No Roots

I’ve been growing both indoors and outside for three years and have never had an issue with clones until now. I take cuttings and place them in bottles of spring water until roots appear. To date I’ve had about a 50% success rate using this method. Currently, I have several Mazar-I-Sharif cuttings that have been showing the prerequisite white nodules on the stems for over two months without so much as a single root. In fact, most of the cutting stems are completely coated with nodules. Nothing has changed with regards to my grow environment (lighting, temp, etc.). Is there something I can do to encourage root formation? Thanks for the help.

Do you still have the plant to take new cuttings? wouldnt hurt to take some more with diff method.
In my opinion you should learn other techniques that encourage more roots in a quicker period of time with a higher % of surviving.
I like using the growdan gro-smart tray it sits on a regular 10inch by 20 inch tray that has a dome on top with a couple vents for lowering/raising humidity.
do you top off your water or change the water after a while? i try to change the water every few days or add to it.

Thanks for the response. I can no longer take cuttings as the plant is now in flower. Yes, I change water (new bottles) every three days. I appreciate your suggestion about alternate methods and clearly I need to move in that direction, however, my immediate concern is to save what I have, which equates to 13 plants. At this point, will the nodules root out if I plant the stalks in potting medium, perhaps using CloneX?

Try a rooting hormone. There’s a ton of them. Back in the early days of cloning, we used “Root Tone”, I think they still make it, but there may be better stuff now.

you can take cuttings from flowering plants, its just bloody difficult. how far in to flowering are they?

its not that dificult, the sucsess rate is lower

I'd change your method, because 50% is a poor success rate.
If you are worried then just pop 5 or 6 in a propagator using a different method.

I'm playing with an aeroponics cloner at the moment , bit my usual method is a seed tray filled with perlite alsat in an inch of water, of try root riot cubes or literally any method.

Not sure how much oxygen your getting in a bottle of water..

My first guess is that the cuttings are getting too much light & they're photosynthesizing instead of rooting.

Good luck

I often just use the passive water with clones and get close to 100% rooting rate.

When I had fails, it was almost always from too much light.
These days I aim for like 50ppfd for 24/7
