Olive plant (lives in balcony) got covered with black insect shell like things I have this Olive tree for almost 7 years now. Generally was in ok condition. I water based on soil dryness, not on calendar. It has good sunlight all around, 4-5 hours direct afternoon sun, but is on light spot all the time in balcony. It hat couple of those things also on last but was really just couple. This year it is a full infestation. It also leaked this sticky things too, which may be related. I can pick them without harming the bark, but there are thousands of them and I will like to know how I can prevent it Originally by u/Horkosthegreat on Reddit: https://tinyurl.com/27n52s77
