Medium light
He likes a spot that’s bright but out of direct sun. He’ll be ok in a bit of shade too.
Regular watering
Because his roots are in water, you just need to keep that water topped up, but keep the top parts of the roots out of the water. 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.
