Why doesn't Gardenia blossom

Reason 1: excessive application of nitrogen fertilizer

many flower friends will apply a lot of nitrogen fertilizer to the Gardenia in order to make it grow vigorously at home, but they don't know that if the nitrogen fertilizer is applied too much, it is easy to cause the Gardenia to grow in vain, and the flower buds will not bloom without nutrients. Even if they bloom, they will fall off immediately solution: when Gardenia begins to form flower buds, more fertilizer containing phosphorus and potassium should be applied, such as 0.2% potassium dihydrogen phosphate solution or 0.5% calcium superphosphate solution, which is conducive to flower bud differentiation and bud pregnancy (author: Li Gang 104 source: Gardenia bar)

Reason 2: the soil is alkaline

Gardenia like acidic soil. If the soil is alkaline, it is easy to cause the plant yellowing of Gardenia and affect the flowering solution: 1. In order to ensure that the soil is acidic, 0.2% ferrous sulfate solution can be used to irrigate the Gardenia soil about once every half a month 2. Mix vinegar and water in the ratio of 1:30 to form a solution, and then pour it into the flower pot, which can also change the soil from alkaline to acidic (author: long month plum blossom, source: Gardenia bar)

Reason 3: no pruning plant type

if there are too many messy branches on the Gardenia plant, these branches will absorb nutrients. In this way, the nutrients supplied to the flowering of Gardenia will be reduced, which will affect the flowering; Moreover, too dense branches will also affect photosynthesis, so they will not bloom naturally solution: if you want Gardenia to blossom more, you should keep pruning. It is very important to prune both daily branches and after flowering 1. Prune diseased branches, weak branches and over dense branches. Gardenia usually blooms at the top. If there are too many useless branches, it is easy to consume nutrients and the flowers will not bloom 2. Trim after flowering. After Gardenia blossoms, the remaining flowers should be trimmed off in time. Don't just pick the flowers, you can cut them off from the second node below the flowers to reduce unnecessary nutrient consumption

Why doesn't triangle plum blossom

Reason 1: insufficient light

Prunus deltoides is a light loving plant, and the growth period requires sufficient light. If it is placed in a place where the sun cannot shine for a long time, or the light is too weak, the photosynthesis of Prunus deltoides can only be used for growth, of course, it will not bloom solution: you can put the triangle plum on the Nanyang terrace or south window sill with sufficient light. If possible, it's best to put it outdoors in a place with sufficient light. The sunnier the triangle plum is, the more it blooms (author: Google sweet source: triangle plum bar)

Reason 2: excessive watering

in order to have more flowers and long flowering period, water control treatment must be carried out before flowering. Because if you water too much, it will inhibit the differentiation of flower buds, so that triangle plum can not bloom solution: 1. If you want to make the plum blossom more, you need to carry out water control treatment. Generally, water control is carried out about three weeks before flowering. Do not water at first, let the triangle plum wither due to lack of water, and then give half of the usual water, or spray some water towards the plant to ensure that it wilts for half a day and does not wilt for half a day 2. After controlling the water for three weeks, pour water once, then loosen the soil, and apply 0.2% potassium dihydrogen phosphate solution once a week to promote the growth of flower buds. In order to concentrate the flowers and compact the plant type, 0.2 ‰ Paclobutrazol can be used once when watering is resumed (author: Diver afraid of water source: triangle plum bar)

Reason 3: the branches are not trimmed

If pruning is not done for a long time, some over dense branches on the plant will consume nutrients, and the nutrition for flowering is insufficient, so they will not bloom solution: if you want to make the plum blossom, you have to cut off some useless old branches, weak branches and sick branches on the plant, so as to reduce the consumption of nutrients before trimming: after trimming:

Why doesn't Hydrangea bloom

Reason 1: the illumination time is too long

Hydrangea belongs to short sunshine plants. If the light is more than 10 hours a day when the flower buds are differentiated, it will certainly not bloom solution: if you want Hydrangea to blossom, you should keep it in the dark for 10 hours every day during its flower bud differentiation period. Especially for Hydrangea placed indoors, you should avoid long-term light irradiation at night, otherwise it will affect flower bud differentiation (author: crusadtt source: Hydrangea bar)

Reason 2: improper fertilization

Hydrangea needs more fertilizer during the growth period, especially nitrogen fertilizer, which can promote plant growth. However, if excessive nitrogen fertilizer is applied during the flower bud differentiation period, the plant will grow in vain, the flower buds cannot differentiate, and it is impossible to blossom solution: in the flower bud differentiation stage of Hydrangea, to reduce the content of nitrogen fertilizer, apply more fertilizer containing phosphorus and potassium. You can irrigate the root with 0.2% potassium dihydrogen phosphate solution or spray it on the plant (author: xinsuixi source: Hydrangea bar)

Reason 3: improper trimming

if the vigorous Hydrangea is re cut in spring, it is difficult to form flower buds from June to August, resulting in reduced or no flowering solution: 1. Trim for the first time carry out the first pruning at the seedling stage of Hydrangea, only keep 2-3 pairs of leaves at the bottom, and cut all the leaves at the top. In about 1-2 months, the seedlings will grow 2-4 new branches 2. Pruning after flowering when Hydrangea blooms, nutrients are basically concentrated on the flowers. In order to promote the differentiation of new flower buds, cut off the remaining flowers in time. When you cut off the bottom of the flower, don't leave a pair of leaves at the same time

Why doesn't jasmine Blossom

Reason 1: insufficient light

Jasmine likes sunshine, so it is called "Jasmine that can't die in the sun". If the light is insufficient, the leaves will become smaller, the green will become lighter, the growth and development will be poor, and the flower buds will not be able to conceive, resulting in no flowering. solution: it is best to put Jasmine in the courtyard to receive sufficient light. If there is no condition, it can be placed on the Nanyang terrace or the South windowsill to let it see more sunlight, so as to promote the germination and differentiation of flower buds (author: yueyingyou bamboo source: Jasmine bar)

Reason 2: insufficient fertilizer

Jasmine in summer just enters the peak flowering period. If the fertilizer supply is insufficient, it is easy to affect the flower bud differentiation and naturally will not bloom solution: 1. Apply rotten liquid fertilizer every 3-5 days. The liquid fertilizer can be self-made bean cake fertilizer, traditional Chinese medicine residue fertilizer, etc 2. During the flowering period of the pregnant bud of jasmine, the organic fertilizer mainly containing phosphorus is applied once every three days, which can be retted with bone powder or sprayed with 0.2% potassium dihydrogen phosphate solution, which can make the jasmine bloom more and have a strong fragrance (author: Bohai yellow croaker source: Jasmine bar)

Reason 3: improper trimming

Jasmine usually needs to be pruned. Whether those branches are too dense or after flowering, they should be cut off in time to reduce nutrient consumption, so as to supplement nutrients to flower bud differentiation and promote flowering solution: 1. The flowers of jasmine only bloom at the top. Therefore, some bare branches and blind branches of jasmine should be trimmed in time, so as to make Jasmine germinate more lateral branches and open more flowers 2. Pruning after flowering after Jasmine blooms, cut off the remaining flowers, otherwise it will cause unnecessary nutrient consumption. The flowering branches can be cut off, leaving only 1-2 pairs of leaves (author: Dear Mr. Wang Xinxin source: Gardenia bar)

Why doesn't blue snow blossom

Reason 1: insufficient light

blue snowflakes like the sun. If the light is insufficient, the plants cannot carry out photosynthesis, and there will not be enough nutrients to supply the plants for flowering solution: blue snowflakes not only like sunshine, but also slightly resistant to shade. They can be placed on Nanyang terrace or Dongyang terrace and Xiyang terrace with sufficient light. Pay attention to shade at noon in summer (author: light snow on the Gold Coast source: blue snowflake bar)

Reason 2: less watering

blue snow is in the growing period in summer. If it is watered too little, it is easy to lead to poor development of plants due to lack of water, so they do not bloom solution: blue snowflakes need a lot of watering during the growth period. In summer, the evaporation is large. They can be watered once a day or two. Usually, they have to spray water around the leaves and flower pots in the morning and evening to maintain high air humidity (author: flowers bloom and snow source: blue snowflake bar)

Reason 3: no pruning after flowering

blue snow has a large amount of flowering. If it is not trimmed in time after flowering, it will lead to unnecessary nutrient consumption, so the next flowering will not know the year and month solution: after flowering, cut off the remaining flowers of Lanxue. After about 20-30 days, they can bloom again. Blue snow is not afraid of pruning. The more it is pruned, the faster it grows
