Note: Some plants are patented. Please check to see that the variety of plant you are taking cuttings from is not covered by these patents. This information can be obtained from USPTO (United States Patent and Trademark Office)
If it is a newer heuchera introduction, it is probably patented. Some of these varieties will hit the patent websites in a matter of a few weeks or can take a couple of years.
1. Cuttings can be taken any time of year, however they do better in the Spring when it is cooler. This gives both the mother plant and the new baby plant time to recover and become established before Winter.
2. When removing the leaf cuttings from the mother plant, make sure you find the stem/petiole of the heuchera. It is critical to include this part in your cutting.
3. Remove leaf cuttings with a sharp knife, ensuring part of the stem is included in the cuttings.
4. Dip leaf cutting into a rooting hormone, tapping off any excess.
5. Plant leaf cuttings into a moistened mix of 50/50 perlite and peat moss. ‘Tent’ a clear plastic bag over the cutting, using wooden skewers to keep the plastic off the leaf cutting. Place pot and bag in a shaded area, ensuring cutting receives light, but not direct sunlight.
6. Check cuttings daily to make sure they do not dry out or mold and stay moist. In about 6-8 weeks, roots should start to form. A gentle tug on the cuttings will let you know when roots have started to form.
7. To ensure there are enough roots on the cuttings, wait several weeks after roots have started to form prior to starting process for hardening off cuttings. When completely hardened off, plant out in garden.
I had some discussions with Terra Nova Nurseries regarding this topic. They informed me that the new plants from this type of propagation will not grow very large as this type of propagation does not include any leaf buds. This makes these new smaller plants ideal for containers or to tuck into a small spot in your garden.
Good for cut flowers
