Newly Planted Impatiens Struggling in Cool Michigan Spring: Overwatering and Cold Soil

Michigan gardener planted impatiens 8 days ago in part shade, sandy soil amended with low-nitrogen garden soil. Watered daily, then every other day, plus rain. Cool (<70°F). Cocoa shell mulch. Leaves yellow/white, stems weak/translucent, breaking at base. Flats left unplanted look better.

Diagnosis

Overwatering + cold soil shock. Impatiens roots rot in wet, cool soil. Daily/every-other-day watering plus rain = saturated soil. Cool soil slows root establishment.

Fix

• Stop watering. Only water if top 1 inch dry.
• Next watering: deep soak, then wait for dry signal.
• Do not fertilize—worsens stress.
• Keep remaining plants in flats until soil warms (weeks).

Impatiens know soil temp better than air temp. Patience prevents loss.
