The Fittonia variety are a generally easy to care for indoor plant. They can be a bit sulky when neglected and you will see her leaves will droop, but dont worry, she should go back to her usual self with some care!
The Kokodama is a "husk" container where water may seep through if over watered. If you feel the husk getting very dry, soak the entire husk in water for a Few minutes.
No direct light for this baby - if you se her leaves fade then you know she needs brighter light.
They like a damp and airy environment but do not want their roots to be waterlogged. As a guide, water twice a week. Rather water less and more often. Watering also depends on how much light she is getting - more light, more water. In winter, water less.
The fittonia love a good feed, it will brighten her leaves and ward of any pests - dilute the fertiliser quite a bit, nothing too strong.
They are non-toxic!
