Your Croton LOVES the sun and would really quite like to bask in it all day. Your efforts will be rewarded with stunning colours.
She will enjoy a good watering in a pot with plenty of drainage. Let the top of the soil go dry in between waterings as she won’t appreciate being over watered.
Croton Nervias are a tropical plant so would love a good dose of humidity. You can pop her in the bathroom, a warm conservatory or even in an indoor swimming pool (if you’re swish like that). Give her going over with a regular misting.
She likes the warm, so keep her warm. 17 degrees and above will keep her in best shape.
If you want to feed her then you can feed her once in early spring and then once again in late spring.
Unfortunately she is a toxic species. So keep her away from pets and small children.
