Rooting cuttings in plain water?

[JerryHaskins]

As I mentioned earlier, I have started rooting cuttings in 2-liter Pepsi bottles. It works great, but you have to remove the cuttings and re-pot them while the roots will come out through the small opening in the top of the bottle. Alternatively, you can just cut the plastic bottle opening with scissors and extract the newly rooted plant.

Attached are photos of 6 New Gold Lantanas I rooted this way, and have re-potted into 1-gallon pots.

I am trying to root some Shishi camellia cuttings but it's not doing much.

I did root a coleus cutting for my wife, and it is doing great---almost ready to re-pot.
