jc360 Posted February 1, 2009 Report Share Posted February 1, 2009 i have a Cleistocactus straussi cacti that has developed a case of the shrinks about 20 cms from the top. it has also changed colour from green to yellow in the most infected area and has also gone brown in the most shrunk section. the top of the cacti has gone from nice and straight to a right angle in a week and i suspect fungi, or rot. any help would be great as to naming this problem and a cure to go with it would be fantastic!!!

David R Posted February 1, 2009 Report Share Posted February 1, 2009 Is it inside or outside? The skinny weak growth sounds like etiolation. http://cacti.co.nz/cultivation.html Quote Link to comment Share on other sites More sharing options...
jc360 Posted February 1, 2009 Author Report Share Posted February 1, 2009 thanks for that great web page David, yeah the plant is outside and i actually think it could be sun burn??? just had a quick look at that page going back there now, cheers.

David R Posted February 1, 2009 Report Share Posted February 1, 2009 Could well be a rot from damage, or sunburn if it has recently been moved from inside to out, or turned. Best bet at this time of year would be to cut and re-establish the tip, depending on how big it is. Quote Link to comment Share on other sites More sharing options...
jc360 Posted February 1, 2009 Author Report Share Posted February 1, 2009 yeah it was recently turned about 3 weeks ago. So is it rot??? the infected area is very tuff, not juicy like i would expect from rot. the plant is about 6foot and only the top 30 centimeters is currently affected.

David R Posted February 3, 2009 Report Share Posted February 3, 2009 Looks like sunburn, that species is notoriously soft and doesn't develop much of a woody skeleton. Cut the tip off, take it as big as you can with out getting into damaged flesh, give it about 3 weeks to dry off then plant it in a pot.

jc360 Posted February 3, 2009 Author Report Share Posted February 3, 2009 yeah cheers David. Was going to divide up the stem of the plant into six 30cm sections to make some new plants, does that sound like a plan that could work??? Quote Link to comment Share on other sites More sharing options...
David R Posted February 3, 2009 Report Share Posted February 3, 2009 Yeah it might do, it will with some species. Just make sure you keep the direction on the logs so you know which end to stick in the ground! :lol: Quote Link to comment Share on other sites More sharing options...
jc360 Posted February 3, 2009 Author Report Share Posted February 3, 2009 yeah true that Stella, and one suffers from the other. Quote Link to comment Share on other sites More sharing options...
