How do bamboo and cypress leaves turn yellow? how to water bamboo and cypress (how often)

There are many possible reasons for the yellowing of bamboo and cypress leaves, most of which are caused by improper breeding, such as lack of water, lack of fertilizer, insufficient light, and so on. Therefore, in the face of some symptoms of bamboo and cypress, we need to calmly think about why there is such a phenomenon, which can be compared with the correct culture methods, so as to choose targeted solutions.

What if the leaves of bamboo and cypress turn yellow?

1. Bamboo and cypress are short of water for a long time

The specific performance is that the leaf tips or edges of bamboo and cypress are withered and dry, while the old leaves are withered and yellow and fall off from the bottom up.

Solution: timely watering to keep the soil moist, but avoid stagnant water, and it is appropriate to water thoroughly when the topsoil is slightly dry.

2. Bamboo and cypress lack of light.

If there is no light for a long time, the leaves will turn yellow and white, and the branches are slender and not easy to blossom.

Solution: after gently rinsing the leaves, scatter the plant as far as possible to the range of better light.

3. The leaves of bamboo and cypress turn yellow due to the high temperature.

When the temperature exceeds 35 °C, the leaves or tips of bamboo and cypress will be yellow, dry or spotted.

Solution: move the bamboo and cypress to a cool place for maintenance to avoid direct glare.

4. Low temperature causes yellowing of bamboo and cypress leaves.

When the temperature is about 10 °C, the bamboo and cypress will enter the dormancy period, and if the temperature is lower than 2 ℃, it is easy to frostbite or freeze to death.

Solution: move the bamboo and cypress to a warmer place indoors to prevent the cold wind.

5. Bamboo and cypress are short of fertilizer for a long time.

Without meeting the water and fertilizer needs of bamboo and cypress, it is not easy to keep the leaf color of bamboo and cypress thick green, and the leaf tip is easy to yellowing.

Solution: apply some acidic fertilizers in time, and irrigation solution is the best, so as to apply less frequently.

6. Occurrence of diseases and insect pests of bamboo and cypress

Red spiders appear in bamboo and cypress leaves, or anthracnose, leaf spot disease, shell insects will cause local scorched yellow leaves.

Solution: for red spiders, triclofenac and Nisolan can be sprayed; shell insects can be sprayed with chlorpyrifos and methophos; for anthracnose and leaf spot, carbendazim and carrageenan can be sprayed.

How to water bamboo and cypress

1. How to water in different periods

Spring and summer are generally the peak seasons of plant development, and because of the high temperature, transpiration is also strong, so it needs more water. So keep the basin soil wet and don't let it get too dry. If you can't see clearly with the naked eye, you can touch the topsoil with your hands and water it if the hair is dry; if the surface is wet, then there will be no shortage of water inside, and there is no need to water at this time, otherwise it is very likely to be excessive.

The average amount of water needed in autumn can be irrigated every two to three days to keep the soil slightly wet, enough to supply plants.

Needless to say in winter, most plants generally have no need for water, so it's best to stop watering at this time. Or if you see that the potted soil is too dry or the leaves of the plant begin to wilt, water it properly, about once a week.

2. Points for attention

In order to prevent the leaves from drying up and falling in a dry environment, spray some water around the plants or spray some water on the leaves. Of course, this can also wash away the dust around the plant, making the plant look cleaner and more beautiful.

In summer, the temperature is high in the afternoon can not be watered, generally speaking, the morning and evening is more appropriate.

According to the degree of wetness of plants, it is important to understand that too dry and too wet are bad for plants. The most important thing of watering is the adjustment of "degree".

How to fertilize bamboo and cypress

1. Fertilizer requirements of bamboo and cypress.

As we can see the robust appearance of bamboo and cypress, its adaptability is also excellent. It can live in very poor places and does not need too much fertilizer. However, proper fertilizer can provide flowers with nutrients that cannot be absorbed from the soil, so it still makes sense.

2. What fertilizer should be applied

Natural animal droppings are the best, with no side effects and no harm to the surrounding environment.

If you buy fertilizers on the market, you can choose urea or other fertilizers with balanced nutrition.

3. Different treatment methods in different periods.

When the plant is in the seedling stage, there are more requirements for nutrients, in order to make it grow more quickly and steadily, we should apply more fertilizer; when it adapts to the surrounding environment and can grow steadily, we can appropriately reduce the number of fertilization.

In spring and summer, when plants regenerate and grow faster, fertilizers can be applied every half a month or 20 days with some urea (0.2% concentration is appropriate), or animal waste.

In autumn and winter, especially in late autumn and throughout winter, plants enter a period of slow development, with almost no fertilizer applied.

What if the roots of bamboo and cypress are rotten?

1. Scientific watering. Needless to say, although this plant likes to be moist, it is afraid of waterlogging, so it is necessary to strictly control the amount of watering. Generally speaking, spring and summer should be watered a little more, so that the basin soil is not dry. From late autumn to winter, the quantity and frequency must be strictly controlled.

2. If it is caused by diseases and insect pests, this is not very common, because bamboo and cypress diseases and insect pests are generally aimed at leaves. If there is such an accidental situation, it is easier to deal with, just buy a special medicine.

Watering and fertilization are the two most important factors in the process of plant survival, water is the source of all things, watering is the basis to ensure plant survival, fertilization is to provide plants with due nutrients, compared with other elements, these two are the basic principles of plant breeding, so we must pay attention to it.
