Multiple Plants Dying in Garden: Suspect Fungal, Drainage, or Rodent Issues

A Red Flame bush died, now a large rhododendron has curling leaves. Gladiolus, hollyhocks, and delphinium also died. Site has plenty of water, good drainage, and supported plants well until two years ago.

Possible Causes

• Fungal/drainage issue (wide variety of plants affected).
• Herbicide damage.
• Vole/shrew/field mouse damage (look for dime-sized holes, gnaw marks at plant bases).

Action Plan

1. Take dead/dying plants with roots and a soil sample to a local nurseryman. They know local soil diseases, can test soil, and assess texture.
2. Check for rodent evidence; bird feeders attract voles/mice.
3. Apply a good fungicide and improve bed tilth and drainage.
4. Use plants less susceptible to root diseases; nurseryman can recommend.
