Post Cibotium (regale) problems
My once Cibotium regale-sporelings that I received so graciously from Steve (some 12 years ago) are now quite mature plants. I do experience some problems lately in that new fronds are produced fewer and fewer -and when they do come out they are so much shorter/ smaller than they used to be..

I'm getting a bit worried..it does look somewhat pot bound. Could it be that they are too wet/ lacking nutrients (because of the old compost they're in/ almost never giving them a feed)??

Would it benefit from some new soil? The soil that I used 12 years ago is referred to as 'Anthurium-soil' in our garden centres over here..

I would send some pictures but I'm experiencing some problems with that..

Any help very much appreciated!

We all miss Steve.

He covered this subject in some detail here.

In summary - plant into a tub with ericaceous, soil free compost 'opened up' with more bark.

Chad.

ps. He also warned me they like to never dry out, but don't like standing in water at all!

Thanks very much for your help Chad (also in providing me with the link to the Cibotium article - it really does answer a lot of my questions)...such a (humorous) authority, Steve..

One final question though: I have read that it really dislikes root disturbance - but is this only at the juvenile stage? My plant has a pretty 'matted' root ball right now - and I don't know if I can reduce this a bit before putting it into its new soil and tub...

I was hoping someone with more experience would answer; I can only pass on Steve's advice to me.

That was to leave the root ball untouched. He was very scathing when I added perlite to the potting mix, pointing out that Cibotium 'eat' the compost. If all the potting medium is organic it is replaced by roots almost entirely. Not so easy to do round perlite!

Chad.

You cant leave the rootball untouched forever if you are not going to forever go up to a larger pot. Tree ferns like most all plants ( I wonder about Bismarkia palms),don't mind a root pruning and then fresh soil pressed in all around.

I have many Cibotium regale seedlings. The reduced fronds is signal to change the soil. I repotted my largest Cibotiums (regale, barometz, glaucum) a month ago, and I removed almost all the old soil by slightly hitting the rootball with my hand. All the Cibotiums seems doesn't care, all of them are healthy and the fronds didn't suffer. Any Cyathea would be dead after such experiment, but not Cibotiums. It is less risky just to cut some parts of rootball by knife and fill the empty space with new soil.

It might actually be a good way to have two Cibotiums. Just slice it in two..plant the two haves. You probably have various new fiddleheads around the main one right? Like a clumping fern. Study it first. :wink:

Thanks Navkratis...I have done it according to Steve Pope's and Chad's instructions..if that won't do the trick I might consider to be somewhat more brutal..
