What's wrong with the black core of the rose
The black core of a rose may be caused by long-term exposure to rain, leading to the contamination of the flower bud by rainwater, or it might be due to insufficient lighting provided during the care of the rose, resulting in poor growth, rotting of the flower bud, or it could be that the rose suffers from a disease during its growth, causing the flower bud to rot and turn black.
1. -- Long-term exposure to rain --
When roses are exposed to rain for a long time during flowering, it causes rainwater to accumulate in the rose flower bud, leading to contamination and blackening of the flower bud. Therefore, it is necessary to take appropriate rainproof measures for the plant during the later care of roses. It is best to place the roses under the eaves or indoors on rainy days.
2. -- Insufficient lighting --
Roses thrive in environments with ample light. If roses do not receive enough light during their growth, they may also experience rotting of the flower bud and blackening of the core. Therefore, it is necessary to provide them with suitable lighting during the later care of roses so that the plants can photosynthesize normally and grow better.
3. -- Over-fertilization --
Roses have a relatively low demand for nutrients during their growth. If nutrients are provided too frequently for roses, it can lead to fertilizer damage and blackening of the flower core. Therefore, it is necessary to provide the roses with an appropriate amount of nutrients during the later care, preferably by diluting the fertilizer before providing it to the plant, allowing the roses to bloom better.
4. -- Affected by diseases --
If roses are affected by diseases during their growth, it can also lead to the contamination of the flower bud by pathogens, resulting in blackening of the flower core. Therefore, it is necessary to take appropriate measures to prevent and treat diseases during the later care of roses. It is best to spray a disinfectant on the roses every three days to help the plant recover normal growth as soon as possible.
