Re: [SHADEGARDENS] Kerria japonica cuttings

John,
I would think Kerria japonica would root very easily, it tends to root on its
own when its floppy limbs are in contact with the ground for awhile.  I would
take cuttings in mid-June, the way I do with any deciduous shrub I want to get
started, and put them in sand and keep them moist.  In about 4-6 weeks they
should be rooted.  After this, I put my cuttings into a nursery area (has good
soil) and grow them on.  If you baby them for the rest of the growing season,
they should be ready to move to a final location the following year.  I have
gotten cuttings of hydrangeas, viburnums, roses, ancanthapanax, euonomous,
holly, etc. this way.  Since this is a really strange year, you might take the
cuttings earlier than mid-June.  You want to get the new growth before it
hardens completely.  Also, I do use a hormone powder on the nodes, and usually
strip the leaves from at least the last two nodes on a branch.
Hope this will be something you try.  It's so easy to get cuttings going of
SOME deciduous shrubs.  Let us know how it goes.
