Petunias Wilting and Dying: Water, Fungus, Drainage, and Slugs

Gardener transplanted mature petunias into Miracle-Gro soil in hanging baskets. Most failed. Tried not to disturb roots. Asks if should have cut stems/roots.

Possible Causes (Mike)

• Transition shock: no gradual hardening (shade for few days before full sun).
• Baskets dry fast; need frequent watering.
• Suspects rapid transition + inadequate water.

Also general petunia death causes: need 1.5" water/week (more in heat), mulch with straw/clippings. Amend soil yearly with organic matter. Avoid overwatering (rots roots, especially in clay). Slugs eat stems—control with Escar-go or Sluggo.
