Why Impatiens Stop Blooming in Late Summer: Light Angle Changes

Likely Cause

Animals don't eat just the flowers. The front-to-back bloom loss suggests the sun angle has dropped, shading the bed progressively. Impatiens need at least 3 hours of direct sun to bloom well. Observe the bed for a day to confirm.

If Sun Is Adequate

If the bed still gets 3+ hours direct sun, write back for further brainstorming.
