A Nice Rooting Environment for Large Cuttings

Using an aquarium air bubbler is a fairly inexpensive way to speed up the rooting of larger cuttings.

Hello I am particularly interested because there seems a few advantages that I can forsee. First one can see easily that the stem cutting has generated a root system and then it can be potted in its soil. However, would you suggest it for a particular group of plants.( i.i. do you have tried it with rhododendrons or rose bushes or dahlia stem cuttings?). Thanks. P.S. propagation by cuttings is such a pleasurable endeavor that I don't restrict it for any moment of the year. Now its spring and some of the house plants could be propagated your way. Thank You!

I always use a bubbler to root the larger cuttings like brugmansia because first there is a lot of oxygen in the water and I believe it's easier for the cuttings to take up water easier than in a moist substrate thus you get way less vascular collapse. Also with the constant movement and aeration of the water there is a huge reduction in stagnation.

The picture is of a brugmansia cutting I received that started producing pre-roots in less than 24 hours sitting in the bubbler.

Aha, another fun project to show my propagation classes.

The root structure that Gordon shows in his photo after only 20 days and Anne's picture of the overnight nubbies are pretty remarkable.
