olive tree not flowering (forum)

I planted a seedling olive tree about 8 years ago. It is yet to flower. When should it start flowering/producing fruit? Is there anything I can do to encourage flowering?

Hi Sarah, try giving it some fertilizer high in Phosphorus (P) and Potassium (K), and give it a good dressing of Gypsum, then mulch heavily, but keep it away from the trunk, ~ 200mm. A small prune will help too.

Hi Brendan
Noticed your from Mackay. Have you managed to get an olive to fruit here? I thought they needed a higher chill factor than we would get.

Hi Lisa, my olive tree grew well for ~ two years 'till we got that flood in '08. I just planted it in the wrong place too, which didn't help. They don't bear too well here, but over the range they do. If I ever bought another one, I'd plant it on a mound of sandy loam, lots of Gypsum, old or composted cow or horse manure and mulch heavily. I'd also let it grow for ~ six months, then give it some 'P' & 'K' fertilizer to help it flower.

Hi Marvin,
Sounds like it's getting too much Nitrogen? To help it flower, give it some Sulphate of Potash fertilizer. A handful / sq metre under the canopy spread. They don't mind a bit of Gypsum either.

Thank you Brendan for keeping this thread going with your advice. Is there a natural way to add the P, K and potash to encourage flowering?

Thanks in advance
Sarah

Hi sarah,
Natural phosphate rock dust is available and sulphate of potash is 'usually' dug straight out the ground. I would give it more K (sulphate of potash) than P (phosphorus).

Have you done a pH test on your soil?
