What to do with the yellowing of two-color jasmine leaves? the solution of two-color jasmine not blooming

Two-color jasmine is a more valuable variety, very interesting, its English name means "yesterday, today, tomorrow", which also vividly describes the change of its design and color. Two-color jasmine blossoms from yesterday's dark blue to today's purple and then to tomorrow's white, which makes many flower friends unconsciously fall in love with it. But it's a bad problem if the leaves turn yellow during the discoloration process.

What if the leaves of two-color jasmine turn yellow?

1. Improper watering. The yellow leaves caused by long-term watering showed that the young leaves had no luster, the old leaves had no obvious change, the roots were small yellow-green, and the new shoots shrunk not long.

Measures: should be controlled watering, heavy can take off the basin, put in the shade to dry the soil and then re-basin.

2. Improper fertilization. Due to excessive fertilization or excessive concentration, the new leaf tip appears dry brown, the old leaf tip dry scorch withered yellow shedding, although the general leaf surface is thick and shiny, but mostly uneven.

Measures: stop fertilizing or washing fertilizer with clean water. Potted flowers only water for a long time, or do not change pots for many years, the roots must form a ball, the plant can not get fertilizer points, so that leaves yellow, in addition to timely change pots, usually should be thin fertilizer diligently. 3. Improper illumination. Pot two-color jasmine lack of light for a long time, the chlorophyll in the leaves decreased, so that the green leaves gradually disappeared, showing albinism.

Measures: move the plant to a sunny place to make the leaves turn green slowly.

4. The soil is alkaline. Bicolor jasmine is a kind of flower that likes acid soil. If the pot soil or water quality is too alkaline, it often causes the leaves to change from green to yellow, or even fall off.

Measures: in addition to using acid nutritious soil to carry culture, you can use alum fertilizer water or 0.2% Mel 0.5% ferrous sulfate solution spray, which can make the leaves change from yellow to green.

5. The temperature is uncomfortable. Two-color jasmine is not resistant to high temperature, high humidity, yellowing caused by hot summer, bad storm and improper shade avoidance.

Measures: pay attention to ventilation and cooling, and the basin soil should not be overheated. In addition, in the cold winter, such as low indoor temperature, the leaves of bicolor jasmine will turn yellow and fall off. In addition, it can also cause yellow leaves to fall off when harmed by diseases and insect pests. It is normal if a few leaves turn yellow and fall off in the lower part of the plant.

The solution of non-flowering of two-color jasmine

1. Pruning in time

When bicolor jasmine grows to a certain height, cut off the leaves and buds at the top in time, do not be distressed, this can promote multiple lateral branches. If there are too many branches, there is no need to worry. The flower buds of one or two branches are not growing well.

2. Fertilization before flowering

Fertilization began one month before flowering, focusing on topdressing phosphorus and potassium fertilizer, reducing nitrogen fertilizer, ensuring adequate nutrient supply of flower buds, enhancing the resistance of plants, and blooming more naturally.

3. Plenty of sunshine

If there is not enough fertilizer, the sun will gather together. Sufficient sunlight exposure, the plant can accumulate sufficient nutrients, timely insufficient fertilization, but also can support for a period of time. Bask in the sun, but don't expose yourself to the sun.

The reason why two-color jasmine does not bloom

1. Improper fertilization

Some flower friends' two-color jasmine only grows leaves but does not blossom, mainly because of improper fertilizer and too much nitrogen fertilizer, resulting in exuberant growth of branches and leaves, lack of phosphorus and potassium fertilizer, and flower buds can not differentiate. The growth of leaves consumes most of the nutrients, and it is difficult to differentiate flower buds.

2. Improper watering

The two-color jasmine grows vigorously, the water is replenished in time, and everything seems to be normal, but it is this normal watering method that causes the two-color jasmine not to bloom. There is no problem with watering at ordinary times, but the branches and leaves grow luxuriantly, but there are no flowers. This is because the leaves grow only because of sufficient water, and it is inevitable to affect flowering.

3. Pruning

Bicolor jasmine is a woody plant that is resistant to pruning. In the time of flower bud differentiation, if the flower bud is not pruned in time, the flower bud will grow poorly, which will fall ahead of time and affect flowering.

How to raise two-color jasmine

1. Soil requirements

Two-color jasmine is generally cultivated in East China and North China, which is suitable for slightly acidic soil with good drainage and air permeability.

2. Temperature

The suitable temperature for the growth of bicolor jasmine is 20-30 ℃. At this temperature, the branches and leaves are luxuriant and the growth is vigorous. When the temperature drops to 12 ℃, it warms up and enters the dormant period, which is not cold-resistant. Pay attention to timely indoor maintenance in winter to avoid frostbite.

3. Lighting

Two-color jasmine likes sunny, moist environment, avoid scorching sun exposure, summer needs appropriate shade. Too much sun exposure, flowers and leaves are easy to curl. The light time should not be less than 4 hours a day, which can ensure blooming and luxuriant.

4. Watering

Two-color jasmine likes to be moist and afraid of waterlogging, and watering should adhere to the principle of seeing dry and wet. Summer watering should be paid attention to, not only to meet the needs of plant growth, but also to keep the air moist, spraying water to the leaves 2-3 times a day. Keep the basin soil dry in winter to prevent frostbite.

5. Fertilization

It is necessary to irrigate alum fertilizer and water in time during the growing period, which can not only prevent soil Alkalization and leaf yellowing, but also increase soil fertility and promote plant growth. After the flowers withered, a thin cake fertilizer was applied, and 10 days later, a liquid fertilizer based on phosphorus and potassium fertilizer was applied, and combined with watering, potassium dihydrogen phosphate solution was sprayed to the leaves to promote flower bud differentiation.

The reason why the leaves of two-color jasmine turn yellow and do not blossom has a lot to do with the daily maintenance of flower friends. Its flowers are beautiful, but they can't stand trouble, so we should pay more attention to it when planting bicolor jasmine.
