In Sout Africa, there is a naturalized or endemic species that does not produce berries in such large quantities as the European elder and hence we prefer to grow the European variety.
These shrubs or small trees need lots and lots of compost and will have stunted growth if this demand is not met. For this reason, we plant our elder berries right next to the compost heap where their roots can access the compost teas that leach out of newly formed heaps.
They need full sun and will not tolerate too much shade. Once established, a deep watering every 2nd week should be sufficient, but more water will mean more growth.
