This weekend I picked up some cuttings of a red flowering crape myrtle to propagate. I took 6 inch hardwood cuttings that were just beginning to leaf out. Since I didn’t have time to treat them right away I left them in a jar of water overnight to stay moist and treated them with rooting hormone the next day.
Here’s the crape myrtle propagation method step by step. (Of course it can be used for many other plants as well.)
Crape Myrtle Propagation
1. Prepare your potting medium. In this case I used sand but a 50/50 mix of sand and peat would work fine. Vermiculite is another good medium to use.
2.Take the cut end of the crape myrtle and dip it into the rooting hormone. I usually just dump a little hormone into a cup then dab the end of the cutting into it. Don’t stick your cutting into your jar of hormone or you may contaminate it with any diseases that the cutting may have.
4. This step is the hardest…wait. Wait for the cutting to hold to the potting medium after a slight tug. If there is resistance (it usually means there are roots) I usually add enough water to make the sand soft enough to easily pull the cutting out of the medium. The other option is to remove all the plants at the same time and gently separate them. Only do this if you are sure of success. You could damage roots in the process of taking them out to simply check on them. If your pot has holes in it and roots start emerging from the holes you are in great shape to pot up your crape myrtle cuttings!
5. The best step…enjoy the new plants! In about 6 weeks (or maybe less) the new little crape myrtles will be all set to grow in the garden.
In a few years your crape myrtles will be flowering like this!
