Kalamata olive tree not produging fruit (forum)

Louis R starts with ...
I have 3 beautiful Kalamata olive trees two of them 14 years old and one 8.Come early spring and they are full of flowers but seems there is a polynation problem as very few fruit are produced although excelent quality.I was told to feed some Dolomite or garden lime around the tree. I checked it at PH 5.5 I was born near Kalamata and I am familiar with the cultivation of the tree but I never came across this problem before and people that I know near by have the same problem. However the tree was producing fruit, of another variety before I grafted it to Kalamata. Any solutions ? Also Tomatoe maggots. Is the fruit fly treatment applicable or is there something else. Thanks Louis

Louis, I'd give those trees some Phosphorus (P) & Potassium (K) & a bit more Dolomite, as ph 5.5 is too acid.
Try spraying your tomatoes with 30g Copperoxychloride to 4.5 L water with a good wetting agent like Spreadmax or Kenwet 1000 L.F. The fruit fly doesn't like the copper.

Brendan, thanks for your advise.You are the third person suggesting increase in dolomite, and Potassium(k) of course helps with fruit production. I will try it and let you know of the results.

I have exactly the same problem as you Louis, except with much younger trees - 4 years old. The non-fruiters are all grafted Kalamatas with a very strong vertical growth pattern. Not sure what they are grafted onto. Grower says be patient, but I have other trees nearby including a jumbo kalamata producing fruit at 2 years old....do not understand at all and worried that somehow I have bought non-fruiting olives,

I have an 8 yr old Kallamatta tree in western sydney and have not had any fruit to date. Was initially told to put in well drained area and not to fertilise. Have done so, the tree is 5 metres high and strong, but never a sign of fruit. It is near a large gum tree, but this has not effected it's growth
Any ideas. I have citrus, mulberry, and stonefruit trees in the immediate vicinity, and all are going great
Cheers

How did adding dolomite go? My kalamata olive tree was extremely disappointing last season. From huge numbers of little flowers i got 6 or 7 olives that didn't end up making it to full maturity any way. Do they need a cross polinator?

I am sure that someone has already mentioned this, but olives do have on and off fruiting years.

I did see a label for a kalamata which gave the name of a pollinator. I did take a photo of it, but my phone crashed and I lost them all.
Maybe google?

I have three olives, which I think are all the same kind. They all produce a large black fruit, which my SIL says is delicious. :) I don't like olives, so I'll take her word for it.

They didn't fruit at all for the first 8 years or so. Or, at least, they produced one or two here or there, but not enough to be bothered with. Last year, and this year, they've produced enough for us to pick and process. We got a bucketfull last year and slightly less this year as we pruned them in anticipation of a really hard summer (no watering to speak of, as we've been building on that block). They still produced though, but they're looking happier now that it is cooler and the rains have started.

I didn't know that olives needed a polinator. Are there any that are self-fertile, or are happy with a same kind polinator?

Question for Steff Heinze - you mentioned that you had a jumbo Kalamata already producing olives. My jumbo Kalamata had its first crop of olives but they were very small, not at all like the descriptions of this olive which is supposed to be very large. Were your olives large right from the first crop? Or did you have to wait for later years to get large olives?
