Longevity flowers only grow leaves and do not bloom, why do longevity flowers not bloom and only gro

Reason: It is not heat-tolerant during flowering, and too much light or too long may cause the plant to have lush foliage but sparse buds and small flowers. If the light time is less than 4 hours, it will also cause poor growth due to insufficient light, especially in the growing season to ensure sufficient light.

Solution: Adopt the method of short day, that is, keep the daily light time at 4-8 hours, the light time during the growth period can be more than the flowering period, and the flower buds can appear about a month after short light exposure of the plants that do not bloom.

Reason: It has a long flowering period, some plants can bloom for up to 6 months, so it is a fertilizer-loving plant, if the fertility is insufficient, it may cause its flower buds to be less difficult to flower.

Solution: to ensure sufficient fertility, the general growth period fertilization to nitrogen fertilizer, after flowering can also be applied a nitrogen fertilizer, conducive to the maintenance of flowers and the growth of the next year, before the flowering can be applied nitrogen, phosphorus and potassium compound fertilizer or potassium dihydrogen phosphate aqueous solution to promote flower bud differentiation and flower blooming. However, fertilizer should not be excessive, thin fertilizer should be applied frequently, and try not to apply fertilizer on the leaves, causing leaf rot.

Reason: Apical dominance may occur if the purchased plant is not topped in time, resulting in long and slender branches and slender, and stunted lateral branches, so malnutrition makes it difficult to differentiate flower buds.

Solution: Pick the young shoots from the top 10cm of the newly bought sturdy plants or plants that have been planted to the growth stage, and new side buds will grow after a while, and the stout plants are easier to flower.

The reasons why only the leaves do not bloom are as follows:

1. Light reasons. Longevity flowers are not heat-tolerant, they like to be in cool places, and they usually pay attention to proper light in maintenance.

2. Nutritional problems: Sufficient fertilizer and water are the basis for plants to flourish, but many people often forget about this aspect, sometimes it takes a long time to apply fertilizer, and a large amount of fertilizer, and the result will be counterproductive.

It's not flowering season. The flowering period is from November to May.

Longevity flowers only grow leaves and do not bloom may be due to too long light, excessive nutrients, improper watering, etc.

1. The light is too long.

Longevity flowers prefer a shady environment, the average sunshine time can not exceed eight hours, too long the light time will make the buds smaller, difficult to bloom. In addition, it cannot be irradiated by direct light, only diffuse light. If you want the longevity flowers to bloom, you can avoid light, reduce the amount of light you spend, give six to seven hours of light a day, and put the rest of the time in the dark.

2. Excess nutrients.

Longevity flowers are not tolerant to excessive nutrients, and sufficient fertilizer and water sometimes do not lead to leafy growth. As long as the longevity flowers are placed in a bright and ventilated place, the nutrient solution is added to the pot, and when the fertilizer base material is insufficient, only potassium dihydrogen phosphate solution needs to be sprayed on the foliar surface to promote flowering. Too much nutrients can cause it to be biased towards vegetative growth.

3. Improper watering.

Watering too little will cause flower buds to not form, and too much watering will lead to stagnant water and rotten roots, so be sure to master the growth law of longevity flowers watering. Watering should not be too frequent, too much water will promote the growth of leaves, and too lush leaves will affect flowering. Generally, watering once every three to four days is enough for the growth of longevity flowers.

The growth habit of longevity flowers

Longevity flowers are autumn bulbous greenhouse flowers, which like full sunlight, tenacious vitality, can tolerate semi-shade, and are not cold-tolerant. In July and August, the leaves are dormant, and the flower buds are differentiated at the growth point of the bulb during the dormant period, which has the physiological characteristics of autumn and winter growth, early spring flowering, and summer dormancy. Longevity flowers like light, water, fertilizer, suitable for warm, humid climatic conditions, like fertile sandy soil.

It prefers coolness in the early stage of growth, slightly hardy in the middle stage, and warm in the late stage. Therefore, it is required to have no severe cold in winter and no heat in summer, and rainy climate and environment in spring and autumn.

During the day, longevity flower pots should be placed in a sunny place with plenty of sunlight to give them plenty of light. Because plants need chlorophyll to provide nutrients through photosynthesis, so that the leaves of longevity flowers can be wide and straight, the leaf color is bright green, and the fragrance of flowers is tangy. On the contrary, the leaves are tall and thin, weak, and the leaf color is yellow, or even does not bloom.

It is best to take loose and fertile, deep alluvial and empty sandy loam, and the pH is suitable for growth.

Why do longevity flowers not bloom and only grow leaves for the following reasons:

Although the longevity flower is a perennial flower, if the cultivation time is too long, it will become more and more weak, so the mother plant of the longevity flower should be re-pruned every year, pure trace or cut the young branches in front of the branch every year, and re-cutting, so that the longevity flower can grow strong and bloom luxuriantly.

If it is given too much nitrogen and not enough phosphorus and potassium, then it will grow mainly vegetatively, and the branches and leaves will grow luxuriantly, while flowering will be inhibited. Therefore, it is necessary to increase phosphorus and potassium fertilizer, which can effectively help it flower. Longevity flowers need to control light during the bud germination period.

If the light conditions do not meet the needs of the flower bud differentiation of the longevity flower, then it will also be difficult to flower.

Longevity flowers

Kalancho (Sedum succulent shrub) generally refers to Christmas cabbage (Sedum family succulent shrub), with a plant height of 10-30 cm. The stems are erect. The leaves are opposite, elliptic, with blunt teeth.

polyumbel inflorescence; The florets are orange-red to crimson. Follicles. Seed majority.

Flowering period from February to May.

The leaves are dense and green, and they bloom near Christmas, clustered in clusters, and are rich in flowers, making them a lovely indoor potted flower. The flower was introduced to Europe by the German Potsdam (R Blossfeld) from southern Africa. However, it was not until the 30s of the 20th century that Li Ru was more widely cultivated and ornamented in Europe.
