My croton has started to grow this long seed thingy (??) .. at least I think it is seeds.
How do I harvest (and WHEN do I know the seeds are mature enough to harvest) ??
Also at what temperatures/conditions would I germinate the seeds ??

I am trying to upload a few pictures, too

While you are at it ... can you tell me why my croton has started to grow yellow leaves (it used to put out new growth which was light green and which turned dark green, but now it is yellow and only very slowly it is turning, but more to a redish color). ??
I recently moved this one from a window to growlights. Can this have anything to do with it ? (I also started using a new fertilizer with higher levels of nitrate..)
