Please help save my olive tree... picture inc

[Canadalife]

Our olive is is not doing well at all . It has been loosing leaves and just not thriving. It wondered outside 2 years ago and has never recovered. It was outside all summer and I have just brought it in. It is one of a pair and the other is thriving...so I must be doing something right.

Many thanks for any advice.

Is it above a radiator? It might be too dry. Or the shock of being outside then indoors.
I leave mine out all year, but they’re larger than yours.

I don't think they need to go indoors unless you are quite far north. My olive is nearly as high as the house and we get temperatures regularly below -5 in the winter. Maybe better to leave it out and wrap it in fleece?

It is more likely to be drought or disease if it has deteriorated over the summer.

Do both plants get the same amount of sun, shade and water?

Sorry just twigged at your username

Canada is a bit colder than the UK

Thank you for the tips....we are in the U.K. fairly southern. I have moved them into an unheated conservatory. Any suggestions how to revive the poor thing. I don’t know weathe to feed it, water it, prune it or ignore!

Thanks

I’d water sparingly. If you feed now there’s the danger that new growth will put more stress on the tree. Don’t prune either.
Trees are quite robust and often go into a dormant mode if stressed, but bud in the spring.

Can you ease it out of the pot and look at the roots? It could have a case of vine weevil grubs eating them, in which case you will need to get rid of the little rotters, repot it and give it a dose of vine weevil killer. They are notorius for attacking plants in pots. Do the leaves have small notches eaten out of them, or on any nearby plants? The adult weevils are grey and quite cute-looking... until you know what they are.

You could find that there are white grubs in the soil, or a load of little creamy yellow balls (which are their eggs and need to be got rid of too).

If it isn't vine weevil or anything else eating the roots, you will probably need to wait it out until next year, give it protection against hard frosts and hope for the best. You can't feed it at this time of year, it's too late.
