Why Don't Dendrobium Orchids Bloom
Let's talk about the reasons why Dendrobium orchids don't bloom, some knowledge about flowers, let's take a look together.
Why Don't Dendrobium Orchids Bloom
Dendrobium orchids fail to bloom due to low air humidity, excessive sunlight, and improper fertilization. During the growth of Dendrobium orchids, they require sufficient air humidity, usually around 80% is optimal. In summer, proper shading measures should be taken, and phosphorus-potassium fertilizer should be applied before the blooming period to accelerate the differentiation of flower buds, resulting in more vibrant and numerous flowers. After the blooming period, a dilute liquid fertilizer can be applied.
Reasons Why Dendrobium Orchids Don't Bloom
1. Air Humidity: Dendrobium orchids have high requirements for air humidity during their growth. If the air humidity is too low, it cannot meet the plant's growth and blooming needs, which can affect its growth and even prevent blooming.
2. Sunlight: Dendrobium orchids cannot be exposed to strong sunlight, as it can easily burn the plant. Under strong sunlight, it can affect their blooming.
3. Fertilizer: Dendrobium orchids require a large amount of fertilizer, especially during the blooming period from April to May. If an adequate amount of phosphorus-potassium fertilizer is not applied, it will affect the differentiation of flower buds, thus affecting normal blooming.
Methods to Deal with Non-Blooming Dendrobium Orchids
1. During the growth of Dendrobium orchids, they need sufficient air humidity, usually around 80% is optimal. Additionally, a spray bottle can be used to spray water around the plant at regular intervals to maintain higher air humidity.
2. When growing Dendrobium orchids, if the light is too strong, it is necessary to provide appropriate shading, allowing some scattered light or no light at all, so that the plant can grow better and bloom more flowers sooner.
3. The peak blooming period of Dendrobium orchids is from April to May. To encourage more blooming, phosphorus-potassium fertilizer should be applied before the blooming period to accelerate the differentiation of flower buds, resulting in more vibrant and numerous flowers. After the flowers have bloomed, a dilute liquid fertilizer can be applied to replenish the nutrients consumed by blooming.
Blooming Time of Dendrobium Orchids
The blooming period of Dendrobium orchids is long, lasting from January to around June, totaling about half a year. They have high ornamental value. To make them bloom better, careful maintenance is needed, especially good temperature control. It is best to keep the temperature between 15-20 degrees. Too high or too low temperatures can hinder blooming. Attention should also be paid to humidity; during dry weather, not only should more water be浇ed, but also frequent spraying is necessary.
The above is the specific content regarding the reasons why Dendrobium orchids don't bloom, for everyone's reference and operation.
