Case Study: growing jujube on their own roots from green cuttings

The important details from the Original thread are reproduced here in case the thread or forum they were posted in disappears as things on the internet are prone to doing.

The author doesn’t say where he is located but he does mention -20F temperatures during the winter after taking his cuttings and his forum profile says he is in Zone 5.

7 inch fresh green cuttings were taken on June 5th 2018. The trees were 5 years old and had leafed out around May 1st, so the green wood had been growing for about 4 to 5 weeks. 4 green leaves were left on each cutting. On the bottom end of each cutting two inches of bark was scrapped off and dipped in powder rooting hormone. The bottom 3 inches of each cutting was burred in Miracle Gro Moisture Control Potting Mix and each cutting was covered tightly with a clear plastic cup to maintain high humidity. There were several cuttings in one large pot. The cuttings were watered every other day, “just water enough to keep the Miracle Gro moisture control potting mix moist so the plastic cups formed water droplets in side the cups”. The The cuttings were kept in partial shade. It took about 2.5 months for roots to develop. The author says that the potting mix he used made it easy to separate the cuttings once they were rooted.

The author showed pictures of his trees after 3 years and they seemed to be doing fine, but they are in pots. They may or may not do as well in the ground on their own roots.

Cultivars trialed: Li, Autumn Beauty, Orange Beauty, Shanxi Li, and Honey Jar.

I have tried many different ways to propagate Jujubes and find hardwood cuttings placed on a hotbed, under top mist the most successful.
