Why Are the Flowers on My Impatiens Falling Off?

1. I Am Thirsty (Water Stress)

From my roots' perspective, this is the most common plea. My delicate, succulent stems and leaves are mostly made of water. When the soil around me dries out, I enter a state of survival panic. I must prioritize my resources to keep my core alive—my stems and leaves. Supporting and hydrating large, vibrant flowers takes a tremendous amount of energy and water. If I am not receiving consistent moisture, my self-preservation instinct kicks in. I will abort the blossoms, a non-essential part in a drought, to conserve all available water for my vital tissues. This is my way of saying, "A deep, regular drink, please, especially in the heat!" Conversely, if my roots are sitting in soggy, waterlogged soil, they can't breathe. Rot sets in, they fail, and they cannot transport water up to my flowers, causing them to drop as well.

2. I Am Hungry (Nutrient Deficiency)

Producing these beautiful, colorful blooms is an exhausting process for me. It requires a significant and steady supply of nutrients, particularly phosphorus, which is crucial for flower development and blooming. If I am planted in poor soil or if the nutrients in my container have been depleted, I simply do not have the strength to sustain my flowers. I might manage to bud, but without the nutritional foundation, the flowers will be weak and I will be forced to shed them prematurely. Think of it as me trying to run a marathon without any breakfast; I will collapse before the finish line. A balanced diet is key to my floral show.

3. My Environment Is Wrong (Temperature and Light)

My ideal world is one of dappled sunlight or bright shade. If I am subjected to intense, direct afternoon sun, I become severely stressed. The sun scorches my leaves, dries me out too quickly, and the sheer heat can cause my delicate flowers and buds to wither and fall off. On the other hand, if I am placed in deep, full shade, I cannot perform photosynthesis efficiently. Without sufficient light to create energy, I cannot support the very process of flowering. I will become leggy, weak, and will drop my buds because I lack the basic power to open them. I need that perfect "Goldilocks" zone of light—not too much, not too little.

4. I Am Under Attack (Pests and Disease)

Sometimes, the issue is an invisible invasion. Tiny pests like spider mites, aphids, or thrips may be feasting on my sap, particularly from the tender stems and buds. This sucking action weakens the connection between the flower and the stem, causing it to drop. Furthermore, I am notoriously susceptible to a disease called Impatiens Downy Mildew. This fungal-like pathogen attacks from within, often showing no obvious signs at first except for leaf curl and a sudden, dramatic dropping of all flowers and leaves. It is a systemic issue that I cannot fight on my own, and it forces me to shed my beautiful parts in a desperate, but often futile, attempt to survive.

5. I Am Just Resting (Natural Life Cycle)

Please remember that each individual flower has a natural lifespan. After I have been pollinated or after a flower has simply aged, it is my natural process to let it fall away. This allows me to redirect energy into producing new buds and flowers rather than sustaining old ones. A gradual, occasional dropping of spent blooms is completely normal and is part of my cycle. It is how I make room for new growth and continue my show throughout the season. This is a healthy process, not a cause for alarm.
