"Hi Maree, I'm quite confident that there is absolutely nothing wrong with your cycas. It is quite common for them to skip a season without flushing, sometimes stress related, but I doubt this is the cause. With cycas you can almost always tell if something is wrong by looking at the colour of the leaves - like if there was a mineral shortage they would turn yellowish or show signs of burns at the tips of the leaves the most common problem and cause of death with them is root-rot, this can also be picked up by looking at the leaves - the base of the leaves becomes a darkish rot-like brown, which progresses towards the tip of the leaves as the root rot becomes worse and goes untreated. Just as a side note - you won't be able to see changes in the current set of leave if you try and correct the condition by adding compost or whatever, it will only show in the new set.
But with yours, I suspect the answer might relate to the age of your plant - as the plant gets older the flush gets larger and preparing for the larger flush takes more time and nutrients. So I think it would be safe to say that you can expect a nice large one before December this year. You can also try feeding it with Seagrow or just a healthy dose of compost from your heap and watch it prosper."
And now, here's the wonderful proof of this!
I am absolutely thrilled that he is OK! I've been spending the winter worrying about him and talking to him, and at the end of winter I did give him a good dose of compost.
So, a big thank you "A", for setting my mind at ease and also for the wonderful information you imparted, very grateful for that!
