Though olive trees are self-fertile they are wind pollinated so should to be outdoors whilst in flower if you’re hoping to grow fruit. 
A hole should be twice the size of the pot, and approximately the same depth. Before placing the root ball into the hole, straighten and/or trim the coiled roots. Don’t bury it plant deeper than it was in the pot. You only want a few inches of soil above the root system and you don’t want to disturb the roots too much. You should not slow-release soil. Fertilizer at this time. Please fill out the planting hole in with the native soil and water deeply. Place 4-6 inches of mulch over the root zone.

The fertiliser should be used around the tree’s root. Continue feeding every few weeks throughout the growing season Vitax Q4 (or seaweed extract) are the best options. In late July you should stop feeding as new growth is vulnerable to Winter damage. Like most containers-grown plants, olive trees in pots require more nutrients than ones in open ground. But be careful not to overfeed. Cause excessive green growth. (We thank Vikki for sharing this information with us).
