I have a Penstimon - Husker Red- and am looking for advice on how to propagate this plant.
Thanks for any advice.
Can take cuttings of firm new growth... apply 0.1% IBA (Rooting hormone) Stick in well drained soil & mist taking 15-30 days to root.
How long should the cutting be and does it have to be cut at the base of the plant or just any of the new growth stems?
I have a small jar of rooting hormone I purchased at Lowes so should I just dip the end of the cutting in the horomone?
Keep in the shade or direct sunlight?
Thanks for the help.
You can root these cuttings in water very easily. I have seen many of these done. If you look at the bottom of the stems, you will notice they have little white bumps that will make roots quickly...at least the one I bought today has them.
You can also collect the seed and winter sow them. They reseed readily, at least mine does.
