Boof Posted February 28, 2022 (edited) Hi All Very new to cactus keeping. Didn't know I was interested in them until some very generous members on here gave me some (thanks fullahs!). Two of them have something wrong with them; one of them likely fungus given how wet SEQ is right now. The issue with the other one has been going on for a little while, but I think looks worse in recent days. It looks like the cut is dying / turning "woody". The photo isn't great, but I'm referring to the yellow / light brown along the length of the left hand side. It is quite a wide band that the photo only shows a portion of. Hoping that the pup it's throwing isn't one last attempt at reproduction before it dies... After some management advice on how to rectify. Thanks B Edited February 28, 2022 by Boof Clarity Share this post Link to post Share on other sites
fyzygy Posted March 1, 2022 Not sure about the faded yellow section -- could just be from excessive sun exposure? The black spots I'd dust with cinnamon as a precaution against pathogens. The yellow/brown bits too, wouldn't hurt any, IMO.* Exposed wounds in plant tissue can potentially benefit from the application of cinnamon or cassia bark, either powdered or in aqueous solution, as an anti-fungal precaution. I've used it a lot, over more than 5 years, without any ill effects. Fungal infections are easier to prevent, than cure. * Not everyone on this forum shares my high opinion of Cassia spp. as an organic horticultural input. Hence my reluctance to respond to your post more promptly. But since no-one else has chipped in with any advice, I offer this in lieu. https://growplants.info/plant-care/cinnamon-for-plants/ https://luv2garden.com/cinnamon_fungicide.html https://www.sciencedirect.com/science/article/pii/S0304423818301316 https://treehozz.com/does-cinnamon-kill-fungus https://pubmed.ncbi.nlm.nih.gov/15607195/ On 28/02/2022 at 1:41 PM, Boof said: Very new to cactus keeping. 2 Share this post Link to post Share on other sites

fyzygy Posted March 2, 2022 If it's safe for germinating seeds, raising seedlings and rooting cuttings, then cinnamon probably won't harm an established plant. I hope it helps. Share this post Link to post Share on other sites
