Re: Cultivation of Taccarum

Dear Hannon,
I keep all tubers dry when they're dormant, even I dont water them until the new bud grows enough large to break.
As for the soil - should the tubers stay in the old soil during the dormancy or should I change it as the roots wither
or when it starts to grow again?
In all the methods there are good and bad things.
1. Leaving the tuber in the old soil means leaving it with all pests and the soil itself often remains wet too long at the bottom of the pot what may cause rotting. Next season the tuber can start to grow too early and repotting it while producing new roots may be fatal.
2. Repotting it shortly after the leaves wither - the new soil left dry for a few months loses its moisture and structure, it turns into dust and sand.
So when is the best time to change soil in pots?

Agreed that keeping it in its pot when dormant is a good idea, as with all geophytes. But Taccarum should be kept DRY when dormant. This is true for probably most but not all tuberous aroids.

Your problem is taking it out of the soil, it needs to be kept in the pot and moist at all times, also needs to be outside not in a window.

I've had Taccarum weddellianum since 2005, every year it produces a leaf and usually a "baby" tuber.
But... it doesn't grow in size almost at all, although the tuber very slowly increases, the leaf is 20-30 cm tall every year.
I use regular pot soil, and the plant is fertilized with natural biohumus.
It grows in a southern window.
When it's dormant I store it without soil in the normal room temperature.
What do I do wrong? What should I do to make it grow larger?
Here are photos of my plant:
