Troubleshooting
Eaton's Firecracker problems — and how to fix them
Eaton's Firecracker (Penstemon eatonii) 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 failure outside its native range. Ensure the planting site has perfect drainage — slopes, raised beds, or gravel gardens. Avoid any supplemental irrigation in winter.
Short-lived in unsuitable climates
Typically lasts 3–5 years even in ideal conditions. Treat as a short-lived perennial and maintain a seed supply. Self-seeds in warm, dry garden settings.
Aphids on new growth
Occasionally attacked by aphids in spring. A strong jet of water or insecticidal soap spray is effective. Healthy plants in lean soil are rarely seriously affected.
