What's eating my roller jovibarba?

Roller Jovibarba is a tough, cold-hardy rosette succulent whose characteristic offsets roll away to propagate themselves. Vine weevil is the primary pest concern — grubs silently devour roots, and the first sign is a rosette that lifts from the soil with no roots attached. Mealybugs can occur on pot-grown plants. Overall it is highly pest-resistant when grown outdoors.

Adults notch leaf margins at night; grubs eat roots causing entire rosettes to detach from soil without warning Water in biological nematodes (Steinernema kraussei) in spring and early autumn when soil temperature exceeds 5°C; repot annually to inspect roots and remove any grubs found

White waxy residue tucked between the tight rosette leaves, mainly on indoor or protected container specimens Remove with a cotton swab dipped in 70% isopropyl alcohol; spray with insecticidal soap; isolate from other plants during treatment

Occasional colonies on flower stems in summer; honeydew and distorted bloom stalks are the signs to look for Spray with insecticidal soap or knock off with a strong jet of water; outdoor colonies are usually controlled quickly by natural predators
