Why gardenia leaves don t grow anymore

Gardenias prefer warm, moist and light.

If the fertilizer is too heavy, change the pot.

Put the gardenia in a well-lit but not direct sun, if you are willing, you can cut off the original branches, keep 10cm in height, and wait for the new branches to grow again, and the new branches will be more perfect. If you are reluctant, you can also keep the potting soil loose and moist, but not too wet. Foliar sprays can be sprayed twice a day.

New branches and leaves should grow in a month or so.

Gardenia cultivation techniques:

Likes sour soil. The alkali content of soil, water and fertilizer makes the plants unable to absorb iron, and affects the formation of chlorophyll, causing branches to wither, leaves to scorch, and even death. Use fertile, loose, well-drained acidic soil, such as mixing pine sawdust into the soil, the effect is also very good.

Likes shade. Do not be exposed to the scorching sun, but often some people mistakenly think that gardenias require full shade, so as to cause mistakes in cultivation, in fact, pay attention to the cultivation of its cool environment at the same time, to maintain 60% of the light throughout the day, in order to meet the needs of its growth.

In the Northeast gardenia, the first thing to pay attention to is that the optimal growth temperature of gardenia is 16-18. The temperature in the Northeast is low in winter, often below 0, so in winter in the sunshine, the temperature is not lower than 0, let it sleep (but not next to the heating), too high temperature will affect the next year's flowering. In summer, gardenias should be maintained in a sparse forest or shade shed with good ventilation, high air humidity and light transmission.

Gardenias are shade-tolerant, but they cannot be completely shaded or exposed to the sun, so they should be placed in a place where they can receive sunlight in the morning and evening and avoid the harsh summer days at noon. In winter, it is placed in front of the sunny window.

Gardenia leaves wilt, 2 reasons to solve in time, stall troubles.

Gardenia leaves wilt, 2 reasons to solve in time, stall troubles.

Is there no leaves, or is there no new leaves? Send a ** to come and see.

Gardenias only grow leaves and do not bloom may be due to: too much nitrogen, too high temperatures, lack of light, construction problems, or pests and diseases.

1. Too much nitrogen fertilizer

Gardenia normal growth and smooth flowering are inseparable from the application of water and fertilizer, if only the leaves do not bloom, it may be because this aspect is wrong. It may be because of too much nitrogen fertilizer, which makes the plants grow too long, but the lack of phosphate and potassium fertilizers makes it difficult for flowers to grow. Fertilization can be applied normally before and after the flowering period to reduce nitrogen and increase phosphorus and potassium.

Second, the temperature is too high

During winter maintenance, the indoor temperature is too high to cause it to germinate early, so that it is difficult to form flower buds, and it is difficult to grow flower buds, let alone flower. If the indoor temperature is too high, you can move it to the balcony.

3. Lack of light

Flowering has a lot to do with the replenishment of sunlight, if there is not enough light, it is difficult for the plant to flower. According to the change of seasons, give appropriate sunlight, pay attention to shade in summer, avoid the sun, and supplement the sun in winter to contact the full sun.

Fourth, the problem of pruning

Not pruning for a long time is also one of the reasons, the branches grow long and heterogeneous, consuming too many nutrients, so there is no way to concentrate nutrients to promote flowering. It can be pruned regularly to remove part of the branches.

5. Pests and diseases

If the plant is left unventilated for a long time, the plant may be infected with pests and diseases, which can also affect the growth of flowers. Ventilation can be used for prevention, and if pests and diseases are found, spraying in time**.

Gardenias only have leaves and may be pruned regularly due to poor pruning; It may also be due to the poor fertilization ratio, more phosphorus fertilizer should be used to increase flower bud differentiation; It may also be due to excessive water, during the pregnancy bud period, it is necessary to reduce the water; In addition, it may be that the sleep temperature is too low, so it is necessary to keep the sleep temperature above 5.

1. Pruning problems.

1) Specific reasons: Some plants will grow very lushly. If you don't prune for a long time, nutrients will be supplied to the stems and leaves, and the growth of flower buds will be hindered.

2) Solution: It is best to prune the plant regularly, and it is definitely not possible to prune it for a long time.

2. Fertilizer problems.

1) Specific reasons: The main reason is that the type of fertilizer is wrong. Specifically, there is too much fertilizer containing N, which causes the leaves to grow quickly.

However, if there is too little fertilizer containing P, the flowers will not bloom. As a result, the plant appears to be vigorous, but in fact it is only leaves and no flowers. Ming Travel Respectfully.

2) Solution: Phosphate fertilizer is of great significance for flowers. Especially when the flower buds begin to differentiate, we must use more phosphorus fertilizer and less nitrogen. For example, (Kh2SO2) solution, etc.

3. Moisture problem.

1) Specific reason: Before the flower buds are bred, if you water too much, the leaves of the plant will grow very quickly, but the flowers will grow less.

2) Solution: During the pregnancy bud period, reduce some water appropriately.

4. Temperature problem.

1) Specific reasons: This mainly refers to the temperature is too high in winter when the plant is dormant excitonator. In this way, the dormancy of the plant will be broken prematurely, and then the buds and leaves will be sent out prematurely, consuming a lot of nutrients. When it's time to bloom, the number of flowers is small.

2) Solution: The temperature during dormancy is best around five degrees, so as to survive the winter safely.

1. Single fertilization: The single use of nitrogen fertilizer leads to the growth of gardenia branches and leaves, and phosphorus and potassium fertilizers should be applied to promote the differentiation of flower buds.

2. Too little pruning: the permeability between the plants is affected by the construction of the plant, and the dense branches and long branches should be pruned frequently.

3. Insufficient light: long-term exposure to low light environment leads to weak plant growth, so 6 hours of light should be provided every day.

fruit ovate, nearly spherical, elliptic or oblong, yellow or orange-red, long centimeters, centimeters in diameter, winged longitudinal ridges 5-9, top sepals up to 4 cm long and up to 6 mm wide; The seeds are numerous, flat, nearly rounded and slightly angular, about mm long and about 3 mm wide. The flowering period is from March to July, and the fruiting period is from May to February of the following year.

If the humidity of the humid air is lower than 70%, it will directly affect the differentiation of flower buds and the growth of flower buds, but too humidity will cause root rot and branch withering, and leaf yellow falling off. In addition to normal watering, the foliage and nearby ground should be sprayed with water frequently to increase the air humidity.

Fertilizer-loving should be applied to cooked soybean cake, sesame sauce residue, peanut bran and other fertilizers, fermentation and rotting can be acidic, but must be thin fertilizer more application, avoid thick fertilizer, raw fertilizer, hibernation period without fertilization. If it has been planted for less than three years, it is important not to apply human feces. Excessive nitrogen fertilization will result in thick branches, large leaves, and thick green, but no flowering.

When phosphorus and potassium fertilizers are deficient, there will also be no flowering or flower buds wilting and falling off.

The thermophilic growing period is 18 22, the overwintering period is 5 10, and the temperature is less than -10.

Trim at the right time. Gardenias form flower buds in April, so in April and May, in addition to cutting off individual redundant branches and leaves, it is generally important to protect the buds; When the new shoots grow to 2-3 nodes, the first topping should be carried out, and part of the axillary buds should be appropriately erased; In August, the second stubble is topped and the canopy is cultivated, and the plant with a beautiful tree shape can be obtained. Gardenia requires good growth in acidic soil with soil pH 5-6, and in neutral or alkaline soil in the north, it should be watered with alum fertilizer water or foliar spraying with ferrous sulfate solution at the appropriate time

There is no time to flower. Gardenias bloom in different seasons and at different times, and gardenias do not grow to this age of flowering, they will not bloom.

Gardenias only grow leaves and do not bloom due to improper fertilization, lack of pruning and overwatering.

Improper fertilization

In the process of maintenance, improper fertilization of gardenia can easily cause it to only grow leaves and not bloom. In particular, if nitrogen fertilizer is applied too much, it is very difficult for gardenias to bloom in the absence of other fertilizer components. Generally speaking, nitrogen fertilizer promotes the growth and development of branches and leaves, while phosphorus and potassium fertilizer promotes strong plant growth and vigorous flowering.

Many flower friends in the maintenance, the fertilization is too single, and the nitrogen fertilizer is too much, which leads to gardenias only grow leaves and do not bloom.

Workaround:If your gardenia branches and leaves are lush and slender, and you are slow to bloom, it is necessary to reflect on our fertilization methods, if you want to make gardenia bloom vigorously, pay attention to nitrogen fertilizer during the growth period, and start to apply phosphorus and potassium fertilizer one month before the flowering period to promote flower bud differentiation and make it bloom continuously.

There is no pruning

Gardenia leaves are emerald green, the branches and leaves are luxuriant and vigorous, in the maintenance process, with the continuous growth of the plant, its branches and leaves will grow more and more luxuriant, when the branches and leaves are too luxuriant, the ventilation and light transmittance of the plant will be affected, and the gardenia plant is more light-loving, and it is difficult to bloom if the light is insufficient, so we should pay attention to regular pruning to it.

Workaround:When the gardenia grows too densely, cut off some leaves in moderation, which can increase the light transmission and ventilation of the whole plant. Flower picking is to cut off the flowers in time after they have withered, so as not to consume more nutrients.

When autumn is approaching, don't prune him, increase phosphorus and potassium fertilizer. Give him plenty of light, and the buds will naturally come out and bloom.

Overwatering

Gardenias are afraid of drought and like moisture, many flower friends in order to promote its healthy growth, will be late to shoot more watering, but before giving birth to flower buds, if you water too much, it will also make the leaves of the plant grow very fast, but the flowers grow less.

Workaround:When watering gardenias, you should pay attention not to dry and water, and to water thoroughly. When the soil surface is white, pour it until a small amount of water flows out at the bottom of the pot.

Generally speaking, it is dry and watered, gardenias are afraid of drought and like moisture, but in the bud period, reduce some water appropriately. It controls the growth of its branches and leaves, and promotes the flowering of plants.

1. Gardenia wilting is a lack of water 2, the leaves are yellow and less watered 3, the old does not bloom is less light 4, the glue soil must be replaced 5, the flower buds can not be wet 6, the new leaves are white and iron lack fertilizer 7, the leaves are yellow and less fertilized

The gardenias bought in the flower shop basically have a lot of buds, and they are ready to be put one by one, and it seems that you can get a pot of fragrant gardenias when you buy it home, but! This is not the case!

Gardenia does not bloom reasons

1. Lack of light

Gardenias placed in a shaded environment for a long time will affect the differentiation of flower buds, resulting in non-flowering. It needs more sunlight (more direct light, not scattered light through glass), and only when the demand for light is met can gardenias bloom.

2. Lack of nutrients

Gardenias are fertilizer-loving plants, especially before and after flowering, and need to be fertilized regularly. It is recommended to apply phosphorus and potassium fertilizer (flower type) before flowering, mix it with water in proportion, and spray the leaves and then irrigate the roots once a week in the morning or evening when avoiding sun exposure.

3. The soil is unsuitable

Gardenias prefer slightly acidic soil environments, and if the soil used is too alkaline, it will affect growth and flowering. When planting, it is necessary to choose loose and breathable acidic nutrient soil.

If it has been planted, the soil acidity and alkalinity can be adjusted by applying ferrous sulfate or acid-loving plant liquid fertilizer in the later stage.
