What to do when jasmine's tender leaves turn yellow? Care for jasmine like this in summer

What should you do when jasmine leaves turn yellow and drop off?

There are generally 3 causes of yellowing jasmine leaves:

1. Improper watering

When watered too much, the jasmine roots do not get enough air, and the tender leaves lose their luster and gradually turn yellow and wither, while the older leaves change little; when watered too little, the plant does not absorb enough water, and the older leaves gradually drop from top to bottom.

Solution: The number of waterings should be determined by how dry or moist the potting soil is and by the weather, keeping the soil moist but not wet. After rain, pour off any standing water promptly to prevent root rot.

2. Improper fertilizing

When too much fertilizer is applied, the jasmine's new leaves turn brown, and the older leaves gradually wither, yellow and drop off; when fertilizer is lacking, the leaves do not get enough nutrients and turn yellow.

Solution: When too much fertilizer has been applied, repot with fresh soil promptly; when fertilizer is lacking, topdress promptly. Fertilize according to the principle of light, frequent applications.

3. Alkaline soil

Jasmine likes a somewhat acidic growing environment. If the potting soil of gardeners in the north is alkaline, it can also cause yellowing and falling leaves.

Solution: Adjust the soil's acidity and alkalinity. You can dilute table vinegar with water at 1:1000 and pour it into the soil, or compost fruit peels and cores with water and use the liquid to water the plant.

What should you do when jasmine drops its flower buds?

There are generally 2 causes of jasmine dropping its flower buds and buds:

1. Adjusting to a new environment

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

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

2. Insufficient light

Jasmine loves light and needs plenty of it during growth. Insufficient light will cause the branches and leaves to grow leggy, and the plant will either drop its buds before blooming or bloom sparsely and small.

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

What should you do when jasmine has root rot?

1. Prune the rotted roots

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

2. Sterilize and disinfect

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

3. Repot and transplant

Put a layer of crushed stone or coal cinders at the bottom of the prepared pot, then fill with soil and transplant. A loose mix of leaf mold soil and sandy soil can be used.

How do you care for jasmine in summer?

Watering

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

Light

For jasmine to bloom abundantly, you must ensure sufficient light. As long as it is not exposed to harsh midday sun, the more light it gets at other times, the better it blooms.

Fertilizing

Summer is jasmine's peak blooming season. To ensure blooming, topdress once every week with decomposed cake fertilizer water or a compound fertilizer. Only with ample fertilizer and water will it bloom abundantly and large. 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 shoots 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 mites

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

Solution: When an infestation 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 capacity and easily develop resistance, so you must rotate the pesticides used. Options include 25% azocyclotin wettable powder at 1000~2000 times dilution, 20% dicofol at 1000~1500 times dilution, 5% flufenoxuron emulsifiable concentrate at 500~1000 times dilution, etc.

2. To kill red spider mites, it is best not to use dichlorvos and dimethoate. These two pesticides have a very strong odor that does not dissipate for many days, are bad for human health, and are not specific remedies.

2. Anthracnose

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

Solution:

When an infestation is found, first remove the diseased leaves, then spray a little 70% thiophanate-methyl at 600~800 times dilution, once every 7~10 days, for 3 treatments in a row.

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

3. Southern blight

Southern blight is the most serious disease of jasmine. It mainly occurs at the stem base near the ground, where white mycelium appears on the surface, the base gradually rots, and in severe cases the whole plant withers and dies.

Solution:

In the early stage of the disease, spray a little 50% amobam at 1000 times dilution on the disease and around the soil, once every 7~10 days, to suppress the spread of the disease.

When the disease is severe, you must pull the plant out by the roots, remove the diseased plants, destroy them centrally, and disinfect the soil by drenching with 86.2% copper hydroxide at 800~1200 times dilution, 50% amobam at 500 times dilution, or by applying lime powder.
