Troubleshooting
Running Tapestry Foamflower problems — and how to fix them
Running Tapestry Foamflower (Tiarella 'Running Tapestry') 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.
Invasive spread
Spreads aggressively via stolons in ideal moist shade conditions. In smaller gardens, control by removing unwanted runners in spring. Useful as groundcover in larger woodland settings where it can naturalise freely.
Crown rot in wet winters
Standing water around crowns in cold weather causes rotting at the base. Improve drainage before planting and avoid heavy mulch directly on the crown. In clay soils, raise beds or incorporate horticultural grit.
Powdery mildew
Fungal growth appears in late summer especially in warm, dry spells followed by humid nights. Increase air circulation by thinning congested colonies and avoid overhead irrigation in the evening.
