The gentleman orchid has been raised for several years, why doesn't it blossom?

Magnolia is one of the flowers and plants that many friends like, and it is also quite common in the market. I would like to share it with you today.

Gentleman orchids usually bloom in three or four years, and can blossom in two and a half years when they grow well. But some flower friends have raised magnolia for 5 to 7 years. That is, it does not blossom; or after blooming for a year, it never blossoms again, even if it blossoms, there are very few flowers. What is the reason for this?

The main results are as follows: 1. The sunshine in summer is too strong, the time in the sun is too long, and the leaves are in high temperature, which consumes a lot of nutrients, and the leaves turn yellow and brown, which is disadvantageous to the budding and flowering in autumn. In summer, in addition to strengthening ventilation, but also shade, to avoid direct sunlight.

2. Excessive application of nitrogen fertilizer and lack of phosphorus fertilizer. Nitrogen fertilizer is mainly long leaves, too much nitrogen fertilizer during flowering, the leaves are green and green, nutrients are still concentrated on vegetative growth, and it is difficult to divert arrows without differentiation of flower buds. From September to mid-October, the application rate of nitrogen fertilizer was reduced and the amount of phosphorus fertilizer was increased.

Phosphorus is involved in the formation of anthocyanins, which can promote flower bud differentiation, early bud cultivation, arrow channeling and flowering.

3. In winter, the indoor temperature is too low, lower than 10 ℃, the photosynthesis is weak, the growth is inhibited, and the scape can not be extracted. The temperature is kept at 18 ℃ 20 ℃ during the day and no less than 8 ℃ at night, which is beneficial to arrow channeling.

4. Put the orchid on the shady side for a long time, the sunlight is insufficient, the leaves are thin and yellow, which affects the photosynthesis.

To sum up: the room temperature of Cymbidium in winter should not be less than 15 ℃ in daytime and 8 ℃ at night. Summer should be placed in a slightly shaded place, not in direct sunlight. Give appropriate phosphate fertilizer after September, such as fermented fishbone water, ammonium phosphate and so on.

Gentleman orchid has been raised for several years, why not blossom to share with you here, I believe we all have a certain understanding, I hope this article will be helpful to you, good luck.
