Apr 26, Rooting evergreen azalea stem cuttings is not difficult if you use semi-hardened cuttings. That means the wood you take should be somewhere between soft and brittle.
It should bend, but not too easily. Dip the tips of your cuttings into the rooting hormone, and stick the cuttings into your potting mix. You can put them pretty close to each other, because when their roots begin to grow you’ll be moving them out of this container anyway. Rooting your own azaleas is practically free, and you propagate many new plants from a single azalea bush.
Even if you have just a 6-inch pot, you can have as many as 20 to 30 cuttings taking root.
The best time to take your cuttings is in the latter part of May or early June. Nov 28, To keep the cutting from drying out, you need to create percent humidity. Do this by enclosing the pot in a clear plastic bag or placing.
Wound the cutting with a cut on each side, about 1/2" to l", just deep enough to cut through the bark. Dipping the cutting in a rooting hormone containing indolebutyric acid will make rooting easier. The exact formula depends on the hardness of the cutting and the difficulty in rooting the cultivar you are tying to propagate.
