Most light conditions
She’ll be happy in bright indirect light. Her favourite is a spot near a window.
Regular watering
Because her roots are in water you just need to keep that water topped up. Make sure the tops of the roots are not under the water and change it every few weeks to keep it clean.
Feeding
In spring and summer, add a little liquid fertiliser to the water. After a day or so, change the water to keep it clean.
