Re: Oak Leaf Hydrangea

Softwood cuttings taken in July will root with bottom heat.  Dirr says they
need relatively high IBA (0.8%), which may be why my success was limited. 
I did get a couple to root with only Rootone, however and no bottom heat;
just the heat of our normal July.   So, it is possible.  I struck the
cuttings and left the pots outside in the shade in a flat covered with a
clear plastic top to keep in the humidity.  If you do encase them in
plastic of any kind, make sure *no* sun hits them or they will cook.  This
was a few years ago and I seem to remember that I got like four or so to
root, but lost two over the first winter although they were in my cold
pseudo greenhouse for the duration.  Seems to me that most Hydrangeas root
fairly readily, but getting them to grow on can be a bit tricky - may just
have been my, ahem,  technique :-)

BTW, these plants sucker and it is possible to dig up the suckers in very
early spring (like early March for me) and get them to grow on.  I've given
some to people at that time of year and they have planted them and had them
grow fine for them.  

One of my very favorite plants...now blooming for all their worth.
