Glass Roots Posted August 30, 2013 Just noticed a couple of these black spots on my bridge but I'm not sure if it's rot or what. It's only showed up on the new pups. What is it? Should I cut it out, or maybe remove the pups? Sorry my camera couldn't take clearer pictures. 1 Share this post Link to post Share on other sites
Optimystic Posted August 30, 2013 as others will say im sure, most of the time they'll just dry up... bridgesiis seem more prone to black rotted spots than other trichos... usually a response to a little too much water, humidity or over feeding I've had them a couple times on a penis plant... both times the pup was half rotted and had black ooze and so in those cases I just cut them off, but never seemed to pass to the main penis but in cases where they look as that, just watch them,,, they may start drying up quick.. just don't water them keep away from moisture for a bit..with those simple steps, its very likely to just stop and callous over...

Glass Roots Posted September 5, 2013 Update: The black spots are growing in size and it seems there are more smaller dots showing up on the pups. Also looks like a black spot is showing up on the main stock right at where the pups are. Share this post Link to post Share on other sites
Optimystic Posted September 5, 2013 (edited) your first pics appear calloused in the middle so my first assumption was the typical rot spots and they dry up just like those in the center.. I wouldn't rule out some type of bug bites... and if thats the case well eliminating those and sulfur would help but if its a genuine infection then you'd want to cut right away.. since there is spreading then fast action would be called for... same rules, clean blade with alcohol and dry before every swipe til theres no discoloration... the only exception being near calloused skin, the underlying tissue is usually discolored... I'd personally cut the pup off and a good size chunk beyond the spot and be worry free someone else may want to chime in as theres still the possiblity of other causes... Definitely check your soil, if it hasn't dried out then it could be soil related, particularly with bridgesii but also with any plant which hasn't had time to establish (I think for some that means an entire season but thats must my O) ... if thats the case I would uproot so the roots can dry out... another thing about bridgesiis, is they repond really ugly like to too much nutes especially nitrogen... if the soil is truly bone dry then i'd be concerned about an infection in which case, time could be working against you... maybe poke your finger in as deep as you can and if theres still moisture.... I had a bridgesii that responded with lots of spots the first season... and the soil was too moist.. one I saved but the other did just fine in the 2nd season once established.. one spot growing, not so much an issue, but multiple new spots plus oozing = yikes! any new pics?

PD. Posted September 10, 2013 usually a response to a little too much water, humidity or over feeding Dont cut into it, leave it alone. If its into the core and its a small plant then turf it. If its a big plant then then let it dry out and lay off the ferts. Bridgies get spots all the time and generally heal up as soon as you stop worrying about them 1 Share this post Link to post Share on other sites
Glass Roots Posted September 10, 2013 I'll throw up some new pic's tomorrow when I get a chance. It's about 60cm, and yeah I haven't watered/fertilized it since the spots showed up. Share this post Link to post Share on other sites
Evil Genius Posted September 10, 2013 (edited) Hi Glass Roots, pretty sure thats nothing to worry about. Edited September 10, 2013 by Evil Genius Share this post Link to post Share on other sites
Glass Roots Posted September 10, 2013 You can see that newer small dots are starting to pop up It's now spread to the main trunk, right underneath the right pup. Share this post Link to post Share on other sites

AndyAmine. Posted September 10, 2013 (edited) If you are worried hit it up with some fungicide, its about all you can do. Lime/sulfur is good but Mancozeb is better and has a short withholding period. But really it doesn't look too bad and this year seems to be a big one for spots. I know of quite a few people saying their collections are showing higher levels of fungal/bacterial issues than usual.I blame it on chemtrails.. Edited September 10, 2013 by AndyAmine.
