In case some poor soul stumbles on this instead of some of the other
fine reports on the web.
Further research (on the web) shows tomato cuttings root easily - with
tap water or weak rooting solution. Sounds like the rooting hormones
give you more roots but whether the difference is worth the trouble
appears to depend on your circumstances9 are you in a rush? not in a
rush, quality of tap water, etc.). Reports of using only tap water,
reported 14 days for good roots.
Roots developed in water, according to several reports, transplant into
soil very nicely. Some people report that its almost difficult to get
a cutting not to root! One can bury an unrooted cutting, in the right
circumstances, and it will still root nicely.

Here are two links that worked for me:

As you can probably see, I just searched the newsgroups via google for
"tomato cuttings" ...

Happy Gardening
