Olive tree: Brown tips on leaves
I received a potted, indoor olive tree as a gift in August 2021 (see photo 1). I put it in the sunniest window, although I live in London, England and it isn't a sunny place. In the spring it started to grow (south facing window) and I was very happy. Until I realized the new growth was turning brown on the leaf tips a few weeks after starting to grow. Many of the brown tipped leaves would also fall. I tried watering differently (soaking once a week), but it didn't seem to help. I bought soil recommended for olive trees and repotted it, in a slightly larger pot that is terra cotta, rather than the original plastic. To no avail.Then I tried giving it an olive fertilizer this year (summer 2022), but the problem persists. Can anyone help? I've seen very conflicting advice online and I'm desperate to figure out the true problem and get her back on track!
