Night blooming jasmine?

How to grow from clippings? Can you and are the clippings best off in water or soil to root. Any advise would be greatly appreciated.





Also, how long from clipping will it take before I can transplant into pot then outside??

Night blooming jasmine?
Hey! Night Blooming Jasmine aka Night Jessamine.


'Botanical name': Cestrum nocturnum.


I have a shrub in a #15 sized (decorative) container. 10 years ago, when I lived in San Francisco - where they are 'rather common' and can grow into 2 storey specimens that fill the late August air with their pungent/sweet aroma - I started several new plants from semi-hard wood cuttings (2nd year growth which is partially woody and partially green) in the soil near the 'mother plant' in the fall. I took 8-10" cuttings, reduced the leaves by 90% and left at least 4-5 'nodes' - removed the lower leaves - and merely stuck them into the ground about 5". Winters in SF are generally cool and wet. By spring the cuttings had rooted and I was able to transplant them.


I moved to north to Sonoma County where we often get freezing night temps in the winter. Although the plant froze to the soil surface (in a container) it has sprouted and the plant is about 4' tall and now beginning to set bud. I used a 20-20-20 fert. and am now switching to 0-10-10 for abundant flowers.


I would say that any technique resembling the one mentioned above would do the trick. You could, if it is planted in the ground, bend a branch down to soil level, remove a section of leaves and bury a portion of it (using something for weight like a rock) in the soil. Roots will sprout from the old leaf scars after a few months (maximum.) You can then dig up the new start after cutting it from the original stem.


As far as starting them in water...I'd use the same technique as stated for starting semi-hard wood - being sure to reduce the leaves considerably. How long by water? I don't know.


(FYI: C. nocturnum is in the Solanaceae Family - aka the Potato family - they bear flowers that are nearly always star or saucer shaped and 5 petaled: fruits are berries or capsules. Plants are frequently rank smelling or even poisonous, but many are important food crops -- eggplant, pepper, potato, tomato. Others are garden annuals, perennials, shrubs or vines -- Browallia, Cestrum, Nicotiania and Petunia, to name a few...)


I hope this answers all your questions re: Night Blooming Jessamine. It is 'very easy' to propagate...


Happy Gardening!
Reply:I have been successful with clippings from a rubber tree. What I did was cut a slit just above a branch. You spread the wound slightly, sprinkle it with Rootone, and wrap a cloth filled with potting soil around the branch. Then wrap plastic wrap around that. Keep the area moist.





Within a month, you should have a root system going in the dirt. That's the time to finish the incision and put it in a pot. I'd baby it through the winter indoors and wait until spring to put it out.
