Hope that helps 😊
Give it a really good soaking, allow to drain out the bottom and repeat - if the compost/soil is dry you might need to do this several times, then give it a liquid seaweed or similar feed. Wipe off as much of the scale as you can. I can’t get methylated spirits here, but I believe if you wipe with that, that works.
However, if you paid a small fortune for it, complain to your supplier - it doesn't sound as if it has been well cared for...
Still, it was a great shame to see beautiful mature specimens dug out for other crops, or worse, for golf courses that then didn’t get built. The OP’s tree is probably one of those, as I doubt it would be commercially viable to grow such ancient trees just for garden use. At least it has another life.
One important point, Louise, did it come from a reputable source with a traceable phytosanitary certificate? Currently, thousands of olive trees infected (or at risk of being infected) with the devastating xylella disease are being dug up and destroyed. It wouldn’t surprise me if there was a black market export trade in trees that should have been incinerated!
Depending on your location, especially if your soil is well-drained, it would come through winters better in the ground if you had a suitable sunny, sheltered spot and you mulched the base well. Olive trees in the ground regularly took -12ºC where I used to live.
I have a very large, old ornamental specimen that does fine in the ground here, in a mountain climate, planted in heavy, poorly drained clay, exposed to fierce winds, very hot summers, often freezing winters and occasional heavy snow falls. By all measures, it shouldn’t survive but it does.
Anyway, good luck and enjoy your tree.
I have a villa in Andalucia and we have a lot of olive trees. Yes your issue it is olive scale. But don't panic you can help the tree fight it off. You can use a tree/bark wash and there are a few specific scale treatments you can buy - let me know if you haven't found any yet and I can point you in the direction of a couple. You will need to invest in a proper large sprayer to apply this. Scale is hard to get rid of and all the treatments only work by direct contact so you have cover the leaves above and below and gently wash the trunk.
