What's eating my pyrenean ramonda?

Ramonda myconi is virtually disease-free and generally pest-resistant, but its fleshy rosette leaves are irresistible to slugs and snails in shaded, damp rockery conditions. Indoors or in alpine houses, mealybugs occasionally attack leaf axils. Keeping foliage dry and providing good air circulation prevents most problems.

Ragged holes in the soft, crinkled leaves; silvery mucus trails across the rosette and surrounding rock or soil Apply horticultural grit or crushed eggshell around the plant; use iron phosphate-based slug pellets; check under rocks and debris at dusk and remove pests by hand

White cottony deposits tucked into leaf axils or along stems; leaves lose color and vigour as sap is extracted Remove with a cotton swab dipped in isopropyl alcohol; treat weekly until clear; ensure plants are not overcrowded to aid inspection

Colonies of soft-bodied insects on young growth and flower stems; leaves may distort; sticky honeydew attracts sooty mold Knock off with a soft paintbrush or diluted water spray; if indoors, apply insecticidal soap carefully avoiding the leaf hairs; inspect regularly in spring
