Why don t my downhill orchids bloom in spring?

Most orchids are scented, some individual varieties have a faint floral fragrance that can barely be smelled, and some varieties have a light but refreshing fragrance and an endless aftertaste! Therefore, some flower friends will smell the fragrance and look for orchids, and some flower friends look forward to the blooming of orchids just to smell the orchid.

Why do we sometimes raise orchids that don't smell good? Or less flowering and less flowering? In addition to being related to the variety, it is also very related to conservation. In terms of maintenance, the main reasons for the light fragrance, less flowering and small flowering of orchids are as follows:

1. The temperature is too high.

Most orchid varieties are relatively hardy and prefer a cool growing environment, and orchids that have undergone low temperature experience tend to be a little fragrant and have larger flowers. Some low-temperature vernalization varieties have higher temperature requirements, and when the ambient temperature is too high or there is no temperature difference, it is not easy to bloom or the flowering quality will be greatly reduced. Even for varieties that do not require low-temperature vernalization, there will be a difference in the quality of the flowers that bloom at a lower temperature during the flower bud growth period and a higher temperature.

The ambient temperature of most orchid flower buds growth and flowering is best kept between 10 and 20 degrees, the temperature is too high, the flower buds grow quickly, and the flowers can open in a short time, but the appearance and floral fragrance are greatly reduced. Orchids in the bud growth period and flowering period, the ambient temperature should have a temperature difference of about 10 degrees, the highest temperature difference should not exceed 15 degrees, the flower fragrance and flower color will be better than the temperature difference is small or there is no temperature difference in the environment of the orchid.

2. Insufficient fertilization.

Whether the orchid blooms fragrantly, the number and size of the buds are all related to the fertilization in the early stage. Phosphate fertilizer tube flowers and fruits, from the beginning of orchid flower bud differentiation, it is necessary to apply a little more phosphorus and potassium fertilizer, so that the flower buds can be completely differentiated, the flower buds grow strongly, and the flowers are large and bright. Orchids with sufficient nutrient reserves before flowering should have better flower quantity and floral aroma than plants with insufficient nutrient reserves.

It should be noted that some flower friends have proposed that the orchid flower fragrance maintained by using fermented organic fertilizer will be better than that of orchids maintained by using fast-acting fertilizer, the reason is the trace elements in organic fertilizer.

It is more abundant and comprehensive, and the fertilizer effect is slow and long-lasting, which is more conducive to the growth of orchids. I think there's some truth to that, don't you think?

3. Insufficient light.

Orchids should have sufficient light during flower bud differentiation, bud growth, and flowering. Plenty of lightPhotosynthesisIt is comprehensive, can synthesize various nutrients required for growth, and the floral fragrance and flower size are relatively good after flowering. If the light is not sufficient, the flower buds are weak, the flowers are small and the color is light, and the floral fragrance will naturally not be strong.

Some flower friends raise orchids in winter or put astigmatism.

Although the leaves are green and good, they either do not bloom, or the flowering quality is low, and it is difficult to flower and leaf in unison.

In addition to that,Air qualityThe quality of orchids also has an impact on whether the orchid blooms fragrant or not, and the environment with good air circulation is stronger than the environment with poor circulation. When the orchids raised at home do not bloom fragrantly or bloom small and have few flowers, you need to find the reason in time, and you will know how to raise them well next year. Of course, everyone's judgment of floral fragrance is different, some people have a sensitive sense of smell and are easy to smell, and some people have a poor sense of smell and are easy to smell, so it is best to judge whether the fragrance of flowers is diluted to the judgment of the same variety and the same person.

The spring orchids you sent down the mountain are not fragrant. The first thing to consider is the origin and variety of this orchid. Because the orchids produced in many orchid-producing areas have no fragrance, and even have a strange taste. This is the question of the variety of the origin of the orchid, and the orchid of this variety is.

It may be the reason that there is no photosynthesis for a long time, and only regular sun exposure will have a floral fragrance.

You should be a green orchid, the fragrance of green orchid depends on the origin, the incense is strong and pure, but some places are light or not fragrant.

It is possible that the variety was purchased incorrectly. It is also possible that there is a lack of nutrients. You can try supplementing with nitrogen and potassium fertilizers. Promote the growth of plant rhizomes, so that the taste of the flowers will be more fragrant.

Undernutrition. The orchids in the mountains are usually unattended, so they are often undernourished and unable to bloom successfully.

It may be that the plant is too vigorous and secretes a lot of auxin, and auxin inhibits flowering, so the orchid only sprouts but does not bloom.

Because these flowers are not hardy to cold and are frozen, of course they can't bloom.
