What are the reasons why leaf flowers do not blossom

What is special about the leaf flower is that its bracts are large and beautiful, so it is often mistaken for its leaves to be petals, so it gets its name. Some flower friends also plant their own flowers because they like this characteristic. But in the process of raising, some flower friends' leaf flowers will not blossom, or blossom is rare, what is the reason for this?

Leaf flower (details)

1, lighting problem: this is relatively easy to investigate, the leaf flower is a positive plant, the growth period requires sufficient light. The stronger the sunshine, the more beautiful the flowers. On the contrary, if you grow in a dark environment for a long time, you will not blossom.

2, fertilizer problem: potted flowers will face the problem of fertilizer, especially woody flowering plants, the demand for fertilizer is greater, according to the size of potted plants, generally once a month, liquid fertilizer should be applied every half a month during the peak growth period of leaf flowers, and more can be applied if the environment temperature is higher. The application of more phosphorus and potassium fertilizer is beneficial to the differentiation of flower buds and ensure the growth of flower buds.

3. The problem of watering: there is a saying that "frequent water does not blossom, less water keeps falling". Water control can make the flower bud differentiation of leaf flowers to a large extent affected by the amount of water. Generally speaking, water control should be carried out about 50 days before flowering. In other words, if we want the leaf flowers to blossom on the National Day holiday, we should begin to control the water on August 10. If you encounter a rainy day, you should move it into the greenhouse or cover the rain film to prevent the basin soil from dripping with water. The time of water control was about 10 days, when the epidermis of the branches of the same year were a little wrinkled. After that, it will be watered again and managed normally, when the leaves and flowers will fall off the old leaves and sprout.

4. The problem of pruning: some flower friends are unwilling to prune, resulting in scattered nutrients and not easy to form flower buds. Leaf flowers can cut off some weak branches and diseased branches when they have flower buds every spring, and cut off the pedicels after flowering.

The reason why gardenia doesn't bloom, what if gardenia don't blossom?

Gardenia does not bloom for just a few reasons. Generally speaking, the leaves of gardenia are evergreen all the year round, the flowers are fragrant and elegant, and they look particularly beautiful and lovely, so they are loved by many families. Its florescence is in spring and summer, and it can continue to bloom from May to August, but sometimes the gardenia we plant do not blossom. Here are the reasons why the gardenia does not bloom and how to deal with them.

Gardenia flower does not bloom reason 1. Gardenia flower does not blossom reason: the soil is not suitable

Gardenia likes acidic soil, the land in the north is alkaline, the soil will be affected for a long time, lack of nutrients, gardenia will not blossom naturally.

Solution:

Usually, when watering, you can add some ferrous sulfate to improve the soil, and you can often apply 10% alum fertilizer as topdressing, and you can also put acidic fruit peels such as pineapple, orange and grapefruit in the soil after fermentation.

2. The reason why gardenia does not blossom: less fertilization.

Gardenia likes fertilizer, if the fertilizer is insufficient, it will lead to poor plant growth, there is no nutrient supply for flowering. Once excessive water and fertilizer, it will cause plant overgrowth, growth without enough nutrients will affect the formation of flower buds, resulting in no flowering or little flowering, some blooming, or even immediately fall off.

Solution:

A, the growth period of gardenia should apply more rotten cake fertilizer, about 10 days fertilization. Potassium dihydrogen phosphate solution was sprayed once a week from April until buds appeared in most branches of Gardenia jasminoides.

B. after budding, the root was watered with potassium dihydrogen phosphate twice to enhance the stress resistance of the plant and make the plant blossom larger and more fragrant. If the bud is found to crack and show white, it is necessary to stop fertilizing.

3. The reason why Gardenia does not blossom: the light is not adapted to it.

The light is not suitable, gardenia likes shade, we should pay special attention to the strong light in summer and too weak light in winter, too strong and too weak will affect the blooming of mast flowers.

4. The reason why Gardenia does not blossom: the branches are not pruned.

Non-pruning and shaping, cluttered branches of Gardenia jasminoides, a large number of miscellaneous branches consuming a lot of nutrients and branches too dense, affecting photosynthesis are all important reasons for non-flowering.

Gardenia flower does not blossom what to do 1. Slightly sour soil

Gardenia grows mostly in the south, and it is common in the suburbs or mountains. Rain Water is more in the south, so he likes acidic soil. Potted flowers can consider this factor. When watering, we can consider adding ferrous sulfate to improve the quality of the soil.

2. Plenty of sunshine

Many people keep potted plants in places where they can't see the sun. They can provide proper shade in summer and direct sunlight in other seasons.

3. Fertilization before flowering

Application of corrosive cake fertilizer in growing season and phosphorus and potassium fertilizer in flowering season

Why the leaf flower does not blossom (scientific name: Bougainvillea spectabilis Willd.), purple jasmine family, leaf flower belongs to woody rattan shrub, stem has curved thorn, and densely tomentose. Simple leaves alternate, ovate-entire, thickly tomentose, apex obtuse. The flower is very small, yellowish green, three gather in three red bracts, the outer red bracts are large and beautiful, with bright red, orange, purple, milky white and so on, which are mistaken for petals. Because they are shaped like leaves, they are called leaf flowers. The florescence can be from November to June of the following year. In winter and spring, the colorful bracts are displayed, giving people an unrestrained and warm feeling, so it is also named he Chunhong.

Leaf flowers do not bloom, there are mainly the following reasons: 1, unreasonable fertilization. Long-term application of too much nitrogen fertilizer to leafy peanuts will lead to the growth of vegetative organs, while the lack of nutrients in cultured organs will affect flower bud differentiation and lead to no flowering. Flower fertilizer with more phosphorus should be applied during flower bud differentiation, and 0.2% potassium dihydrogen phosphate can be applied every 15 days. 2. Excessive nutrient consumption. Leaf flower branch rate is high, such as disrepair, will cause branches to grow, consume a lot of nutrients, not only destroy the tree shape, but also affect flower bud differentiation. Generally speaking, it can be trimmed twice a year. Once is combined to change the basin, cut off the base too dense branches, weak branches, disease and insect branches and only long branches. The top tip of the retained branch should also be cut off. On the other hand, the withered branches, over-dense branches and internal branches were cut off before the new shoots grew after anthesis, and only the top part of the horizontal branches was cut off. In the process of new branch growth, the top tip should be cut off in time to promote the formation of new branches in order to form more flower buds. Too high room temperature in winter will break dormancy, and branches and leaves will not blossom too early. 3. Unsuitable light temperature. Leafy flowers are native to tropical South America and are short-day light-positive plants. Under the condition of long sunshine for a long time, the flower bud can not differentiate normally, which affects the civilization. The leaf flower is not tolerant to shade, likes warm and humid environmental conditions, and is extremely not resistant to cold. The suitable temperature for giving birth to a third party is 20 Mel 30 ℃. If the room temperature is lower than 15 ℃ in winter, it is disadvantageous to health.
