Pest identification
What's eating my white stonecrop?
Aphids
Signs: Soft white or green insects crowd shoot tips, causing yellowing and sticky honeydew that promotes sooty mold.
Control: Spray forcefully with water; apply insecticidal soap or neem oil; introduce natural predators.
Vine weevil
Signs: Root grubs hollow out stems at soil level, causing wilting patches; adults leave notched leaf margins.
Control: Apply pathogenic nematodes (Steinernema kraussei) to moist soil in late August; inspect roots when dividing clumps.
Slugs and snails
Signs: Shiny slime trails and irregular holes in fleshy stems, worse after rain in spring.
Control: Set iron phosphate bait; hand-pick at night; avoid excessive mulching around the crown.
