2XB Posted March 25, 2015 (edited) Hi all; As we all gather here under the pretense of a corroboree I'd like to acknowledge the original owners of this land, that the world calls Australia, as its' aboriginal people. I hope we can all reflect, and support the australian Aboriginal people in anyway we can, as equal rights in this country are up to shit.... moving on..... Many of my cactus have been slain by extreme temps and high humidity here in SeQld... Its sad but i guess thats the way it is if you wanna grow something that wasnt meant to!! So yes many dead, but this a beloved seed grown Pilosocereus glaucochrous is still alive but with a large wound.... I am very fond of this plant.... my question is, do I leave this and see how it pans out, cut below and above the rot, hopefully getting new growth from the rooted section, and rooting the top half??? It appears very strong still, but it has been like this for 3/4 weeks, not getting worse, but i think the rot may travel up the vascular core with out visual evidence...... educated tipz welcomed! :-) Edited March 25, 2015 by doublebenno Share this post Link to post Share on other sites

quarterflesh Posted March 25, 2015 Cut it bro. It looks way top heavy anyway's. Share this post Link to post Share on other sites
2XB Posted March 25, 2015 (edited) Even though it lloks top heavy the trunk is almost like wood. Ie. Really rigid... Also it isnt soft when i push on it. It feels normal. anyway I am leaning to cutting, am looking for some hope I guess..... I would be shattered to find the inwards perfectly fine.. even more so to have no cactus left though....

Evil Genius Posted March 25, 2015 Could be benign black rot but with infections that big, it´s kinda hard to say. Zelly would probably leave it like it as and in most cases, that attempt is the right one. So yeah, I see similarities to black rot but it could also be something that will kill the plant. Really hard to say here. Share this post Link to post Share on other sites
gtarman Posted March 25, 2015 I'm gonna throw my vote in for cut it...that rotted section is not good news for the rest of the plant IMO. But then I guess it just stands a chance of happening again if conditions don't improve for it....is there any chance of giving it a rain roof like the cacti house at the bot. gardens?

Philocacti Posted March 25, 2015 (edited) I had a similar rot hit this seedling and I didn't do a thing and now it started growing again. .... And the infected part left this scab. Edited March 25, 2015 by Philocacti Share this post Link to post Share on other sites
zelly Posted March 25, 2015 If the black rot portion completely encircles the plant your only recourse is to cut it above the black rot area & re-pot & wait for new roots. Put it in the shade while it grows new roots if thats the case. It could 'survive' as it is (if the blackness completely encircles the plant), but its days are numbered. Think in terms of xylem & phloem, a plant requires both systems operational for healthy growth. 2 Share this post Link to post Share on other sites
2XB Posted March 25, 2015 yep, it completely encircles the plant :-( Thanks for everyones input, I will cut this arvo i think............... will post the results for interests sake.... Share this post Link to post Share on other sites
Halcyon Daze Posted March 25, 2015 Cut it at least 5cm above the rot. If you're lucky the stump may re-sprout. 2 Share this post Link to post Share on other sites
2XB Posted March 25, 2015 I planned on cutting closer to the rot, and then trimming until no sign of rot, cleaning my knife each cut..... would u advise against this tactic Halcyon Daze??? I do hope for the base to continue :-) Share this post Link to post Share on other sites
hostilis Posted March 25, 2015 If you do that make sure to sterilize the blade in between the cuts so you don't just spread the bacteria or fungi further. That's my advice. 1 Share this post Link to post Share on other sites
2XB Posted March 26, 2015 If you do that make sure to sterilize the blade in between the cuts so you don't just spread the bacteria or fungi further. That's my advice. Thanks man, I usually clean the blade with metholated spirits or something then a hit with a spirit lamp, would this suffice, in your opinion? Share this post Link to post Share on other sites
hostilis Posted March 26, 2015 That would work fine. Share this post Link to post Share on other sites
