Why Do Anthurium Flower Buds Turn Black

1. Metabolism

Cause: When it grows to a certain point, its flower buds gradually turn black, usually because the flowering period has lasted too long.

Solution: This is generally normal metabolism, not disease, and will not harm the plant, so there is no need to worry too much. Just wait patiently, and the flower buds will slowly return to normal.

2. Reduce Watering

Cause: When growing it, the substrate used is usually peat soil, which has very strong water retention, but once the soil dries out it does not easily absorb water again. So if it is watered too much, water tends to accumulate in the pot. When the roots sit in standing water for a long time, root rot begins, and they can no longer supply nutrients to the flower buds, so the buds slowly turn black.

Solution: At this point, watering should be controlled. Water when the substrate is slightly moist, not when the soil is completely dry or waterlogged. The surface peat soil can be used as a watering signal: once it dries, watering can resume. This is what allows it to grow better.

3. Proper Fertilization

Cause: During its growth, in order to make it grow faster, we keep fertilizing it, or use highly concentrated fertilizer. This easily burns the roots and causes them to rot, and over time the flower buds are affected as well and slowly begin to turn black.

Solution: At this point, water can be used to dilute it, and fertilization should be controlled.
