"evergreen vine" green pineapple culture methods and matters needing attention! What if the leaves turn yellow? When is the best time for cutting?

Green pineapple is an evergreen vine, which belongs to the unicorn leaf genus of Araceae. It can be cultivated in soil or in water. Properly maintained, the leaves are large and green, and they are very suitable for placing on the windowsill of the study. Do you know how to raise green pineapple? Let's take a look at the breeding methods and points for attention of green pineapple.

Culture methods of green pineapple

Two culture methods of green pineapple

Soil culture: green pineapple is easy to raise, and the preparation work of soil culture is to select the soil suitable for green pineapple growth. The soil is as fertile as possible, and most of the nutrition of green pineapple comes from soil. Try to choose some soil in the field, mix the soil with animal droppings, and put some fine dead leaves in the soil. Green pineapple likes soft soil, withered leaves and feces play a role in increasing soil fertility, softness and ventilation.

Hydroponic culture: hydroponic green pineapple is one of the very good indoor decoration hydroponic plants, climbing vine foliage flowers. The stem of the radish is soft and the leaves are delicate. Hydroponic green pineapple is extremely shady, and can be placed all the year round in the sunny place indoors. In darker rooms, it should be moved to the environment with strong light every semimonthly to recover for a period of time, otherwise it is easy to make the internodes grow and the leaves become smaller.

Light and temperature of green pineapple

Illumination: the original growth condition of green pineapple is in the forest sheltered by towering trees, the positive direction is not strong. However, in the north of autumn and winter, in order to supplement the deficiency of temperature and photosynthesis, its illuminance should be increased.

Temperature: in the north, the green pineapple can survive the winter safely when the room temperature is more than 10 ℃. When the room temperature is above 20 ℃, the green pineapple can grow normally. In general, it is not a big problem for families to reach this temperature, we should pay attention to avoid excessive temperature difference, and at the same time, we should also pay attention to the leaves not close to the heating equipment.

Matters needing attention in the culture of green pineapple

Shaping and pruning of green pineapple

People rely on clothes and horses on the saddle, while succulent foliage plants often need to be trimmed to maintain a beautiful shape.

Green pineapple is very popular among foliage plants. Of course, you should pay attention to shaping and pruning it.

4-5 plants are planted or cut directly in each pot, and a brown column is set up in the middle of the pot to facilitate the winding and upward growth of green pineapple. Plastic pruning is carried out in the spring. When the stem vine crawls all over the brown column and the tip exceeds the brown column 20cm or so, cut off the stem tip 40cm of 2-3 plants. When new buds and new leaves sprout after truncation, cut off the stem tips of other plants.

If the whole plant or the lower half of the plant is defoliated due to freezing in winter or other reasons, the half of the stem can be cut short by 1 / 2, and the other half by 2 / 3 or 3 / 4, so that the cut mouth is staggered so that the new leaves growing meters under the cut can be quickly covered with brown columns.

Pay attention to the yellowing of green apple leaves

Generally, the newly bought green apple has an adaptation period of about 1 month to the new environment, and the bottom yellow leaves are normal, but remember: yellow or dead leaves should not be directly peeled off, but should be cut off from the middle of the petiole, so as to avoid direct stripping causing too much water loss and increased wounds. as a result, the upper leaves will turn yellow.

Green pineapple is not afraid of darkness, but a very dark environment can also cause yellow leaves, which can be moved regularly to places with good light; at the same time, it can not be exposed to the sun, too much exposure in strong light will not only cause yellow leaves to fall, but also lead to the death of the whole plant. Avoid strong light in summer.

Common diseases of green pineapple

Common diseases of green pineapple: anthracnose, root rot, leaf spot.

These three common diseases of green pineapple are harmful to plant leaves and affect the ornamental value. In the process of maintenance, we must observe carefully and find that the disease spots on the leaves should be cleaned up in time and sprayed in time.

Several reasons for the yellowing of green apple leaves

1. Environmental issues:

Many people will find that the leaves at the bottom of the green apple just bought begin to turn yellow and black in a few days, because the green apple has come to a new environment and needs to adapt, so the old leaves will turn yellow and black, the environment changes abruptly, and the temperature, humidity and light suddenly change too much, or the leaves turn yellow when the roots are hurt by changing pots.

Specific manifestations: the new leaves are normal, while the old leaves turn yellow and black.

Solution: there is no need to worry about this situation, measures can be taken to reduce the degree of change in the environment, and so on to adapt to it, generally a period of time will be normal.

Second, the problem of sunshine:

Green turnip negative plants, like hot and humid environment, avoid direct sunlight, if long-term placed in the sun direct balcony, windowsill, it is easy to have yellow leaves.

Specific performance: the sunny part of the leaves appear macula, wilting and wilting.

Solution: place in direct sunlight, ventilated place, and appropriate watering, ease for a period of time can be normal.

3. Ventilation:

If the green pineapple is placed in an unventilated and light-free place for a long time, it is easy to turn yellow in the whole plant, which is due to the fact that it is unable to synthesize chlorophyll because there is no light and no ventilation.

Specific performance: new leaves and old leaves are yellow

Solution: move to a place where ventilation is not dark and you can recover.

4. Watering:

Green pineapple prefers hot and humid environment, but it should not be watered too much, especially in autumn and winter, too much or too little watering will lead to yellowing of leaves.

Specific performance: if the leaf tip or edge withered, the new leaf growth is normal, the old leaf withered and yellow shedding is underwatering; if the leaf surface is dark yellow, no luster, the new leaf tip atrophy is not long, is too much watering.

Solution: increase or decrease watering appropriately.

Fifth, the issue of fertilization:

The yellowing caused by excessive fertilization or excessive concentration is shown in the dry brown appearance at the tip of the new leaf, the general leaf surface is thick but not glossy, and the concave and convex leaves are not stretched, and the old leaves are scorched yellow; if there is a lack of fertilization, the color of the surface becomes lighter, first transitions to light green, and then gradually turns yellow.

Specific performance: when fertilizing too much, dry brown appears at the top of the new leaf, the leaf surface is thick but not glossy, and the concave and convex does not stretch; the lack of fertilization shows that the color of the tender leaf becomes light, yellow or light green, while the old leaf is relatively normal or gradually changes from green to yellow.

Solution: when you apply too much fertilizer, you can consider changing the pot soil; if you lack fertilization, you can pay attention to fertilization.

Sixth, the problem of rotten roots:

Rotten root is also a cause of green apple yellowing, generally causing green radish rotten root problem is the cause of pot soil and watering.

Specific performance: the color of tender leaves becomes light, yellow or light green.

Solution: cut off the rotten roots, smear the wound with plant ash, and then change the soil and return to the basin. Pay attention to the fact that there is no stagnant water in the basin, and the bottom had better be sprinkled with plant ash.

When is the best time for green pineapple cuttage

Suitable cutting time:

Green pineapple cultivated indoors can be cut all the year round, but it is best from April to August.

Unsuitable cutting time:

When the temperature is lower than 15 degrees, the growth activity of green pineapple is affected, and cutting is not recommended at this time.

Key points of cutting:

In order to improve the cuttage survival rate of green pineapple, when selecting cuttings, we can choose branches with obvious aerial roots, which can take root quickly.

Green apple cuttings

Prepare nutritious soil, 8 parts of coconut bran, 0.5 parts of perlite and 1.5 parts of garden soil.

Choose a strong vine with air root as the cutting mother, with air root can greatly shorten the rooting speed, a pair of sharp scissors.

Cut the branches one by one, each cutting branch about 10cm, leaving 1-2 leaves, 1 bud point, the cut as far as possible to avoid the air root, the lower end cut into an oblique angle of 45 degrees, it is best to be smooth.

Insert the branches vertically into the soil, leaving a certain distance between each branch, filling the whole flowerpot.

After the branches are inserted, water them thoroughly and place them in a cool and ventilated place. It is necessary to keep the soil moist and high air temperature. The soil moisture is about 50%, while the air humidity is 80%-90%.

Generally take root after more than 10 days, pay attention to foliar spray and shade on sunny days in summer, pay attention to cold prevention in winter, and manage normally in the basin about 10 days after rooting.

Green pineapple is very strong vitality, even if there are no leaves, as long as there is a bud point, it can also be used as cuttings. The stronger the branches, the faster they sprout! The method is the same as cutting branches with leaves. Two weeks later, the green radish sprouts began to sprout.

Green apple water insert

Select the branch with air root, each cutting branch is about 20cm, leaving 1-2 leaves, 1 bud point, cut as far as possible to avoid air root. Put the cuttings into a hydroponic container and change the water when the water quality is muddy.

The tender stem with single leaf and no air root had better not be used, it is difficult to take root, and it is easy to rot and cause the water body to become worse, so take it out and throw it away.

After a period of time, the branches grow more plump roots, and they can be cultivated in soil or in water all the time.
