Tuberose tuber bulbs are planted for many years and do not bloom, why

Tuberose flower stems are slender, the lines are soft, it has a certain ornamental value, and its flower color is white and fragrant, so some people will choose to plant it in the courtyard, one of the most common problems in tuberose cultivation is not flowering, and the following will take you to understand the reasons why tuberose does not bloom: Reasons why tuberose does not bloom Look which one you are guilty of Tuberose not flowering Reasons why tuberose does not bloom: 1. Improper storage If the tuberose tuber is not stored properly in winter, it will be wet and frozen, resulting in frost damage or rot of the main flower buds in the tuber. In this way, it will not be able to bloom in the next year, although there are secondary flower buds in the tuber, but due to the short growth period, it will not have time to pull out before the frost period has arrived.

Therefore, if you want tuberose to bloom, you should fully dry the skin of the tuber and store it in a dry and warm place to prevent the main flower buds from rotting, and it should also be planted as early as possible and harvested late. 2. Digging the ball too early Digging the ball too early is also the reason why tuberose does not bloom, because digging the ball too early affects the formation of flower buds in the tuber, resulting in the second year can not bloom, so in the case of not suffering frost damage, try to dig the ball as late as possible, which is one of the measures to improve the flowering rate of tuberose. 3. The planting tuber is too small Generally, the diameter of the tuberose tuber should be long to more than that, and the flower buds can be formed and flowered internally, if the planted tuberose is a small tuber, less than 2 cm, and the tuberose will not bloom if it has not reached the flowering age.

Therefore, in order to promote the flowering of large balls, shallow planting can be done when planting, so that the entire apical bud is exposed to the soil surface; In order to promote the growth of the small ball, it should be planted deeply, and only the tips of small seedlings should be exposed after covering the soil. 4. Excessive fertilization Another main reason why tuberose only grows leaves and does not bloom is due to excessive fertilizer and water, especially the excessive amount of nitrogen fertilizer, which leads to excessive vegetative growth, that is, the stems and leaves are long, which inhibits the growth of flower buds, resulting in fewer flowers or even no flowering. Therefore, the concentration of fertilization, especially the amount of nitrogen fertilizer, should be strictly controlled during the vegetative growth period, which is an important technical measure to prevent tuberose from only growing leaves and not flowering.

Tuberose does not bloom is a problem encountered by many people when planting, which is caused by several reasons, the key is to pay attention to the tuber storage from tuberose to usual maintenance, so as not to tuberose light leaves do not bloom, then lose its ornamental value.

1. The bulbs are not large enough: they do not have the conditions for flowering.

2. Planting too deep: deep planting to raise balls, shallow planting and flowering.

3. The temperature is not enough: the flower pavilion can be extracted above 25 degrees.

TuberoseIt is bound to pill, this is the law of natural growth.

How to preserve tuberose bulbs:

In autumn, after the stems and leaves are yellowed, the bulbs are dug up, the soil is removed, and the soil is slightly dried, and then a layer of old roots and root plates are cut off with a sharp knife at the base of the bulb, so as not to hurt the original body of the roots. Then remove the excess dead leaves, keep 2 3 leaves, continue to dry and dry, the bulbs are fully dried and braided, about 10 1 strings, too much is easy to break.

The bulb braid is hung in the indoor air, and the loose balls that can not be braided are placed on the mesh board, and the fire oven is baked below, the temperature of the bulb is about 25 35, after 5 10 days, the bulb skin is dry, and the smoked ball treatment is finished, and then it is hung in the 15 20 indoor storage, and the sub-balls are separated and cultured in the spring of the following year. The large balls germinate quickly after planting, and most of them can bloom, and the above is an introduction to the preservation method of tuberose bulbs.

Tuberose cultivation method:

1. Soil. Tuberose has high requirements for it. First of all, it is required to have sufficient nutrients, and then the cohesive soil is more suitable for it, if you choose sandy soil, it will not be conducive to its growth. Specifically, peat soil can be used.

humus and river sand.

Match, in a ratio of three to two to one, and mixed with some farm manure. In addition, it is necessary to change the pot in the spring of each year, that is, around April, and repair the roots of the same brigade.

2. Temperature. The most suitable temperature for tuberose is twenty to thirty degrees. In winter, it is better to keep it indoors or in a greenhouse at a temperature of 8 to 12 degrees. If it is below five degrees, it will suffer frost damage, and if it is any lower, then it may even freeze to death.

3. Illumination. When it grows rapidly, it needs to be high in the air to provide good light, and place it in a place with sufficient scattered light. In winter, it is generally indoors, and the light should not be too dark, otherwise it will also affect its winter, as well as the growth of the next year.

No, the leaves are pruned for aesthetic reasons.

TuberoseScientific name: Polanthes Tuberosa L) is of the Lycoris family.

Tuberose is a perennial herbaceous plant that can reach up to 1 meter in height. The stems are erect and unbranched.

The basal leaves are clustered and branched, linear, pointed at the apex, dark green, and the leaves are scattered on the flower stems, tapering upwards and showing bracts.

Shape. Spike-like inflorescences apical, often flowering in each bract, bracts green; The flowers are milky white, fragrant, the perianth lobes are similar to each other, oblong-lanceolate, the ovary is inferior, the flower column is slender, and the capsule.

Ovoglobic, with many seeds, slightly flattened. Blooms from July to September.

Growth habits. Tuberose is an evergreen herb in its place of origin, and it grows all year round when the temperature is suitable, and blooms in all seasons, but it is most prosperous in summer; In China, however, in the open field, due to the severe cold winters in most areas, spring bulb cultivation can only be used: budding growth in spring, flowering in summer and autumn, and dormancy in winter (forced limb sleep).

Tuberose is self-pollinating, but because the pistils mature later than the stamens, the natural seed setting rate is low.

Tuberose prefers a warm, humid and sunny environment, and grows at a temperature of 20-30. The requirements for soil quality are not strict, and clay loam soil is appropriate; It is sensitive to soil moisture and prefers fertile, moist but not waterlogged soil.

TuberoseIt blooms only once a year. The flowering period is from July to November every year, and the flowering period is from August to September.

The flower color is elegant and white, and the fragrance is very strong at night. Tuberose blooms in four seasons in its place of origin, and when cultivated in our country, it blooms in summer and autumn and dormants in winter due to the cold winter in most areas.

Tuberose only blooms once a year and only blooms in summer or autumn. When planting, you can ensure more flowering period and pay more attention to light, so that the flowers will bloom a little more.

It will only bloom once a year, and then the flowering time is between July and November, pay attention to the intensity of the sun, the temperature should be controlled at about 28 degrees, and it is necessary to strengthen the seedling work of seeds, be sure to prune the branches and leaves in time, and be sure to fertilize properly.

Tuberose blooms once a year, and when planting, if you want to bloom more, you should ensure that the sun is sufficient.

The reason why tuberose only grows leaves and does not bloom.

The plants are not of flowering age.

The flower buds of tuberose are already formed on the bulb a year before planting. It may be that the plant is too small and has not yet reached flowering age, so it does not bloom.

The bulb was dug at the wrong time.

The bulb is dug too early, and the tuber has not yet budded, so after planting, only leaves grow and do not bloom. Digging the bulb too late will also cause tuberose to only produce leaves and not bloom. In winter, the temperature is too low, and the tuber freezes in the soil, so that the flower buds in the tuber are also frozen, and may even rot.

This condition can also cause tuberose to grow leaves and not to bloom.

Improper storage of bulbs in winter.

Improper storage of tubers in winter, such as drying the bulbs in a dry cellar and burying them with straw and soil, can also lead to less flowering.

Excessive fertilization. Excessive application of nitrogen fertilizer after planting caused the stems and leaves of tuberose to grow too fast. This condition will cause tuberose to bloom less, or even not at all.

What to do if tuberose only grows leaves and does not bloom.

Choose excellent varieties to make traces.

When choosing tuberose, it is necessary to plant tubers that are relatively large and healthy.

Reasonable storage in winter.

In winter, the hail tubers should be stored at room temperature of 25-26 to gradually reduce the moisture in the bulbs until the outer skin is dry and wrinkled, and then the temperature is 15-20 until the following spring. Store the tubers in winter, or you can choose to hang them indoors and bake them over the fire. After roasting, the tubers can be relatively dry, forcing the tuberose tubers into a dormant period, which is conducive to growth and flower bud differentiation after planting in the following spring.

Proper fertilization. Fertilize less at the beginning of planting, wait until the flower stems are about to be pulled out or before flowering, and top dressing should also be available. Generally, it is applied once a month after planting, once before flowering, and once after a month and a half or two months.

Tuberose can be used to decorate the environment or to plant potted plants. Then, if tuberose is kept at home as a potted orange, it can also decorate the indoor environment. If tuberose does not bloom, there will be less mood for cultivation.

Xiaoyisou summarized two reasons why tuberose does not bloom for everyone. Reasons why tuberose does not bloom:1.

Improper storageIf tuberose is not stored properly during the winter months, it can be affected by moisture and cold, causing the main flower buds in the tuber to freeze or rot, so that they cannot bloom when planted the following year. Although the tubers have attached flower buds, they will reach the frost period due to the short growth period. Therefore, in order for tuberose to bloom, the tubers should be sufficiently dry and stored in a dry and warm place to prevent the main flower buds from becoming moldy, and tuberose should be planted early and harvested late.

2.Harvesting too early is also the reason why tuberose does not bloom. Because digging too early affects the formation of flower buds on the tuber, it will not be able to bloom the next year.

Because Fan Wu knew this, digging the ball as late as possible was one of the measures to improve the flowering rate of tuberose without suffering frost damage. 3.Planting tubers is too small.

Generally, tuberose's tubers need to grow above the diameter in order to form flower buds and bloom in the internal state. If the planted tuberose is a small tuber, less than 2 cm, and has not reached flowering age, tuberose will not bloom. Therefore, in order to promote the flowering of large balls, shallow planting can be done so that the entire terminal bud is exposed to the soil surface; In order to increase the size of the balls, plant them deeply, and only the tips of the seedlings are exposed after covering with soil.

4.Another major reason for excessive fertilization is that tuberose leaves only grow and do not flower, because too much fertilizer and water, especially nitrogen fertilizer, leads to overgrowth of nutrients, that is, excessive growth of stems and leaves, inhibiting the growth of flower buds, resulting in fewer flowers or even no flowering. Therefore, the concentration of fertilizer, especially the amount of nitrogen fertilizer, should be strictly controlled during the vegetative growth period, which is an important technical measure to prevent tuberose from only growing leaves and not flowering.

It is a problem that many people encounter when planting tuberose. There are several reasons for this. The key is to pay attention to the tuber storage and maintenance of tuberose, so that if the tuberose leaves are bright and do not bloom, it will lose its ornamental value.
