Top heavy due to big fat and heavy leaves.
Filling your pot to the brim will provide all the support she needs, so no need for the stick/wire.
In time, the buried portion of stem will grow roots. Having a full pot will also provide more room in general for root growth. The soil will sink down in time, meaning watering and feeding will always be easy.
Just remember, more roots = more plant!
Hope this helps,...........
