Young olive trees may require fertilizing after planting, depending on the time of the year (see below). Established olive trees require fertilizer to stay healthy and produce every year. They need a balanced fertilizer with a 16-16-16 nitrogen, phosphorus, potassium ratio or similar.

When should I feed my olive tree?

Olive trees in pots are heavy feeders comparing to wild olive trees due to their root restrictions in the pot. So it is best to fertilize them every 4-6 weeks during their active growing season (spring and summer). And every 1-3 months during the dormant period (fall and winter).
