Troubleshooting
Miniature Creeping Jenny problems — and how to fix them
Miniature Creeping Jenny (Lysimachia japonica 'Minutissima') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Drying out and wilting
The shallow, fine root system dries out very quickly in hot weather or porous substrates. Maintain consistent moisture by watering frequently and applying a fine mulch or grit dressing around plants. Self-recovers quickly after rehydration if not severely desiccated.
Leaf scorch in full sun
Direct afternoon sun causes pale, bleached patches and brown leaf edges. Move containers to a shadier position or interplant with taller specimens providing afternoon shade. In rock gardens, site on the north or east-facing side of rocks.
Slug damage
The tiny, soft leaves are highly attractive to slugs, which can decimate a mat overnight. Apply diatomaceous earth around the perimeter, use iron phosphate pellets, and check for slugs after dark. Container planting on raised benches reduces risk significantly.
