Can anybody tell me what could be the problem?

. Hi, Lintama, I grow lots of Cordyline australis, if you get this problem (a type of rust) spray with Dithane 924 and this will clear it up. Professional growers of cordylines use this as a routine spray to keep the plants green and healthy. Just a little tip when using Dithane powder (which is notoriously difficult to mix ) use a coffee jar with an inch of water in it , tip the powder in, put the top on and then shake vigorously to mix, then pour into sprayer.
best of luck lannerman.
