Ishmael Fleishman Posted January 17 I was wondering if anyone has had success with using Indole-3-butyric acid to get Cactus to pup? I bought some Indole-3-butyric acid rooting gel and sucked it up with a large syringe. I then injected selected spots on my Trichos. Anyone got experience?

Alchemica Posted January 18 I tend to hear of 6-benzylaminopurine being used for pupping which is quite a distinct compound (synthetic cytokinin with stimulatory effects on cell division) with a different mechanism to IBA That said, try it and see what happens. IBA has: - auxin-like effects such as root initiation, stem bending, and leaf epinasty - IBA-derived auxin has strong roles in various aspects of root development, including regulation of root apical meristem size, root hair elongation, lateral root development, and formation of adventitious roots. - IBA-derived auxin plays distinct roles in shoot development, with particular roles in cotyledon expansion and apical hook formation. Some studies indicate: - IBA application promotes elongation of stems in intact pea plants "IBA could act as an important source of auxin to boost stem elongation in intact plants" - In carrots it seems to cause longer plants "IBA significantly increased the overall plant length." 1 Share this post Link to post Share on other sites

I've tried a different hormone/product in the past, specifically formulated to promote pupping, and it did ... nada. (I can't remember the name, it comes in a godawful lanolin base). Pruning the tip is the only surefire method I know of to stimulate production of new pups. Slab grafting works too, on a smaller scale. Interested to hear how your experiment goes. 1 Share this post Link to post Share on other sites
Ishmael Fleishman Posted January 19 Found 1g | 6-Benzylaminopurine - 99% for $8.14. https://www.ebay.com.au/itm/334620358648 Must be pretty powerful stuff and expensive. Any thoughts on dosage? Do It inject the solution into cactus areolas? Share this post Link to post Share on other sites
thegreatartist Posted August 8 What happened to your cacti? Did they go bananas with roots everywhere or did they pup from the first injections? Sounds like a crazy idea but who knows. Share this post Link to post Share on other sites
Mr. Bowser Posted September 1 I found liquid kelp fertilizer as a foliar spray works well to encourage basal pupping, as well as enhanced growth rate overall. Share this post Link to post Share on other sites

I've been wondering about heavy metals in seaweed, some of the food-grade kelp is harvested in specific (ahem) "pristine" locations, and/or tested for traces of things like mercury.

Mr. Bowser Posted September 3 I spray at night but let me back up a second. The liquid kelp made the bridges pup basally. The other cactus had no basal pupping effect. Share this post Link to post Share on other sites
