Hi CK, thanks for the response (you too Charlie!), this is a photo of the container.

It has no holes in the bottom and sits in the larger plastic wicker one. There is only a surface layer of gravel on the top, and I have given it an aquatic plant feed. I have a feeling it’s missing a nutrient of something, I did think about giving it a dose of lucozade! (Other well known brands are also available!). As I mentioned previously it is planted in Westland aquatic compost.

Beats me, when I had one years ago it just grew. But then I did have Koi in the pond which gave it extra nutrients. Sorry I cant help.

Thanks ck, I’ll bide my time and see what happens
I’ve just taken this photo and there are signs of green appearing on the leaves, so maybe I’m just being too impatient, I thought the leaves would initially appear more green than yellow!

A week on and some sunshine, and ribs of green are starting to appear, plus some colouration on the stems. Hopefully my initial thoughts were unfounded
