That's amazing! Do you have a skylight? It must be a big pot.

How long have you had it?

She is about 8 years old getting 'children ' every year and is flowering every november december, the pot is 55cm diameter and cannot be changed the plat is too huge. It has several windows around but no direct sunlight. About every 2 weeks 2 liter water and every spring dried cow-manure. And of course every day live classical flute music from my wife.

I have one in the garden that is getting that long. I was hoping originally that it would grow more bushy. But it goes up and than falls over. So most of it is along the ground. No new shoots coming from it. I assume yours is supported to keep it upright.

Yes, you have to support a dieffenbachia, and prevent it from direct sunshine, but it needs enough light from all directions.

Diefs don't mind some sun, but acclimation is tricky after a plant has been inside for months, or longer. That pot had about 8 individuals planted together when I got it.

Tropic, as far as I've seen, Dief stems never lignify, so they never get strong enough to support a really tall specimen. Is the fallen stem in contact with the soil? It should take root all along the length and form a "raft." If you get a chance to share a pic, I'd love to see your plant.
