Cultivation: Watering Needs: Its thick taproot is susceptible to over-watering.  Sometimes it's grafted to avoid root rot problems.
Frost Tolerance: 
It likes warmth (recommended minimum winter temperature 5° C).  But a plant kept perfectly dry can easily survive at winter night temperatures below 0° C.
Sun Exposure: Suited for sunny-bright exposure; but can tolerate light shade. Suited for airy exposures.  It needs a deep pot and good drainage to accommodate its tap root.  Keep dry in winter.
Pests & diseases:   E. napina is especially prone to rot, therefore, underpot in a smaller container filled with very porous compost.

Propagation:
 By seeds or graft. Seeds can be sown in the spring or summer. The seedlings should not be disturbed until they are well rooted, after which they can be planted separately in small pots.
