Causes of drying and discoloration of leaves of Ji pineapple and its solution

Ji pineapple is a very beautiful plant, its leaves are unique, red, look particularly beautiful. But the leaves of Ji pineapple cultivated by many friends are brightly colored at first, and the leaves begin to fade and become dry. How is this going on? How to solve the problem? The following editor will explain the reasons and solutions to you in detail.

Causes of drying and discoloration of leaves of Ji pineapple and its solution

1. Reasons:

Ji pineapple leaves were originally purplish red, turned green because of the lack of sunlight, plants can not carry out photosynthesis, lack of lycopene and chlorophyll, so the color changes gradually.

If the indoor location is too dark, the markings on the leaves will gradually disappear, and the leaf color will become dim and lose its ornamental value.

In addition, too strong direct light will burn the leaves and miscellaneous spots will appear on the leaves.

Ji pineapple is not hardy, so the lower the temperature in winter, the darker the leaf color will be.

The leaf tip dries up because the summer air humidity is low, the evaporation is relatively large, and the leaves are easily short of water, which leads to the leaf tip drying up.

2. Solution:

Ji pineapple likes the semi-overcast environment and is suitable for growing under the condition of 20 ℃-25 ℃. It should be placed near the sunny windowsill and can receive up to 4 hours of direct sunlight every day, but avoid strong sunlight.

The position of Ji pineapple should be changed according to the change of season. The lowest room temperature in winter should not be lower than 15 ℃, and Ji pineapple is vulnerable to freezing injury when it is lower than 10 ℃.

During the peak growth period, Ji pineapple can make its leaves bright by applying organic liquid fertilizer once every 10 days and alum solution once or twice a month. If you don't apply more nitrogen fertilizer in daily life, the leaf pattern will become dim.

In order to prevent the leaf tip from drying up, to keep the basin soil moist, spray water to the leaf surface once or twice a day, and the cup-shaped part of the leaf seat can be filled with water.

The Propagation method of Ji Pineapple

1. Sowing and reproduction

The seeds of Ji pineapple need artificial pollination and are sown in flowerpots from late April to mid-May and can germinate within two weeks when the ambient temperature is kept at 25 ℃. The disadvantage of this method is that the growth of sowing seedlings is too slow and it takes about three years to grow up.

2. Cuttage propagation

Cut off the leaf axis next to the mother plant, pay attention to cut off from the root base, while retaining the first three leaflets, and then insert the leaf axis into the prepared sand bed and maintain it in a cool environment of 30 ℃ while maintaining high humidity. This method can take root in about 3 weeks, divide seedlings in 7 weeks, and propagate faster.

3. Ramet propagation

It is a commonly used method nowadays, which is best carried out after the soil is thawed in early spring (February and March). After the mother plant is taken out of the flowerpot, the root is cut and then planted. Ramet propagation is especially suitable for herbaceous flowers with tufted characteristics, and the advantage of this method is that the survival rate is high.

Insect pests and control methods of Ji pineapple

1. Insect pests:

The insect pests of Ji pineapple are seriously damaged by pink scale and shell insects. Pink scale is a small juice-sucking insect with white sticky powder outside the body, which can harm crops, fruit trees, gardens, forests and pastures. Scale insects will absorb the sap of plants, and in serious cases, it will cause death of the whole plant, and its secretions may also cause coal fouling disease, which is very harmful.

2. Prevention and control methods:

For pink scale, if it is not a particularly serious infection, you can get rid of it by hand, spray it with strong water (be careful not to hurt Ji pineapple), or rinse the plant with water and methylated alcohol 1:1 solution. This can not only wash away the bugs, but also kill those that can not be washed away.

In the process of breeding Ji pineapple, it is found that there are shell insects on individual leaves, which can be gently brushed off with a soft brush, or combined with pruning to cut off insect branches and leaves. It is required to brush clean, cut clean, focus on burning, do not throw.

Growing environment

Ornamental pineapple likes warm, humid, sunny environment. Only in bright light can it blossom normally and get the most beautiful leaves, but it is still necessary to prevent direct sunlight at noon in summer. The suitable growth temperature is 20-30 ℃ in summer and 15-18 ℃ in winter. It is difficult to grow when it is lower than 10 ℃, and the lowest growth temperature is 5 ℃ at night. The soil is mixed with decaying leaf soil or peat soil with neutral or slightly acidic sandy loam.

Now we all know how to solve the discoloration of Ji pineapple. In fact, for the leaves become dry, it is generally caused by the lack of moisture, at the same time, for Ji pineapple, the lack of sunlight will also cause the leaves to fade and change color, so we must regularly let him bask in the sun!
