You will get many more plants if you take cuttings with a heel & no attached roots. Apply 0,8% IBA (rooting hormone) stick in well drained soil, bottom heat or a coldframe. rooting time 60-150 days & will take 1-2 years to produce a 1 gal plant.

Thanks, for the advise. I was hoping to shorten that 1-2 year period required when doing cuttings with a heel. That is why I wanted to try attached roots. If you think more would fail that way, then I will experiment with a few attached roots and do most of the others like your suggest.

Just found Purdue University Cooperative Extension Service posting on all the forms of Layering propagating.

Out of the processes they list for each type of layering, it seemed reasonable that air layering in the pot would be a most efficient way to propagate 100 new 'Golden Globes' from 10 of these potted shrubs.

I guess now all I need to determine is if the potted shrubs I purchase for the air layering technique have thick enough stems for me to make the air layering cut.

Georgez5il, from where do you purchase your often recommentded IBA rooting hormone? Do the Box stores sell it, or is it one of those products one only can get from a well stocked local nursery?

Hi! You can purchase 1/2 - 1 ft. natural roots online from the Arbor Day Foundation. Regular price is $5.50. Join (I think $15 annual fee) & get member price of $3.49.
