Two-Row Stonecrop problems — and how to fix them
Two-Row Stonecrop (Sedum spurium) 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.
Root and crown rot
The primary cause of death. Heavy clay soil or persistent winter wet kills the crown. Always plant in well-drained or gritty soil and avoid mulching over the crown.
Weedy spreading
Stems root where they touch soil and can become invasive in borders. Contain by pulling back runners annually or growing in confined raised beds and wall crevices.
Aphid infestations
Aphids sometimes cluster on flower stems in summer. Blast off with water or use insecticidal soap; beneficial insects control most outbreaks in a healthy garden.
