<p>Yesterday-today-tomorrow is a rather precious variety and very interesting; its English name means “yesterday, today, tomorrow,” which vividly describes the changes in its flower color. The flowers of yesterday-today-tomorrow change from yesterday's deep blue to today's purple and then to tomorrow's white, which has made many flower lovers fall in love with it without realizing it. However, if the leaves turn yellow during the color-changing process, that is a very bad problem.</p><p></p><p><strong>What to do if yesterday-today-tomorrow leaves turn yellow</strong></p><p>1. Improper watering. Yellow leaves caused by long-term watering are shown as young leaves turning yellow with no gloss, while old leaves show no obvious change, the roots are small and yellow-green, and new shoots shrink and do not grow.</p><p>Measures: Watering should be restrained; in severe cases, the plant can be removed from the pot, placed in a shady place to dry the soil, and then repotted.</p><p>2.

Bicolor jasmine (Bouvardia ternifolia / "Yesterday, Today and Tomorrow") is a rather rare and valuable variety, and a very interesting one. Its English name means "yesterday, today, tomorrow," which vividly describes the way its flower color changes. The flowers of bicolor jasmine open from yesterday's deep blue to today's purple and then to tomorrow's white, which has made many flower lovers fall in love with it without realizing it. However, if the leaves turn yellow during this color-changing process, that is a very troublesome problem.
What to do when bicolor jasmine leaves turn yellow
1. Improper watering. Leaf yellowing caused by long-term watering shows up as young leaves turning dull yellow without luster, while old leaves show no obvious change, the roots are thin and yellow-green, and new shoots shrivel and stop growing.
Measure: Watering should be restrained; in severe cases, the plant can be taken out of the pot, placed in a shady spot to let the soil dry, and then repotted.
2. Improper fertilizing. Because of too much fertilizer or too high a concentration, the tips of new leaves develop dry brown patches, and the tips of old leaves become scorched, withered, yellow and fall off. Generally, although the leaf surface is thick and glossy, it is mostly uneven.
Measure: Stop applying fertilizer or flush out the fertilizer salts with clean water. If a potted flower is given only water and no fertilizer for a long time, or is not repotted for many years, the roots become a tangled mass, the plant cannot get nutrients, and the leaves turn yellow. Besides repotting in time, usually apply light fertilizer frequently. 3. Improper lighting. Potted bicolor jasmine kept in insufficient light for a long time has less chlorophyll in its leaves, so the green color gradually fades and the plant shows signs of chlorosis.
Measure: Move the plant to a place with plenty of sunlight so the leaves slowly turn green again.
4. Alkaline soil. Bicolor jasmine is a flower that prefers acidic soil. If the potting soil or water is on the alkaline side, the leaves often turn from green to yellow and may even drop off.
Measure: Besides using acidic nutrient soil for cultivation, you can spray with alum fertilizer water or a 0.2%-0.5% ferrous sulfate solution, which can turn the leaves from yellow back to green.
5. Unsuitable temperature. Bicolor jasmine does not tolerate high temperatures or high humidity; yellowing is caused by hot summers, poor ventilation, and improper shading.
Measure: Pay attention to ventilation and cooling, and the potting soil must not be too warm. In addition, in the cold winter, if the indoor temperature is low, the leaves of bicolor jasmine will also turn yellow and drop. Moreover, damage from pests and diseases can also cause yellow leaves to drop. If only a few leaves at the lower part of the plant turn yellow and drop, that is normal.
Solutions for bicolor jasmine not blooming
1. Prune in time
When bicolor jasmine grows to a certain height, promptly cut off the leaves and flower buds at the top. Do not be reluctant to do it, because this can promote more side branches. Once there are more branches, there is no need to worry that the flower buds on one or two branch tips will grow poorly.
2. Fertilize before blooming
Start fertilizing one month before blooming, focusing on phosphorus and potassium fertilizer, reducing nitrogen fertilizer, ensuring an adequate nutrient supply for the flower buds, and strengthening the plant's resistance, so it will naturally bloom abundantly.
3. Plenty of sunlight
If fertilizing is not enough, let sunlight make up for it. With sufficient sunlight, the plant can accumulate adequate nutrients, and even if fertilizing is insufficient, it can hold out for a while. Give it more sun, but do not expose it to scorching sun.
Reasons bicolor jasmine does not bloom
1. Improper fertilizing
Some flower lovers' bicolor jasmine only grows leaves and does not bloom. The main reason is choosing the wrong fertilizer: too much nitrogen fertilizer causes vigorous growth of branches and leaves, while the lack of phosphorus and potassium fertilizer means flower buds cannot differentiate. The growth of the leaves consumes most of the nutrients, making flower bud differentiation more difficult.
2. Improper watering
Bicolor jasmine grows vigorously, and if water is replenished in time, everything seems normal, but it is exactly this normal watering method that prevents bicolor jasmine from blooming. Usually, ample watering is not a problem, but the branches and leaves grow very luxuriantly while not a single flower appears. This is because the leaves have grown leggy due to sufficient water, and this inevitably affects blooming.
3. Pruning
Bicolor jasmine is a woody plant and tolerates pruning. During flower bud differentiation, if it is not pruned in time, the flower buds grow poorly and will drop early, affecting blooming.
How to grow bicolor jasmine
1. Soil requirements
Bicolor jasmine is generally cultivated in East China and North China, and it is suitable for slightly acidic soil with good drainage and aeration.
2. Temperature
The suitable temperature for bicolor jasmine growth is 20-30°C. At this temperature, the branches and leaves are lush and growth is vigorous. When the temperature drops to 12°C, it becomes dormant, and it is not cold-tolerant. In winter, move it indoors in time to avoid frost damage.
3. Light
Bicolor jasmine likes a sunny, humid environment and avoids scorching sun exposure, so it needs appropriate shading in summer. If exposed to too much sun, the flowers and leaves easily curl. Daily light exposure must not be less than 4 hours, which ensures abundant blooming.
4. Watering
Bicolor jasmine likes moisture and fears waterlogging, so watering should follow the principle of watering when dry and stopping when wet. Watering in summer needs attention: not only must it meet the plant's growth needs, but the air must also be kept humid, spraying clear water on the leaf surface 2-3 times a day. In winter, keep the potting soil dry to prevent frost damage.
5. Fertilizing
During the growing period, apply alum fertilizer water in time, which prevents soil alkalization, avoids leaf yellowing, increases soil fertility, and promotes plant growth. After the flowers fade, apply a dilute cake fertilizer water once, and 10 days later apply a liquid fertilizer mainly of phosphorus and potassium fertilizer once, and while watering, spray a potassium dihydrogen phosphate solution on the leaf surface to promote flower bud differentiation.
The reason bicolor jasmine develops yellow leaves and fails to bloom is still very much related to how flower lovers care for it in daily life. Its flowers are beautiful, but it cannot stand being messed around with, so when growing bicolor jasmine, everyone should still pay more attention to it.
