Olive Tree - yellowing of leaves problem

Hi, I recently purchased an Olea Europea (Italy region) which I repotted to a larger pot while keeping its original clay like soil, mixed with fresh soil. I've been watering it every 3 days for the last 3 weeks as its been 29 degrees and its in partial shade. Im also using a moisture sensor to ensure the soil is not too moist between watering. I'm noticing a small amounts of yellow leaves every couple days after watering it, which easily drop off. However they are mainly yellow on the base and veins of the leaves (see photos). I'm struggling to find anything online to understand what is causing it. Hopefully you can help me understand what is happening. Thanks

    Olive trees are evergreen, but the leaves do not last forever.
    Many evergreen plants shed some of their older leaves in the summer once they've grown some fresh new leaves and I suspect that is what you are seeing.

    I have one in a big pot - I water it about once a week and give it a seaweed extract feed about once a month whilst it is growing.

  • Hi Pete, thanks for your comments. To add on that, the leaves I'm seeing turn yellowish are young ones from the branches withing the centre on the tree, if that makes any difference. I been told to water it less frequently so I will try that and see if anything changes. Any further advise will be appreciated. Thanks

    The leaves in your pics all seem to be low down on the branches indicating they're older than the new leaves that grow at the ends of the branches.
    Watering every 3 days does seem a lot, but if it's in a relatively small pot it may need it.
    They're quite robust trees and the main disease they get on occasion is Peacock Spot, and your tree does not have that.
    See how it goes by adjusting the watering, but I don't think your tree has a problem.

  • Thanks Pete. For my understanding, the leaves age is not defined by their size? Sounds like young leaves are the ones at the tip of the branch, from you said. I've seen very small in size leaves fall out due to yellowing, hence why I said young leaves are falling off.

    Some mature leaves may be slightly larger than others - it's not related to the age of the leaves, it's more to do with the environmental conditions when they were formed.
    Sure, new leaves are tiny, but once mature they're all roughly the same size.
    Some of the oldest leaves will drop in the summer months which is what your tree is doing - perfectly normal
