There are five main reasons why Manjusri does not blossom:

1. Light

The lack of light, affecting photosynthesis, organic matter accumulation is insufficient, can not form flower bud differentiation, so do not flower. Although the orchid is more tolerant to shade, it is too shaded, and the accumulation of organic matter is too slow and too little, resulting in insufficient nutrition (energy) or imbalance in the body, so it does not form flower buds and has no flowers to bloom. In the future management, to give reasonable sunlight, sufficient light, organic matter (carbohydrates) accumulation, easy to form flower buds. The method adopted is: in addition to preventing exposure in June, July and August of each year (in the north), full sunlight should be given. Sunlight is too strong, not exposure, exposure will burn the leaves, leaves yellow and dry, very ugly, affecting the ornamental value. After the orchid leaves the room, in the northern region, it can be kept on the balcony facing north, where you can see direct sunlight in the morning and evening. Crucifera can withstand high temperatures of 35℃~37℃ in midsummer. High temperature does not affect its growth, but is beneficial to flower bud differentiation.

2. Nutrients

Not enough nutrients, lack of fertilizer. fertilizer shortage, the phenomenon of slow growth will occur, leaves become thin, no strength flowering. In the future, more nitrogen, phosphorus and potassium compound fertilizers should be applied appropriately. Compound fertilizer nutrition is more comprehensive, conducive to nutritional growth and reproductive growth, flowering is beneficial. Do not apply a single fertilizer, so as not to cause deficiency, incomplete elements are not easy to form flower bud differentiation, so the probability of flowering is less. Don't neglect to use nitrogen fertilizer, too. When nitrogen is insufficient, the fragrance of flowers will fade. Fertilization should be in the growing season, the use of organic fertilizer should be once every half month, the use of chemical fertilizer should be once every ten days, can also add foliar fertilizer. Fertilization should pay attention to the right amount, depending on the size of the seedlings, see the specifications of the pot, not excessive. You don't have to apply base fertilizer, but you can apply topdressing. Fertilizer acid, alkalinity can not be considered, because the ability of the north of the Crucifera alkaline fertilizer and alkaline water, it grows well in the north cultivation.

3. Moisture

Crucian orchids are more drought-tolerant flowers, but they are also more moisture-tolerant. The plant material in the flowerpot in the case of no ponding, to the growing season to appropriate more water, can be poured once a day permeable water. Summer weather is hot, water evaporation is large, plant metabolism is fast, water demand is large, this season is not dehydrated. If the soil in the basin is dehydrated and the drought is too large, it will be unfavorable for the flowering of Crucifera.

4. Basin soil

The soil in the pot needs to be changed once a year. This is because the orchid has the habit of tilling and bearing seed plants. A large number of young plants (seedlings) are produced annually at the base of the stem, ranging from 5 or 6 seedlings to more than 10 seedlings, sometimes more. If you are not ready to reproduce, you should change the soil before leaving the room in spring every year, and break off the tillers one by one in time. Do not leave a seedling. This is to reduce the consumption of nutrients, reduce the burden on the mother plant, and effectively accumulate the organic matter of the mother plant. This is beneficial to flowering. When you change the soil for a plant, you don't have to worry about damaging the root system. You often break one root system, and it will regenerate many new roots. Instead, the roots grow more vigorously.

5. Flower pots

Crucifera grows vigorously and has developed root system, so it should pay attention to using larger flowerpots when cultivating. Generally, seedlings more than three years old should be replaced by large pots with an inner diameter of 25cm to 35cm. Pot large soil, roots can be unlimited extension, conducive to the absorption of water and nutrients, can meet the needs of plant growth.

What if they don't have a flower?

Have you ever heard of the orchids? Crucifera is a beautiful ornamental plant, whether it is planted as a courtyard, or indoor potted culture, are very good, but in the breeding process encountered Crucifera does not bloom how to do it? How long is the flowering period of the orchid? Let's take a look at the answers below.

What to do if the orchid does not bloom?

There are usually three reasons for the failure of flowering: one is insufficient light; the other is insufficient nutrients; and the third is insufficient water. All in all, there is not enough conditions for the flowering of Crucifera.

1) Lack of light. Light affects photosynthesis and accumulates organic matter. Without enough organic matter synthesized, flower bud differentiation cannot be formed, so flowers do not bloom. All sunlight should be given to the orchids except in the summer of each year. Although Crucifera can withstand high temperature of 35℃ (and high temperature is conducive to flower bud differentiation), direct sunlight will burn the leaves, causing the leaves to turn yellow and dry, thus affecting the viewing effect.

2. Insufficient fertilizer. Lack of fertilizer, the phenomenon of slow growth will appear, leaves become thin, no strength to flower. The rescue method is: appropriate multi-application of nitrogen, phosphorus, potassium compound fertilizer. Compound fertilizer nutrition is more comprehensive, conducive to nutritional growth and reproductive growth, beneficial to flowering. Application of single fertilizer is easy to cause element deficiency, and incomplete elements are not easy to form flower buds.

3. Insufficient water. In hot summer, the water loss of Crucifera is rapid, the plant metabolism is fast, and the demand for water is large. If the drought time in the basin is long, it is unfavorable for the flowering of Crucifera. Under the premise of no ponding in the basin, it is necessary to pour more water in the growing season, and it can be poured once a day.

The flowering of the orchid:

The flowering period of Crucifera is generally from May to August, but if the growth environment and temperature are appropriate and the maintenance method is appropriate, flowers can be produced every month. The flower language of Wenxian orchid is: walk with you, love of husband and wife. These flowers are suitable for lovers.

More information on the causes and solutions of yellow leaves of Crucifera, and the solution to rotten roots

Crucifera is one of the common flowers in our family. They have beautiful flowers with a faint fragrance and green leaves. Crucifera is a kind of flower with high ornamental value. It is very beautiful when it is in full bloom. It also has yellow leaves and rotting roots. Today, I will bring you together to understand.

Causes of yellow leaves

1. Too little watering causes the soil to be too dry and airtight, so that the leaves dry up.

2. Too much watering leads to rotten roots, roots unable to absorb water, and leaves withered.

solutions

1. Crucifera likes warm and humid areas, slightly resistant to cold, but not cold-resistant. The temperature suitable for growth is 15-20℃. During its growth period, it needs a lot of fertilization and watering, especially before and after flowering and during flowering. Adequate water and fertilizer are needed every day.

2. If the leaves of Crucifera are too long, it will lead to its top-heavy weight and lack of nutrients. At this time, it is necessary to replace the pot soil and change it to a larger pot, so that its roots have more sufficient space to collect water, so that they will thrive and grow green.

The way to judge rotten roots

1. Basin soil

Flowers and trees that can grow normally in summer and autumn are watered once a day. If the pot soil is dry, it will behave normally. If it is in a wet state, it has rotted roots. If the pot soil is still wet without watering for a few days, most of the roots have rotted.

2. leaf color

If there are several pots of flowers of the same kind, one pot is found to have lost its luster or wilted when placed together, indicating that root rot has occurred.

3. leaf shape

The leaves are wrinkled and deformed, indicating that the roots have rotted, and the leaves have become gradually withered due to lack of water and nutrients due to decay.

solution

If the root of the orchid rotten is not easy to cure, pull the flower out of the pot, quickly cut off the rotten part of the root, disinfect it with potassium permanganate, and plant it again in the pot. If only a small amount of rot, then you can use the above method, wait about three days to replant and normal maintenance. In its growth period must maintain sufficient water and fertilizer, do not diligently watering, excessive fertilization.

The above is the relevant knowledge of the yellowing and rotten roots of the orchid leaves I sorted out. I hope it can help the majority of flower friends. Please also continue to pay attention to the fleshy flower beds and learn more about flower maintenance.
