The leaves begin to turn yellow and fall off may be caused by too much watering, and if the gardenia is watered too much, it will rot its roots. At this point, its leaves will wrinkle, yellow, or even fall off. If it is in its flowering stage, its flowers may also wither early.
After discovering that there is too much watering, gently pick the bark of the trunk, if it is bright green, it may be saved. First, watering should be stopped immediately, and the soil should be loosened to speed up the evaporation of water; Second, it can be taken out of the culture soil in time, and if it is serious, it is necessary to remove the wet mud of the root system, trim off the rotten roots, clean the flower roots with carbendazim or chlorothalonil, and cut off most of the branches and dry them in the shade for two or three days, and then replant them in the new soil and maintain them slowly. If it is not a lot of water, it may be a lack of phosphorus and potassium fertilizer, you can go to the market to buy it and water it with good water in proportion.
Gardenias are suitable for growing in acidic soils. Likes moisture and is afraid of dryness. Potted plants that are not watered for a few days will die of drought.
Fertilizer-loving, can often apply water containing ferrous sulfate, alum fertilizer water or corrosive fertilizer. Resistant to high temperatures, it can grow even at 40 degrees Celsius. It is resistant to severe cold, and will not freeze to death even if it is about 10.
Gardenias love sunlight, but should not receive strong direct sunlight. When planting, there should be a shady environment, shading can make the leaf color tender green and shiny, otherwise it is easy to burn the leaves and cause leaf yellow, leaf scorch. Gardenias like moisture and fertilizer, and potted plants in summer should pay special attention to watering in the morning and evening, so that the potting soil often insists on being moist.
During the hot summer season, spray the foliage with clean water every morning and evening, and sprinkle water on the nearby ground to increase the humidity of the air. When there is a lot of rain, you should pay attention to drainage, otherwise it will make the roots rot and the leaves yellow. In the spring, you can cut off overly long branches, weak branches, and other branches that affect the shape of the plant.
Gardenia flowers at the top, and top topping can be appropriately carried out during the growing season to promote the growth of flower branches and increase the number of flowers.

If your gardenia leaves are starting to turn yellow and fall off, it's most likely due to overwatering. Overwatering can lead to hypoxia and root rot in the roots, which can affect the nutrient absorption and metabolism of plants.
Here are some things you can do to try to alleviate the problem of overwatering your gardenias:
1.Stop watering: First, you need to stop watering immediately and let the soil dry out somewhat. This prevents the roots from rotting further and aids in plant recovery.
2.Loosening the soil: After the soil has dried, you can loosen the soil to help with air circulation, which helps the roots get enough oxygen.
3.Moderate light: Gardenias need plenty of sunlight, but avoid sun exposure. Giving gardenias the right amount of light can help the leaves recover.
4.Fertilization: During the gardenia recovery period, some moderate amount of fertilizer can be applied to help the plant recover health. But pay attention to the fertilizer concentration and frequency so as not to stress the plant again.
If your gardenia condition is severe, you may want to consider replanting your gardenias. When replanting, you need to choose the soil and environment that is suitable for your gardenias, and pay attention to proper watering to avoid problems again.

The first is to get a barefoot ventilated place. Second, it is necessary to immediately loosen the soil and disperse the water. Third, spray foliar fertilizer. Water when the soil is dryThe ternary compound fertilizer is used once to keep the seedlings slow.

Add a little rotting fertilizer with plant ash and you're good to go. ** Seven Channel Agricultural Vast World has let go, like this situation of the plant.

Gardenia if overwatered (daily watering is equal to long-term rain and heavy waterlogging rotten roots), drought (potting soil has dried up and not watered in time), culture soil compaction (root system is not breathable), barren (lack of fertilizer), application of thick fertilizer (burning roots), lack of sunlight will cause yellow leaves and leaf loss.
Gardenia leaves are yellow, where overwatering (waterlogging), lack of fertilizer, lack of iron, lack of sunlight, pests and diseases (insect traces and lesions can be seen, very rare), these five conditions will produce leaf yellow, but the state of yellow is different:
The young leaves are dark yellow and dull, the old leaves have no obvious changes, the branches are small yellow-green, and the new shoots are shrunk and not long, indicating excessive watering. Depot the flowers, put them in a ventilated and cool shade, and dry the soil ball before putting them back into the pot. The yellow of drought and water deficiency is not the same as the yellow of water more, the yellow of water shortage is the withering and dry leaf tips or edges, and the old leaves are withered and yellow from the bottom to the top, but the growth of new leaves is relatively normal.
Pay attention to watering when watering enough, water thoroughly. Seared yellow.
Strong sunlight directly onto some shade-loving flowers (such as spider plants, hostas, etc.) is easy to cause the leaf tips and leaf margins of flowers to wither, and the sunny part of the leaves to appear yellow spots. Move to the pubic area. Lack of light yellow.
If the leaves are shaded for a long time, the leaves will not get enough sunlight to form chlorophyll, and the whole leaves will turn yellow and then fall off, and this disease can be avoided by supplementing light. The yellowing of flowers caused by excessive fertilization or excessive concentration is manifested in dry brown at the top of the new leaves, and the general leaf surface is thick and dull, and the concave and convex are not stretched, and the old leaves are scorched and peeled off. Fertilization should be stopped immediately, and part of the fertilizer should be washed with plenty of washing in severe cases.
Lack of fertilizer yellow is manifested in the color of young leaves becoming lighter, yellow or light green, while old leaves are more normal or gradually turning from green to yellow. Check the potting soil, if there is a dry knot, the soil should be changed, and the thin fertilizer should be applied frequently and some alum water should be poured in a timely manner.

The main reason for this blackening and dryness is the root system, which is what we call rotten roots. Why is it said that the black leaves of gardenias are rotten roots? In fact, if most plants have black leaves and rotten leaves, it is a problem with the root system, if the potting soil is compacted, you can't water it thoroughly, its root system will have dry roots, which will cause its leaves to appear yellow.
The method of treatment is to mop the soil and change the pot, check the root system, prune the root system, soak the root system in the aqueous solution of carbendazim to prevent the recurrence of rotten roots, you can add some rooting solution when soaking, and then go to him for new soil cultivation, the new soil must do a good job of sterilization. After cultivating it in this way, put it in a well-ventilated place, you can see a little scattered light, don't over-water the potting soil, dry down two or three centimeters and then water it, the soil must be better permeable, so that the gardenia we raise will recover quickly.

Gardenias are often susceptible to yellowing of leaves, which is caused by a variety of reasons, so different measures must be taken to prevent and control them. Yellowing caused by lack of fertilizer: This yellowing disease starts from the old leaves in the lower part of the plant and gradually spreads to the new leaves.
Nitrogen deficiency: simple leaf yellow, new leaves small and brittle. Potassium deficiency:
The old leaves turn green to brown. Phosphorus deficiency: The old leaves are purplish-red or dark red.
In all cases, you can be forced to apply rotten human feces or cake fertilizer. Yellowing caused by iron deficiency: This yellowing disease, manifested on new leaves, is pale yellow or white at the beginning, the leaf veins are still green, and in severe cases, the leaf veins are also yellow or white, and eventually the leaves will dry up and die.
In this case, the aqueous solution of ferrous sulfate that can be sprayed can be prevented. Yellowing caused by magnesium deficiency: This yellowing disease begins to develop from old leaves to new leaves, and the leaf veins are still green, and the leaves fall off and die in severe cases.
In this case, boron and magnesium fertilizer can be sprayed to prevent and control. Excessive watering, freezing, etc., can also cause yellow leaves, so special attention should be paid during the maintenance process. Gardenia is prone to scale insect damage and is accompanied by soot disease when the indoor ventilation is poor and the temperature and humidity are too high in winter.
For scale insects, bamboo skewers can be used to scrape off, and No. 20 petroleum emulsion can also be sprayed with 200 times water. For soot disease, it can be scrubbed with water, or sprayed with carbendazim 1000 times for prevention and control.

<> the leaves of gardenias in winter are yellow and dry and the leaves are withered, you can use scissors to cut off the leaves of the plants that are yellow, and then apply disinfectant to the wounds of the gardenia to prevent the wound from being infected with bacteria, and finally apply diluted nitrogen fertilizer to the plants to supplement nutrients for the gardenia and promote the growth of new leaves.
1. Prune.
In winter, the leaves of gardenia are yellow and withered, it is best to use sharp scissors to cut off the dry and yellow leaves of the plant to reduce the consumption of nutrients by gardenias, and then apply disinfectant to the wound of the plant to avoid the wound being infected with bacteria.
2. Provide nutrients.
After the gardenia is pruned, you can apply some nitrogen fertilizer to the plant to supplement the nutrients for the gardenia, so as to promote the rapid recovery of the plant.
3. Provide moisture.
When cultivating gardenias in winter, it is best to water the plants every 1-3 weeks, and the amount of watering needs to be controlled, so that the soil can produce waterlogging, otherwise it will affect the health of gardenias.
4. Precautions.
When cultivating gardenias, you can loosen the soil for the plant every other time to prevent the root system of the plant from being black and rotten due to the impermeable soil, if the root system of the plant is black and rotten, it needs to be cut off in time with scissors, so as not to affect the health of the gardenia.
