Impatiens Rotting in Flower Boxes: Drainage, Soil & Watering Fixes

Impatiens in NE-facing flower boxes rot at roots. Cutting back water didn't help. Boxes likely lack drainage, use old soil, or have garden soil added.

Checklist for Success

1. Drainage holes: Essential. No holes = waterlogged soil.
2. Fresh potting soil yearly: Old soil clogs drainage, harbors fungi.
3. No garden soil: Heavy, fungus-laden. Use quality potting mix.
4. Watering: Morning preferred. Test soil—water when dry or pulled from sides. Cool nights = less frequent watering.

If Rot Started

Fungi continue even after watering reduces. Best: start over with new soil, new plants, proper drainage. Impatiens are excellent for NE boxes when conditions are right.
