. You can also use 1/2 strength liquid fertilizer.

Once they get a substantial amount of new leaves and start drying out more quickly, you can pot them up into 5 gallon pots and start fertilizing them full strength with a general all-purpose fertilizer until they get a arger, then start with the bloom fertilizer to encourage them to "Y" and bloom. Remember, they love lots of water and fertilizer during the main growing season.

If anyone has any more tips, feel free to jump in. I don't grow up north, so I"m just giving general information that works for me.

Good luck!

I use MG potting soil wit a LOT of perlite for new cuttings. I have used the water method for rooting, and have also just jammed cuttings into a pot of soil with equal success. Just don't waterlogged potted cuttings.
