What is eating my euphorbia bupleurifolia?
Euphorbia bupleurifolia (pineapple euphorbia) is a rare, slow-growing succulent most at risk from mealybugs sheltering between its leafy rosette and the textured caudex scales, and from root mealybugs in poorly drained soil. Spider mites can appear in dry air. Its rarity makes pest damage especially costly — inspect at every watering.
