What should I do if the leaves of Ruixiang flowers are yellow, what happens when the old leaves of R

Reason: If there is a certain change in the living environment, and the temperature drops suddenly, it will make the plant unbearable, damage its capillary roots, and make the leaves grow yellow. Too hot and humid temperatures can also affect it.

Solution: Pay attention to the changes in the weather, if the temperature drops greatly, move it indoors for maintenance, and put it in a well-lit place. If the surrounding temperature becomes high, put it in a well-ventilated area to promote air circulation and reduce the temperature of the plants.

Reason: It is not resistant to moisture, can not withstand waterlogging, if the application of water is not according to the growth of the plant, excessive watering will lead to water accumulation in the potting soil, the root system can not bear it, causing the leaves to turn yellow, in serious cases will fall off and rot.

Solution: Put the potting soil in a ventilated place to speed up the evaporation of water and reduce the degree of waterlogging. After that, the plants are watered moderately, and the frequency is determined according to the season and climate.

Cause: The application of fertilizer exceeds the actual demand, causing fertilizer damage, which restricts the growth of the plant and causes the leaves to turn yellow and fall.

Solution: Apply according to the different conditions of plant growth, the dosage should be a little less, and the concentration should not be too high. If it causes fertilizer damage, it needs to be poured with water to drain it.

1. Watering too much.

In fact, this is the most obvious reason, many flowers appear yellow and yellow phenomenon, most of them are caused by overwatering, we have also said above, Ruixiang absorbs water very slowly, usually do not need to water often, and in the spring the requirements for water are not high, and then encounter rainy weather, then do not need to water. However, as the weather gets hotter and hotter, Ruixiang's requirements for moisture will become higher, especially when the temperature is above 20 degrees, it is even more necessary to maintain sufficient moisture, and if the temperature is too high, you also need to spray some water around Ruixiang, which can play a moisturizing role.

2. Inferior soil.

If the soil used is not permeable, then it is difficult for the pot to survive, because the water poured can not flow to the roots, and the surface will be formed into soil clods for a long time, and the watering can only stay on the surface of the pot, and the roots of Ruixiang can not absorb water, and the leaves will wither. Therefore, we will not dispose of some old soil and try not to use it again, because there are not many nutrients in it, and it is not suitable for planting flowers at all.

3. Pests. As long as it is a plant, there will be some pests and diseases, in fact, these diseases are very common, when breeding flowers outside, insect pests often haunt the flowering period before a period of time, because the buds are relatively immature, they like to stay in some small cracks and grow slowly, so when raising flowers, we need to observe more to see if there are any small insects. There are insects on your own Ruixiang flowers, and you need to use rent-killing round insect agents to kill insects, don't use too much when spraying, and don't send away the flowers with insects.

1. The light is too strong.

Although Ruixiang likes the sun, it is not resistant to exposure to the sun, especially in summer, the sun is very strong, if it is directly exposed to the sun outside, the leaves will be sunburned, dry and fall off.

Solution: Move the Ruixiang plant to the scattered light or pull the shade net to shade it, and the oak Zen can see the sun in the morning and evening.

2. Overwatering.

Ruixiang is afraid of waterlogging, and if it is watered frequently, the potting soil will be in a state of stagnant water for a long time. Then the root system will not be able to breathe normally, and over time, the root system will rot. The leaves are partially unable to absorb water, resulting in yellow leaves and leaf loss.

Solution: Pause watering and move the plants to a ventilated place. So that the water in the basin can be quickly dissipated. As long as the root rot of the plant is mild, it can slowly return to normal after a period of time. During the recovery period, wait for the potting soil to dry before replenishing water.

3. The temperature is too low.

Ruixiang has poor cold resistance, and when the temperature is lower than 5 degrees in winter, the leaves will be frostbitten, and the leaves will turn yellow and hydrate.

Solution: Move the plants indoors to keep warm, and remove the yellow leaves.

4. Soil alkalization.

Ruixiang likes to grow in slightly acidic soil, such as the alkalizing of Liangchen fruit pot soil or long-term irrigation with alkaline water, Ruixiang will have poor growth and yellowing of leaves. In severe cases, the entire plant will die.

Solution: Use ferrous sulfate solution to water, and use it several times in a row can effectively improve the condition of yellow leaves. Ferrous sulfate or organic fertilizer is regularly used to improve the alkaline soil and make the soil more suitable for the growth of Ruixiang.

If the new leaves are yellow, most of the caution is caused by the alkaline soil, you can water the ferrous sulfate dilution solution once in about 10 days, or you can use orange peel to soak in water, the effect is good. Of course, it is better to store more rainwater for the best effect. Usually pay attention to ventilation, semi-shade, this filial piety does not need to urge flowers, it is best to go with the flow.
