Grow jasmine like this in summer and buds will keep bursting out, blooming for more than half the year

What should you do if jasmine leaves turn yellow and fall off?

Jasmine leaves turning yellow generally has 3 causes:

1. Improper watering

When overwatered, the jasmine roots have poor air permeability, so the young leaves lose their luster and gradually turn yellow and wither, while the old leaves change little; when underwatered, water absorption is insufficient, and the old leaves gradually fall off from top to bottom.

Solution: The number of waterings depends on how dry or moist the potting soil is and the weather. Keep the potting soil moist but not soggy. After rain, pour off any standing water promptly to prevent root rot.

2. Improper fertilizing

When there is too much fertilizer, the jasmine's new leaves turn brown, and the old leaves gradually wither, yellow and fall off; when there is a lack of fertilizer, the leaves do not get enough nutrients and turn yellow.

Solution: When there is too much fertilizer, repot and change the soil promptly; when there is a lack of fertilizer, apply a top dressing promptly. Fertilize according to the principle of light fertilizer applied frequently.

3. Soil on the alkaline side

Jasmine likes a slightly acidic growing environment. If the potting soil of northern growers is on the alkaline side, it can also cause yellow leaves and leaf drop.

Solution: Adjust the soil's acidity and alkalinity. You can dilute vinegar with water 1000 times and pour it into the soil, or ferment fruit peels and cores in water to make fertilizer and then water the flowers with it.

What should you do if jasmine drops its flower buds?

Jasmine dropping flower buds and flower buds generally has 2 causes:

1. Adapting to a new environment

A newly bought jasmine needs to consume a lot of nutrients to adapt to the new environment, and at this time it can only sacrifice flower buds to save nutrients.

Solution: Pinch off all the flower buds, then prune some healthy branches and leaves, then place it in a cool, ventilated spot to recover for a week before returning to normal care.

2. Insufficient light

Jasmine likes light and needs plenty of sunlight during growth. Insufficient light will cause the branches and leaves to grow leggy, and it will either drop buds before blooming or bloom with few and small flowers.

Solution: First prune the leggy branches and leaves, then place the pot on a sunny south-facing balcony or windowsill for care, as long as it is not exposed to strong midday sun.

What should you do if jasmine roots rot?

1. Prune the rotten roots

After discovering root rot, take the jasmine out of the pot, gently shake off the soil, rinse it clean with water, and then cut off the rotten roots.

2. Sterilize and disinfect

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

3. Repot and transplant

Put a layer of crushed stone or coal cinder at the bottom of the prepared flower pot, then fill it with soil and transplant. The soil can be made by mixing loose leaf mold and sandy soil.

How should jasmine be grown in summer?

Watering

When the temperature is high, jasmine evaporates water quickly. Water it once each morning and evening to keep the potting soil moist but not waterlogged. If the air is dry, also spray water frequently.

Light

If you want jasmine to bloom a lot, you must ensure sufficient light. As long as it is not exposed to strong midday sun, the more light it gets at other times, the better it blooms.

Fertilizing

Summer is the peak blooming period for jasmine. To ensure blooming, apply a top dressing of decomposed cake fertilizer water or compound fertilizer once every week. Only with sufficient fertilizer and water can it bloom abundantly and with large flowers. Note that you must not fertilize when the potting soil is dry.

Pruning

Jasmine grows fast in summer, so prune overly dense tangled branches promptly. When pruning, keep 10~15cm at the base to encourage new branches to sprout. After the flowers fade, prune the flowering branches promptly to reduce nutrient consumption and ensure the next bloom.

Pest and disease control

1. Red spider mite

In summer, if ventilation is poor, jasmine is most prone to red spider mites. Red spider mites harm the tender leaves at the top, causing yellow patches on the leaves, and in severe cases the leaves wither, yellow and fall off.

Solution: When infection is found, first cut off the diseased leaves, clear away dead branches and fallen leaves, then spray. When spraying, pay attention to 2 points:

1. Red spider mites have strong reproductive ability and easily develop resistance, so you must rotate the pesticides used. Options include 25% azocyclotin wettable powder 1000~2000 times solution, 20% dicofol 1000~1500 times solution, 5% flufenoxuron emulsifiable concentrate 500~1000 times solution, etc.

2. To wipe out red spider mites, it is best not to use dichlorvos and dimethoate. These two pesticides have too strong an odor that will not dissipate for many days, are bad for human health, and are not specific remedies either.

2. Anthracnose

Anthracnose generally occurs on the leaves, starting as small yellow-green spots that gradually expand into gray-white or gray-brown round spots.

Solution:

When infection is found, first remove the diseased leaves, then spray a little 70% carbendazim 600~800 times solution, once every 7~10 days, for 3 times in succession.

If the diseased spots are relatively severe, spray 50% thiophanate-methyl, 75% chlorothalonil wettable powder 800~1000 times solution, or 50% carbendazim 1000 times solution.

3. Southern blight

Southern blight is the most serious disease of jasmine. It mainly occurs at the stem base near the ground, producing white mycelium on the surface, with the bottom gradually rotting, and in severe cases the whole plant will wither and die.

Solution:

In the early stage of the disease, spray a little 50% amobam 1000 times solution around the diseased area and the soil, once every 7~10 days, to inhibit the spread of the disease.

When the disease is severe, you must pull it out by the roots, remove the diseased plants, destroy them in a concentrated way, and use 86.2% copper master 800~1200 times, 50% amobam 500 times solution, or apply lime powder to drench the soil for disinfection.
