Can the big flower Whelan still bloom after the flower has fallen?

If it's an individual, it shouldn't be normal!

After flowering, the flower stalk needs to be pruned off in time to avoid the consumption of nutrients, and the potassium dihydrogen phosphate fertilizer is applied once to supplement the nutrients for the plant.

1. Prune the flower stalks

If you want to collect seeds, you can wait for the large-flowered Huilan to complete the collection and then prune, and at the same time prune the withered leaves.

2. Top dressing fertilizer

After flowering, the nutrients of the plant itself have been greatly lacking, at this time, it is necessary to apply a phosphorus and potassium fertilizer in time to supplement nutrients for the plant, potassium dihydrogen phosphate is the most common on the market, and it can be diluted with watering after fertilization to promote the absorption and utilization of nutrients by the root system.

3. Increase lighting

Whelana is a light-loving plant, after flowering, it needs to be moved into a light astigmatism environment to promote photosynthesis, if no light is given for a long time, the leaves of Whelan will appear yellow, which is not conducive to the growth of the plant, so it is best to maintain 8 hours of light every day.

4. The moisture is reasonable

Breeding large-flowered Huilan must be watered reasonably, need to follow the principle of not drying in autumn and not wet in winter, so as to avoid the phenomenon of rotten roots, if the air is too dry, increase the humidity environment by spraying clean water, promote the growth of large-flowered Huilan, and make it quickly resume growth.

It will grow, but you have to find the reason. If you don't find the reason, you'll die.

Large-flowered orchid, an evergreen plant, has become the first choice for many people who like orchids because of its gorgeous flowers and easy to cultivate. However, although it is relatively easy to raise, there are also some breeding matters that need to be paid attention to, so that the survival rate of Acacia grandiflora is high and the flowers are flourishing. ”

Large-flowered orchid entry, evergreen plant, because of its gorgeous flowering and easy to cultivate, has become the first choice for many people who like orchids and bright plants. However, although it is easier to raise, there are also some breeding matters that need to be paid attention to, so that the survival rate of the large-flowered orchid is high and the flowers are flourishing.

Difficulties in the cultivation of Cymbidium grandiflora.

The roots of the large-flowered orchid are sensitive to water and are either "drowned" or "dyed of thirst". When the over-wet or over-dry state of the planting material lasts longer than the langen can tolerate (to be exact, the anoxic or dehydrated state of the planting material lasts longer than the langen can tolerate), it will cause root rot or empty roots; If it lasts longer, the root problems will be reflected in the leaves, and the plant will eventually wither and die.

1. The large-flowered orchid is watered too much and the roots are rotten.

Because the pseudobulb entry of C. grandiflora itself contains water, and whether the root is rotten or empty, the residual part of the root still has a trace of water absorption function, so even if there is a problem with the lead key of the root of Cymbidium grandiflora, it can still survive for a period of time, and it is not easy to find the problem in time from the aboveground part of the plant.

In fact, the large-flowered orchid is more likely to be "drowned", that is, due to improper selection of planting materials, too strong water retention or excessive watering, resulting in the planting material is always wet. When this state of overwetness lasts longer than the tolerable limit of the large-flowered orchid, the orchid root rots and the orchid eventually dies. In addition, some people have heard that the large-flowered orchid is "afraid" of water, so they rarely water it, and the result is overkill, and the large-flowered orchid is "thirsty to death", and there are also cases of this situation.

It can be seen that whether the water content in the planting material can be controlled is the key to the success or failure of orchid cultivation.

Still. Here's how:

1. Prune. Many flowers need to be pruned after flowering to concentrate nutrients for plant growth, and Cymbidium grandiflora is no exception, so cut off the flower stem in time and apply carbendazim to the wound to prevent bacterial infection and affect the normal growth of the plant.

2. Change the pot. The root system of the large-flowered orchid is well developed and very stout, and it needs to be repotted after flowering. When repotting, first remove the soil from the root system, then cut all the roots short, leave them 10-15 cm long, and then carefully check the root system for rot.

If there is a rotten root system, be sure to cut it off, and don't be soft. After pruning the root system, prepare a pot of water, pour carbendazim and rooting agent, melt it, put in the large-flowered orchid, soak the root system for 10-15 minutes, and then pot.

The natural flowering period of the large-flowered orchid is generally from October to April of the following year; Now, it has been discovered that artificially controlling the temperature difference between day and night during the flower bud differentiation period allows it to open at the right time.

It blooms from February to March when the temperature is 10-25 degrees Celsius, and is delayed until April-May below 5 degrees.

Cymbidium grandiflora is a variety that is not easy to reflower, and the reason why it is not easy to reflower is because it has high requirements for growth (flowering) conditions;

The following is a summary of my experience in raising orchids in the past 8 years.

1. There should be sufficient nutrients for it to grow.

2. The ambient humidity is required to be 70-80%, the shade is 60-80% (double-layer sunshade net), and the temperature is 16-28 degrees.

3. The most important one is that the temperature difference between day and night should be at least 10 degrees or more.

4. In winter, there should be a low temperature of at least 2-5 degrees for more than a month to facilitate vernalization.

If the above conditions can be met, it is guaranteed to bloom every year, and it will bloom more and more every year, and it will bloom well.

The flowers are purchased by flower sellers from other places, and the large-flowered orchid has been commercially cold-treated. The book says that the temperature of the large-flowered orchid in autumn or winter should be below 5 degrees for the flower buds to germinate normally; If you have the right temperature, not flowering is also related to nutrients.

It is native to the southwest of China. It is often wild in the semi-shady environment of the edge of the ravine and the understory. Prefer warm winters and cool summers.

The growth temperature is 15 25. It is better to have a temperature greater than 10 at night. The leaves are green, the flower buds grow and develop normally, the flower stems elongate normally, and they bloom in February and March.

If the temperature is lower than 5, the leaves are yellow, the flower buds do not grow, the flowering period is delayed to April and May, and the flower stems are not elongated, which affects the flowering quality. If the temperature is around 15, the flower buds will suddenly elongate and bloom in January and February, and the flower stems will be soft and cannot stand upright. If the night temperature is as high as 20, the leaf clusters will grow luxuriantly, affecting flowering, and the formation of flower buds will also wither and yellow.

In short, the formation of buds, the extraction of flower stems and the flowering of Cymbidium grandiflora require a large temperature difference between day and night.

Cymbidium grandiflora has high requirements for water quality, likes slightly acidic water, and is sensitive to calcium and magnesium ions in water. Rainwater is ideal. During the growing season, high air humidity is required, if the humidity is too low, the plant growth is stunted, the root growth is slow and small, the leaves become thicker and narrower, and the leaf color is yellowish.

In general, the large-flowered orchid is afraid of dry and not afraid of wet.

Light is an important factor affecting the growth and flowering of Cymbidium grandiflora. Cymbidium grandiflora is a light-loving type of orchid plants, and sufficient light is conducive to leaf growth and flower bud differentiation. Too much shade, the leaves are slender and thin, cannot stand upright, the false bulb becomes smaller, it is easy to get sick, and it affects flowering.

Shading 50 60 in midsummer, and more sunlight in autumn, which is conducive to the formation and differentiation of flower buds. Winter rain and snow, such as the addition of auxiliary light, is extremely beneficial for flowering.
