I've never heard of crapes being propagated by root cuttings, so I can't help you with that one. But stem cuttings shouldn't be too difficult for you. There are many ways to do this successfully. I'll explain it simply, but you should do some reading to get more background. Others will have their favorite method, too. Take the cuttings from the newest growth, remove any flowers and/or seed pods. Take the cuttings with clean, sharp by-pass pruners (scissors action) so that the cuts are not smashed. They shouldn't be more than 6 inches long. Remove about 3/4 of the leaves (from the bottom of the cuttings) and stick into a very coarse, fast draining peat based potting medium with extra perlite added for porosity. You can use anything that allows you to insert the cuttings at least two inches deep, but don't use a container that is overly huge or one that does not drain. I typically use a plastic flat like the ones that bedding plant cell packs are carried in, or even into cell packs. Keep the cuttings moist, located in a shady location outside. They won't like the dry air inside. Do NOT keep checking your cuttings as you will destroy any fragile new roots that may be forming. I wouldn't touch them for about a month. If you feel resistance when you tug very gently after that amount of time, your cuttings have rooted. Leave them alone for several more weeks so that a proper root system can be developed, and then you can repot into slightly larger containers.

summerstar, this is a good place to put my post about my RED crepe myrtle. A girl down the street gave me a little cutting with roots off of hers. I babied it till it got to be about four feet tall, really healthy. My husband said it was too close to the flowering cherry tree, so I moved it,----and killed it.!!! So we went to PA. for a day, and I found one which said,"siren red". I bought it, planted it, waited patiently for blooms, and it bloomed profuselly,------Pink!!! Well guess what? A lot of little red ones came up where the red one was planted origionally. What to do with this PINK crepe myrtle, with almost a postage stamp yard? Maybe you should try root cuttings. :) Arum

Planting seeds from a dwarf cultivar may not (is unlikely to) produce offspring of similar size or even color. Your seed grown plants are likely to attain a variety of sizes and bloom various colors. In other words, you won't get consistent or dependable traits. If you really want to grow them from seeds, that's cool. I just want to make sure you know what to expect. If you are wanting plants similar to your original plant, you should definitely consider growing new plants from cuttings.

I, too, have read the thing about planting several cuttings together, but I don't buy into that thought because that just results in multiple plants that APPEAR to be one plant. I currently have 4 adult plants, and all of them have multiple trunks. Now, these adults' multiple trunks all start ABOVE the ground. In other words, you see one trunk coming out of the ground, and all the other trunks split off that trunk, which is what I like seeing. I want the same thing on these new babies. As far as your cutting goes, that's kind of what I wonder if I need to do. I mean, shoots typically sprout when you cut somewhere above the base, which is what basically happened to yours when that branch broke off. This is why I wonder if I should top mine. But, I am scared to do that because I don't want to cut the main stem for fear of it then causing the plant to split into multiple trunks at that point, which might be too high up. I'd really prefer if the splits occur down low, just above the ground, you know what I mean?
