Great for orchids and other epiphytes though which do not have fine root structure.

Granlular fertilizer too much too soon.. perhaps use a weak water soluble fertilizer while the plants are that small and then introduce granlulars when they are much larger when you repot as they get larger.

For me, ensete's are tender when they were young but as they become larger they are robust .

I would also change the soilless mix to a peat moss perlite based medium to give those roots something to grow into. Your current medium will not allow this for it is too dense and large.

A couple of these pics can give you an idea of the soilless mix.
Double click on the photo if you wish to see more photos.
It will take you to my public Flickr account where you can see more mixs.



There are some good recipes for soilless mixs on youtube which can help.
