Buddleias are incredibly easy to start from cuttings but they cannot be too
large or they become hard to root in my experience. No more than 5 or 6 inches
for cuttings, remove all the lower leaves and stick them in the soil. They
will root with 1 or 2 nodes but 2 nodes will root alot faster. No rooting
hormome is necessary. Its better to find a stem with no flower on it, or just
pinch it off. As for deadheading, take the branch back as far as you want.
You could graft them if you want, but they grow so fast that this isnt
necessary, and takes more skill than taking cuttings. This year I took
cuttings from my 'nanho alba' about mid june, the cuttings were about 3 inches
long. It is mid august and I now have finished one gallon plants that are
almost 24 inches tall and loaded with flower buds. Why these arent dirt cheap
at the nurseries is beyond me because of thier incredibly quick finishing time.
