Gardenia trees planted in pots, what to do if the yellow leaves fall off

During the growth of gardenias, the leaves often turn yellow, and the reason is mostly caused by poor cultivation management. Too much water, too little sunlight, too much or too little fertilizer will cause yellowing of leaves, but the yellowing situation is different, and the causes should be carefully observed and analyzed, and corrected.

1. Water yellow. 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.

2. Dry yellow. The yellow of lack of water is different from the yellow of water, the yellow of lack of water 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.

3. Burnt yellow. Strong sunlight directly shines on some shade-loving flowers, which 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.

4. 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.

5. Fat yellow. 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 yellow. Fertilization should be stopped immediately, and part of the fertilizer should be washed with plenty of washing in severe cases.

6. Lack of fat yellow. It 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.

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 leaves need to be pruned off, the soil is regulated, the light is increased, the water is replenished, and the rotten roots are pruned.

1. Prune off the yellow leaves.

The leaves of gardenias appear yellow, dry or lose leaves, and the yellow leaves and dead leaves need to be pruned off to avoid nutrient consumption.

2. Regulate the soil.

Gardenia leaves yellowing and withering leaves, may be caused by soil acidity and alkalinization, plants like acidic soil, soil alkalinization will lead to poor growth, this time to watering gardenia peel water or vinegar, so that Wang You can adjust the pH of the soil, so that the soil is acidified.

3. Increase the light of the mausoleum bureau.

Insufficient light can also cause gardenia leaves to turn yellow and dry up, because gardenia is a light-loving plant, which is very suitable for growing in a well-lit environment, and plants without sufficient light will grow poorly. Gardenias can be grown outdoors or on a balcony in a sunny environment.

4. Replenish water.

Gardenia leaves yellow falling, may also be caused by too little watering, to timely add sufficient water for gardenias, to maintain the moisture of the soil, in the watering process, to water in the soil, until the bottom of the pot water flowed out.

5. Prune rotten roots.

When the gardenia is growing, if the roots rot will also cause the leaves to turn yellow and fall, at this time the gardenia plant should be dug up, pruned off the rotten roots, and then soaked in carbendazim solution, and replanted after the wound has healed.

Yellow gardenia leaves may fall due to the following reasons:1Improper maintenance:

Gardenia needs plenty of sunlight and suitable temperature and humidity, and if it is not properly maintained, such as overwatering or lack of water, excessive fertilization or lack of fertilizer, etc., it will cause the gardenia to lose its leaves. 2.Pests and diseases:

Gardenia is susceptible to pests such as aphids, whiteflies, and spider mites, and is also susceptible to infection with germs, such as mold, bacteria, etc., causing gardenia to lose its leaves. 3.Growth Cycle:

It is normal for gardenia to have a certain defoliation period in the growth cycle. In view of the above reasons, the following measures can be taken:1

Maintenance attention: maintain appropriate temperature, humidity and light, avoid overwatering or lack of water, excessive fertilization or lack of fertilizer, etc. 2.

Pest control: Regularly inspect the leaves and branches of gardenia, and take timely measures to prevent and control pests and fungi. 3.

Wait for the defoliation period to end: If the gardenia is in the normal defoliation period, you can wait for the defoliation period to end for proper pruning and maintenance. In conclusion, the loss of leaves from gardenia can be caused by a variety of reasons, and corresponding measures need to be taken to deal with it according to the specific situation.

Yellow gardenia leaves are lost, and it is advisable to place them in a well-ventilated, bright place or under scattered light, not too shade and poor ventilation. The air humidity requirement is above 75%, and when it is lower than 50%, it will yellow leaves and produce leaf diseases. Watering to see dry and wet, the pot soil is dry to be ready to dismantle the watering, that is to say, the surface of the pot soil is slightly dry when the watering, it is best not to have a regular interval, because watering is affected by the cloudy, air humidity, temperature and other factors, note that if the pot soil has large or more skin cracks, it is necessary to water frequently or change the soil seriously with a large amount of cleaning and flushing part of the fertilizer.

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 phenomenon, the soil should be replaced, usually thin fertilizer is applied diligently and some imitation jujube alum water is poured in a timely manner.

Gardenia is an acid-loving plant, in addition to watering, fertilizer and other factors will cause gardenia yellow leaves, there is also a yellow leaf reason: iron deficiency yellow leaves, in daily watering can add ferrous sulfate with water to water gardenias, can effectively avoid iron deficiency yellow leaves.

Gardenia yellow leaves fall off, the reason is basically here.

There are several cases of yellow leaves, one is newly transplanted. It was originally planted in the field, but it was dug out of the field before it was sold. In this way, the seedlings have a process of adaptation, and the leaves will yellow and fall. But it is often the end of the sail that lifts the blades yellow and falls.

The second is that the potting soil is too dry. Gardenias are moist, warm, and semi-shaded plants that cannot be exposed to the sun. It is best to put it in semi-shade, or in the shade of a large tree. The potting soil should be kept moist but avoid stagnant water.

3.There is a lack of iron in the potting soil. It will gradually turn all the leaves pale green until they turn yellow. It is necessary to water alum fertilizer or sulfuric acid with a concentration of one thousandth of the ferrous liquid in time.

4.The yellowing of the top is basically because the potting soil is too wet. or root injury.

Except for the third point, other leaf yellows cannot be reversed. It can only be made to fall.
