Marks on Olive Tree Leaves

Posted by nadaud_1981 (My Page) on

Hello. I purchased an olive tree from a local nursery a few weeks ago, and it is doing magnificently. But I have noticed that one or two of the leaves have these sort of tiny indentations, or pits, about half the size of a pinhead on their undersides. The pits themselves are the same color as the undersides of the leaf. When I shine a flashlight through the back of these leaves, I see a lot of tiny black dots, presumably where the indentations are. It should be noted that I just removed a scale insect from one of the branches, but I'm not sure if these are just wounds from that, or a fungal attack. The humidity in here is very low, and I only water when the soil is nearly dry. The tree also receives adequate air circulation. I am unable to post any pictures, as I do not own a camera at this time, but any help would be appreciated. Thank you.

What is the Latin name of your plant? People commonly grow Olea and Osmanthus as houseplants, often referring to the latter as 'olive ' or 'sweet olive '. It MIGHT help if we know what kind of plant this is, as well as your general location.

Olea europaea is the Latin name, but I'm not sure what cultivar or subspecies it is or anything like that.
My location is Zone 4, in southeastern South Dakota. My apartment generally stays a lot warmer than it is outside, as I live near the top floor of a taller apartment building.

nadaud, I'm going to suggest that you post this question in the Houseplant Forum; I've seen several people there who grow Olea europaea as a house plant. Perhaps one of them will recognize these symptoms from their own experiences.

It's going to be difficult to get a diagnosis without some sort of picture, but the Houseplant Forum is the place to start.

Okay, I'll try posting there. Thank you for your help.
