Nice story, do you plan to keep it as bonsai (pruning roots in the future)?
So you're saying that too big pot was holding it's growth so significantly ? Are Lytos more vulnerable to this factor than other palms ? I was always thinking -bigger pot - bigger growth overally. That's something really surprising.
(2) the drainage not optimal.
If the drainage had been optimal I guess the roots had been looking better. But if the pot had been a small 8x9cm pot even a not so good drainage would not have caused such problem.
As my other Lyto weddells — except those twins I am trimming as bonsai for my desktop — are all growing too fast for placing them on the window sills I try to keep that palm N°1308 as small as possible, but my success does not last longer as it seems ….
Interesting post, and a lovely palm!
