If you grow jasmine like this in summer, the flower buds will pop non-stop and will bloom for half a year!

What should I do if the leaves of jasmine turn yellow and fall off?

There are generally three reasons why jasmine leaves turn yellow:

1. Improper watering

When watering too much, the jasmine root will have poor air permeability, and the young leaves will become dull, gradually turn yellow and wither, while the old leaves will not change much; when watering too little, the water is not absorbed enough and the old leaves will gradually fall off from top to bottom.

Solution: The frequency of watering should be determined according to the dryness of the potting soil and the weather. Make sure the potting soil is moist but not wet. Pour out the accumulated water in time after rain to prevent root rot.

2. Improper fertilization

When jasmine is overfed, the new leaves turn brown and the old leaves gradually turn yellow and fall off; when there is a lack of fertilizer, the leaves do not get enough nutrition and turn yellow.

Solution: Change the pot and soil in time when the plant is full of fertilizer, and apply top dressing in time when there is a lack of fertilizer. Fertilization should be done according to the principle of applying small amounts of fertilizer frequently.

3. Soil is alkaline

Jasmine prefers an acidic growing environment. If the potting soil of northern flower lovers is alkaline, it will also cause yellowing leaves and falling leaves.

Solution: Adjust the acidity and alkalinity of the soil. You can dilute vinegar 1000 times with water and use it to irrigate the soil. You can also dilute fruit peels and cores with water to make fertilizer and then use it to water the flowers.

What should I do if jasmine buds fall off?

There are generally two reasons why jasmine flowers drop their buds and flower buds:

1. Adapt to the new environment

Newly bought jasmine flowers need to consume a lot of nutrients to adapt to the new environment. At this time, you can only sacrifice the flower buds to save nutrients.

Solution: pinch off all the flower buds, trim some strong branches and leaves, then place them in a cool and ventilated place for a week before carrying out normal maintenance.

2. Insufficient light

Jasmine likes light and needs sufficient light during its growth process. Insufficient light will cause the branches and leaves to grow too long, and the buds will either fall off before blooming, or the flowers will be few and small.

Solution: First trim the overgrown branches and leaves, then place the flower pot on a south balcony or windowsill where there is sufficient light for maintenance, as long as it is not exposed to strong sunlight.

What should I do if the jasmine roots rot?

1. Prune rotten roots

When you find rotten roots, take the jasmine out of the pot, gently shake off the soil, rinse it with clean water, and then cut off the rotten roots.

2. Sterilization

Place the trimmed roots in potassium permanganate or carbendazim solution, soak for 2 to 3 hours, and then place in a ventilated and cool place to dry.

3. Repotting and transplanting

Place a layer of gravel and coal slag at the bottom of the prepared flower pot, then fill it with soil and transplant it. The soil can be prepared by mixing loose leaf mold and silt.

How to grow jasmine in summer?

Watering

When the temperature is high, the moisture of jasmine evaporates quickly. Water it once in the morning and evening every day to keep the soil moist but not waterlogged. If the air is dry, spray water frequently.

illumination

If you want jasmine to bloom more, you must ensure that it has sufficient light. As long as it is not exposed to strong sunlight at noon, the more light it gets at other times, the better the flowering.

Fertilization

Summer is the peak flowering period of jasmine. To ensure flowering, apply decomposed cake fertilizer or compound fertilizer once every week. Only with sufficient fertilizer and water can the flowers bloom more and larger. Note that fertilizer should not be applied unless the soil in the pot is dry.

prune

Jasmine grows fast in the summer, so it is necessary to prune the dense branches in time, and keep the bottom 10 to 15 cm when pruning to promote the sprouting of new branches. After the flowers fade, cut off the branches in time to reduce nutrient consumption and ensure the next flowering.

Pest control

1. Red spider

If ventilation is poor in summer, jasmine is most likely to be infested with red spider mites, which will harm the tender leaves at the top, causing yellow spots to appear on the leaves, and in severe cases the leaves will turn yellow and fall off.

Solution: When infection is discovered, first cut off the diseased leaves, remove the dead branches and leaves, and then spray the pesticide. Pay attention to two points when spraying:

1. Red spider mites have strong reproductive capacity and are prone to develop drug resistance, so it is necessary to rotate the drugs. The optional drugs include 1000~2000 times diluted 25% triazotin wettable powder, 1000~1500 times diluted 20% dicofol, 500~1000 times diluted 5% carbendazim emulsifiable concentrate, etc.

2. To eliminate red spider mites, it is best not to use DDT and Dimethoate. The odor of these two pesticides is too strong and will not dissipate for many days. They are not good for the human body and are not specific medicines.

2. Anthrax

Anthracnose usually occurs on leaves, starting as small yellow-green spots that gradually expand into grayish white or grayish brown circular spots.

Solution:

When infection is discovered, first remove the diseased leaves, then spray some 70% Leke 600~800 times diluted, once every 7~10 days, and do it for 3 consecutive times.

If the lesions are severe, spray 50% thiophanate-methyl, 800-1000 times diluted 75% thiophanate-methyl wettable powder or 1000 times diluted 50% carbendazim.

3. Sclerotinia rot

White rot is the most serious disease of jasmine, which mainly occurs at the base of the stem close to the ground. White mycelium is produced on the surface and the bottom gradually rots. In severe cases, the whole plant will die.

Solution:

In the early stage of the disease, you can spray 1000 times diluted 50% mancozeb around the diseased area and soil once every 7 to 10 days to inhibit the spread of the disease.

When the disease is serious, the plants must be pulled out by the roots, the diseased plants must be removed and destroyed in a centralized manner, and the soil must be disinfected with 800-1200 times of 86.2% Copper Master, 500 times of 50% Mancozeb or lime powder.
