Hi folks.  At university, we got about 100% rooting with P. persica using mist beds.  I was hesitant to try 
rooting prunus without a mist bed, but Gianni inspired me to give a simpler method a try.  I used an 
alcohol/IBA dip and stuck the semi-hardwood cuttings in well-drained potting soil and bagged the whole 
arrangement with a large plastic bag (not clear- a white bag to reduce sun intensity and heat).  I put that 
contraption on a shady side of the yard and, like Gianni said, I misted it with a misting attachment on a hose 
periodically (continuous for 1st 24 hours, then every few days for the next few weeks).  I stuck 5 cuttings from 
a wild peach and 3 each from a Peento and an Indian Blood Cling.  I just transplanted the results:  2 wild 
peaches with >>>extensive<<< root systems (over 2 feet long and plentiful) and one IBC with a few roots, all 
less than 5 inches long.  One of the Peentos stayed leafy and green for months, but it was dead today.  

So the bag system can work, though no where nearly as well as a proper mist bed.  I don't know if the same 
procedure would work on P. tomentosa, the reference book I look at most often "Reference Manual of 
Woody Plant Propagation" by Dirr & Heuser recommends this... Softwood cuttings (though they say July- so 
depending on where you are this may be semi-hardwood); 8000 ppm IBA talc (good luck finding IBA talc at 
that concentration through normal channels) plus thiram in sand with mist (specifics on the mist aren't listed, 
but probably 5 second mistings every minute would work).  They got 100% rooting- 'bout like what we used to 
get with peach when we had a mist bed.  Del, if you really want to root a lot of cuttings, setting up a mist bed 
would be worth it.  If I remember right, the peach cuttings were done with much less IBA (2500 ppm), but I 
used a 5-second alcohol dip instead of talc, so the effective concentration may be essentially the same.  

Zone 7/ 8 and hopin' Winter and rain comes soon.
