Thanks for the replies.

Somebody mentioned a problem with a certain hormone causing too much
callus formation: I have found this to be the case with some other plants
and usually a lower concentration will reduce the problem. You can also
remove the callus if it gets to be a problem; it won't usually take the
root primordia with it, and is often helpful because it can inhibit the
new roots' growth. It was once thought that callusing is a necessary
prerequisite to rooting but it is a separate process that has nothing to
do with rooting. (What is the percentage of IBA (if that is the one) in
the product you are using? I like to use liquid form hormones because
they are easy to dilute and you don't have to buy three different ones for
different strengths (of course, there is a greater potential for waste
too...but you can use an eyedropper to mix small amounts. :)

thanks again,
