Gardenia leaves are yellow, is there a lot of water or little water or lack of fertilizer? Confused?

Gardenia flowers are as white as jade, and the fragrance is elegant and fresh, and it is an indoor potted plant that many flower friends like to keep at home. However, although gardenias are easier to bloom, there are often flower friends who report that their gardenias have yellowing leaves or even fall off. How should we maintain and manage it?

Today, Ah Yong will tell you about the three kinds of water that we need to prevent gardenia yellow leaves.

Gardenia is a typical acid-loving flower, its origin is in the south, like acidic soil, if it is a flower friend in the north to breed gardenia, long-term use of alkaline soil or alkaline water, will cause gardenia leaves to turn yellow.

If the leaves of the gardenia are yellowed due to environmental alkalinity, then it'sThe veins will remain green, but the leaves will gradually turn yellowIn this case, we need to adjust the pH of the soil, and we need to use ferrous sulfate solution or vinegar.

The frequency of use of ferrous sulfate solution can be maintained once a monthIt is best to dilute it with water more than 1000 times, and then water the gardenia, and vinegar can be used once every 15 or 20 days, the amount is not too large each time, just drop a few drops in the soil of the gardenia, but in order to fundamentally solve the problem, weYou can bury some pine needles in the soil of the gardenia, so that the soil of the gardenia can become acidic on its own.

Gardenias prefer moist soils, but if the soil moisture is too high, the root system of gardenias will be damaged, resulting in nutrient transport being blockedIn this way, the entire leaf of the gardenia, including the leaf veins, will gradually turn yellow, and even fall offAt this time, we need to protect the root system of gardenias, and the best way is to water carbendazim.

You can water some carbendazim in the potting soil of gardenia every two months to play a role in daily protection, and it can also be when gardenia has yellow leavesDepot it, remove the soil, check the root system, and prune the rotten root system thoroughly, and then water it with carbendazim solution to disinfect and sterilize.

In fact, the yellowing of gardenia leaves, in addition to the lack of nutrients caused by root damage, may also be due to our own fertilization too little, nutrient deficiency, and then cause gardenia leaves to yellow, at this time we onlyIncrease the amount and frequency of fertilization slightly, the situation can be improved.

Gardenia daily maintenance can directly use multi-element compound fertilizer, twice a month, and to the flowering period of gardenia, you can increase the frequency of fertilization, every 10 days to use potassium dihydrogen phosphate, adequate nutrition is also an important means to prevent gardenia yellow leaves.

Summary:The reasons for the yellow leaves of gardenia are generally divided into two kinds, one is soil alkaline, the other is nutrient deficiency, and nutrient deficiency can be divided into two categories, one is the root system is damaged, which leads to the obstruction of nutrient transport, and the other is the lack of nutrients in the soil itself.

The yellowing of gardenia leaves is due to lack of water and fertilizer. And it should be related to the compactness of his soil. However, under the condition of ensuring moisture and fertility, the soil can be loosened to see if it can be relieved.

The main reason for the yellowing of the leaves is that they lack potassium fertilizer, which can make the leaves produce a large amount of chlorophyll, which is conducive to light and action.

This is usually due to a lack of water or a lack of fertilizer. It's best to water it first, and if it's still yellow, we can fertilize it. When farming, we need to understand the relevant knowledge first, so that we will not be confused.

There are 3 kinds of yellowing of gardenia leaves, and only one more "water" is needed to prevent it

I know, because I've been raising this flower at home, and you can just feed him some water for washing rice.

The yellowing of gardenia leaves is mainly caused by excessive watering, hard potting soil, and lack of fertilizer. Expert.

First, the phenomenon of yellow leaves caused by excessive watering, it is not easy to be too wet when watering, and the overly wet soil is easy to accumulate water and produce root rot and yellow leaves. It is best to keep the soil dry and watered, so that it is not dry and watered, so that it is conducive to the growth of the root system, so that it is not easy to appear yellow leaves.

Second, the soil board is hard and impermeable, and the water after watering cannot penetrate into the soil layer, resulting in most of the roots being unable to absorb water and nutrients, resulting in leaf water loss and nutrient and yellow leaf symptoms. The best way is to loosen the soil properly, so that the soil is loose, breathable, drainage, and conducive to root growth.

Third, at least twice a year to apply fertilizer, 4-5 months, 8-9 months each apply a compound fertilizer, according to the amount of instructions, in order to prevent the amount of fertilizer is too heavy to produce fertilizer damage, fertilization can be with some mineral additives and other fertilizers are better. Because iron deficiency is also easy to cause yellow leaves, it is better to apply fertilizer with mineral additives, which can reduce the phenomenon of yellow leaves.

Gardenia reflowering is like a warm, moist and sunny environment, so the demand for water and the humidity of the air is also very important, during the growth of gardenia, we should pay attention to the appropriate amount of watering, but also pay attention to the gardenia foliar spray some water, can improve the humidity of the air. Put it in a cool place, gardenias must not be exposed to the scorching sun, otherwise it will cause the leaves to wither yellow, but it is not said to be placed in the full shade, because it has a certain demand for light, it is best to be placed in a place that maintains 60% of the light every day, in addition, after entering April, fertilizer should be carried out twice a month.

Too much watering, in this case, the young leaves of the mast flowers are dark yellow and dull, but the old leaves have no obvious changes, at this time, as long as the flowers are taken out of the pot and placed in a ventilated and cool place, and then put back after the soil is dry. Lack of water, leaf tips or edges withered, dry, old leaves from the bottom to the top withered yellow and fall off, but in this case the growth of new leaves is relatively normal, at this time should be watered enough, watered thoroughly.

Gardenia loves "sour water" the most, give it a cup in 30 days, the leaves are green and no longer yellow.

When making tea, the customs and habits of each place are different, we are all tea, as for the oak flower soaking in water, it is similar to tea soaking in water, too strong will turn yellow,

With the improvement of the quality of life, many people like to raise some flowers and plants at home, gardenia is everyone's favorite one, but some people are sometimes away from home on a business trip, so gardenia leaves often turn yellow.

What is the cause of yellowing of gardenia leaves.

1. Gardenias are very water-loving. During its growing season, such as spring, summer, and autumn, the soil can be kept slightly moist. Slightly damp is not moist, if it is too wet for a long time, the root system is susceptible to damage, and yellow leaves appear.

The main manifestations are yellowing of the leaves at the bottom, rotten leaves, gradually spreading to the top, and the potting soil is very moist.

2. Gardenias should have sufficient water for a long time in life, and there should be no shortage of water. Once there is a lack of water, the whole gardenia plant will wilt and be unenergetic, and the yellow leaves will fall off at the bottom. The potting soil is very dry, at this time, water it thoroughly, put it in the place where the scattered light spike is clear, let it slow down, and the new leaves can return to normal in about half a day.

3. There is a problem with the root system of gardenias, which is prone to yellowing of leaf veins and leaves that are green. Gradually spread from the bottom to the top of the plant, which means that the root system is damaged. Depot to check the root system or modify or repot, then place it in a place where the light is scattered, and let it slowly grow the roots.

The soil should be loose and breathable, and the root system should be well maintained, and then gradually receive light.

How to treat yellowing of gardenia leaves.

Gardenia will yellow leaves because after changing the pot needs to consume nutrients to root and slow the pot, and the root system wants to grow well must first consume the nutrients of the leaves, the old leaves at the bottom turn yellow first, this is the main factor of your gardenia yellow leaves, most plants are to consume the nutrients of the old leaves to resume growth after changing pots, so don't worry too much.

What should be paid attention to when raising gardenias.

1. When choosing potting soil, you can choose the soil prepared for rhododendrons and camellias, that is, acidic soil. Gardenias enter a short period of growth arrest after flowering, so they can be fertilized in spring and summer, and not again after autumn.

2. When watering and fertilizing, avoid watering the leaves, let alone let the flowers get wet. It is best to water and fertilize the surface of the soil. Water more often in spring and summer, and reduce the frequency of watering after the flowering period.

Watering must be done with room temperature water, preferably tap water that has been left on for a day.

It would be better if there was natural rain, and generally the tap water was alkaline, so it was necessary to apply acidic fertilizer to balance the needs.

3. If the light is indoor, the light is definitely not enough, and it is best to add artificial light. In winter, it is even more important to add light. For gardenias to bloom, in addition to sufficient light, high humidity is also required.

It is best to spray more around the air. Gardenias can be repotted every spring when they are young, and they should not be too diligent in changing pots after they are high songs. As long as the roots are not too urgent, there is no need to repot.

Friends who have raised gardenias know that gardenias are very easy to yellowing leaves, there are many reasons, a flower friend who has raised gardenias for 10 years, summarized some of the reasons why gardenia leaves are yellow, you can compare them according to your own situation, and then solve them in a targeted manner, you can do not ask for people, and you can also solve the problem of yellow leaves.

1. Overwatering.

The manifestations are: the yellowing of the leaves is from bottom to top, the old leaves are yellow first, the leaf veins are green, and then gradually the whole area is yellow.

Low temperature water yellow. Causes: Poor indoor ventilation. The potting soil is too sticky, too fine, permeable, and has poor air permeability, as well as good soil moisture retention and excessive watering. Watering the bubble pot too often. Sudden cooling of the soil when it is wet.

The potting soil is too sticky, resulting in a lot of water.

The new pot is too large, the new fill layer is too thick, and the root system of gardenia in the slow seedling stage cannot reach the edge of the pot. The branches and leaves at the bottom layer are too dense, which affects the ventilation of the soil surface. Sandwich soil, the outer layer of loess in the nutrient soil in the new pot, or the inner loess and the outer nutrient soil.

Extremely cold air-conditioned room in summer. Flower pots have poor air permeability and poor heat dissipation.

You can judge according to your own situation, it may be caused by one reason, or it may be caused by multiple reasons, and then you can determine how to solve it.

2. Excessive fertilization.

The performance is that the veins of the old leaves of gardenia are yellow, but the surrounding area is still green.

Cause: The concentration of fertilizer applied to gardenias is too large.

Solution: If you find this situation, you should change the water blister pot (many times) as soon as possible, or irrigate the roots, that is, use very fine water to water all the time, about half an hour, the purpose is to dilute the overly concentrated fertilizer in the soil.

3. Iron deficiency yellow.

The manifestations are: the new leaves of gardenia are yellow, specifically the veins are green, and the mesophyll is white-green.

Cause: Lack of iron.

Solution: Use alum fertilizer water (ferrous sulfate, dried manure, cake fertilizer and water, press 1:3:

The ratio of 5:100 is prepared, and the black-green liquid becomes after full fermentation) or ferrous sulfate and white vinegar spray leaves or direct watering, the effect of alum fertilizer water is obvious, and the roots are significantly improved after a few days.

4. The soil is alkaline.

Most flowers in the south prefer acidic soils, while the soil in the north is alkaline, which will cause the gardenias from the south to suffer from alkali damage and cause yellowing of leaves.

Solution: Replace the cultivation soil with peaty soil or sulfur powder. These southern flowers and trees should be watered with ferrous sulfate once a week; Keep the potting soil loose and drained smoothly; Or soak the grass in water, and after the grass rots, water the flowers with supernatant to reduce the occurrence of alkali damage.

5. Hard water in the north.

In addition, most of the water in the north is hard water (refers to water containing more soluble calcium and magnesium compounds), and the common use of hard water to water flowers will promote the increase of lime content in the soil and compaction, which is not conducive to the growth of the root system, and at the same time cause the leaves to gradually turn yellow and wither.

Solution: Vinegar water can be poured 1 time every 2 3 weeks, or it can be sprayed on the plants by adding 2 tablespoons of vinegar to 1 liter of water, which can prevent the leaves of gardenias in the south from yellowing and make them grow better.

Heavy water or lack of fertilizer may cause yellowing of leaves. If you water too much, it is easy to rot the roots, resulting in insufficient nutrients, and the leaves will turn yellow; In addition, too much fertilizer can damage gardenias, and excess iron can also cause yellow leaves.

It should be less water, and the dry and yellow leaves of gardenia should be a lack of water, and they are not watered often, because gardenias need water very much, and without water, the leaves will turn yellow.

This should be a lack of water or a lack of fertilizer. We need to hydrate it in time and fertilize it to replenish nutrients.

There are many reasons why gardenia leaves turn yellow:

1.Lack of light causes gardenia leaves to turn yellow, 2Overwatering causes gardenia leaves to turn yellow, 3Lack of fertilizer causes yellowing of gardenia leaves,4The potting soil is too alkaline, causing the leaves of gardenia to turn yellow.
