Why Don't Sempervivum Flowers Bloom
Let's understand the reasons why Sempervivum flowers don't bloom in this green plant and flower cultivation content.
Why Don't Sempervivum Flowers Bloom
Sempervivum flowers don't bloom due to excessive application of nitrogenous fertilizer, unsuitable lighting, and inappropriate temperature. Reduce the application of nitrogenous fertilizer, increase the application of phosphorus and potassium fertilizers, extend the plant's exposure to light, ensure it receives at least 4 hours of direct sunlight daily, maintain even lighting by rotating the pot every few days, and keep the cultivation temperature between 5-25 degrees Celsius, preferably around 15 degrees.
Reasons for Sempervivum Not Blooming
1. Excessive Application of Nitrogenous Fertilizer: Sempervivum has two growth modes, one is vegetative growth, and the other is reproductive growth. If only nitrogenous fertilizer is applied during cultivation, it will undergo vegetative growth, and most of the nutrients will be concentrated in the growth of branches and leaves, not for flowering.
2. Unsuitable Lighting: Sunlight is also an important factor affecting whether Sempervivum blooms or not. It not only needs sufficient light but also even lighting, otherwise, it may lead to the plant not flowering.
3. Inappropriate Temperature: Sempervivum prefers a warm environment and is not cold-tolerant. If the cultivation temperature is not suitable, Sempervivum will find it difficult to bud, resulting in no flowering or less flowering.
Methods to Deal with Non-Flowering Sempervivum
1. If the non-flowering of Sempervivum is due to excessive application of nitrogenous fertilizer, reduce the application of nitrogenous fertilizer and increase the application of phosphorus and potassium fertilizers, which will make it switch to reproductive growth and bloom better.
2. Sempervivum thrives in a sunny environment. Increase the plant's exposure to light, ensuring it receives at least 4 hours of direct sunlight daily. If the light intensity is insufficient, extend the exposure time. Also, ensure even lighting by rotating the pot every few days and keep the temperature between 5-25 degrees Celsius, preferably around 15 degrees.
Blooming Time of Sempervivum
The blooming time of Sempervivum is from December to the following April, with a long flowering period of 4-5 months. Some varieties can bloom from January to May. Its flowering time is not fixed and can be affected by climate, region, and variety.
