Euphorbia obesa dying

Question

here i have euphorbia obesa with root mealybugs i guess. this plant was alright few days ago. could mealybugs do this in such a short time? two weeks ago i moved the plant to more sunny part of the greenhouse,and that was the only change the plant experienced since summer,btw,she was on almost direct sunlight all summer,so she is used to it i guess,and was looking really healthy and not minding the sun. i didn’t water it since summer as well.the other obesa that stays right next to it has mealybugs as well but looks quite healthy and not affected at all.so…what’s wrong here?

Answer 1

Yes. This could, certainly, be mealy bugs… I would recommend watering with peroxide at half strength, and spraying with neem oil.
