Christopher, what I have observed and read carefully what you are reporting that there is a difference, have you thought why this is so. C obliqua, the species took offense of the weather conditions, the hybrids, did not. I think you can figure out why. How hot is your highs, and how low are the lows at night this time of the year, I realize I am not supposed to know anything because I live in Calif. and have been told so many times but C obliqua is a very old name, and common Jade' was on earth long before we collected plants. I hope you will take the time to respond to my questions it is for my own knowledge. Thank you, Norma

Hey, Christopher!
'Crosby's' is one of the best-rooting Jades, in my experience.
It's one of those varieties that you can just lay on top of soil and
a ton of roots will shoot from the nodes in no time at all.

I've noticed, however, that varieties with variegated or pale leaves
are more difficult to root...perhaps because of less chlorophyll?
This includes obliqua and 'Hummel's Sunset.' If they aren't pampered,
I find that they shrivel up before the rooting can begin.

Hello Christopher,
I noticed the same thing. I have had quite a hard time trying to get 3 cuttings of Mike's variegated jade to root for me. I want to say it took almost 2 months for me to get 2 of them to root for me. I still have one that has not rooted and a couple leaves that have not rooted for me. My Hummel's cutting that I recieved from Norma rooted fast though. I also have not had a hard time rooting cuttings and leaves. I ordered a Hummel's from Ebay and lost the whole plant with the exceptions of the tips of the plant. I put them in perlite with some leaves off of Norma's cuttings and put them into high light and NO WATER. That was how Norma had told me to root the cuttings. She had said that you could root cuttings simply by putting them into an empty pot, no soil at all. I had cut the cutting she sent me into two pieces. The smaller cutting I put into an empty pot. The larger cutting I planted in a soil mix. The smaller cutting rooted in about 4-6 weeks. Maybe these results are not typical but it worked well for me!

Norma:

Temps here had been in 80s to low 90s days, down to 60s and 70s at night. Overall an exceptionally warm summer here. Now of course as late August is here it should be cooling off. I just think C. obliqua may have somewhat different requirements. Mike's cuttings did not give me any problems at all, so I don't think that variegation itself is the issue.

I have a cutting of Hummel sunset right now that I'm trying to root...I know that this is the worst time of year for me to root this cutting... I have it in DRY Gritty mix since July 4th...as of today(7 weeks later) NOT one single root has grown on the cutting. The plant in general looks very good (no rot) lost a few leaves but other than that looks great...I'm hoping that it will put out some roots in about a month or two? Wish me luck!

Christopher,
Mike's cuttings had a great deal of green to them, so I wouldn't foresee problems with those.
Cuttings with at least half-variegation (like C. o. obliqua) might prove more difficult.

Nancy, good luck!
Almost there! Just another month....
