Culture methods and matters needing attention of perfume grass

They are propagated by cuttings or by sowing, but if they are cultivated in a greenhouse, it is usually difficult to obtain seeds. The appropriate time for cutting can be carried out in all seasons, but it is better in spring and autumn; indoor cutting is mostly carried out in 2mi-March, and tender wood cutting is carried out. During the rainy season, the stem segments with 2-4 nodes were cut from the strong twigs on the upper part of the plant, and the □ should be about 0.5cm below the node and should be smooth. Remove the lower leaves of the cuttings, leaving only the upper 2-3 leaves. River sand is usually used as cutting medium. The depth of the cuttings is 1PUB3 of the cuttings, gently press around the base after cutting, so that the cuttings are closely connected with sand, pour enough water after cutting, and shade, and then maintain a certain humidity, root for about 3 weeks, and then first transplant to a small pot. Humus soil, sand and garden soil can be selected, and a small amount of grass ash can be mixed well. After 20 days, the pot was turned over and planted in a larger basin. When the seedling grows 7-8 cm tall, the heart is removed. To strengthen fertilizer and water management, it takes about 60 days from cuttage to flowering.

The suitable sowing time in autumn is autumn sowing, and the life span of perfume grass is very short and can only last for one year, so the seeds harvested should be sowed early in order to obtain a higher seedling emergence rate. The temperature is 22 degrees Celsius and sprouts in about 20 minutes and 30 days.

The pot soil should be made of fertile and loose loam with good drainage, 4 parts of garden soil, 3 parts of compost soil, 2 parts of sand soil and 1 part of grass ash. It takes 3 months from seedling to flowering. The root system of the plant is well developed, and the fibrous root grows very vigorously, so it is appropriate to change the pot for two times in order to facilitate the root system development.

After transplanting into the pot. it is necessary to pick the heart in time from the seedlings to promote its branching and more flowering. Those who need to turn over the basin should also pick the heart to make it form a dense and satisfactory plant shape. If you want to cultivate a larger plant type, you can use pillars to support and kidnap, and peel off all its lateral buds to make the branches grow to height. After the stem grows high, the heart is picked repeatedly to make it grow into an umbrella-shaped plant.

Culture methods of perfume grass

Sunshine and temperature

Perfume grass likes the sun, requires sufficient light, lack of light, will make the perfume grass poor growth and will affect the flowering. In winter, it is necessary to put the perfume grass in a sunny place for maintenance; in summer, it is necessary to shade the perfume grass, otherwise it will make the leaves of the perfume grass burn and turn yellow; the light is sufficient in spring and autumn, and the temperature is more suitable, so that the perfume grass can get enough sunshine. The suitable temperature for the growth of perfume grass is between 15 ℃ and 25 ℃. When the summer temperature is more than 30 ℃, the plant will enter a semi-dormant state, the winter temperature above 13 ℃ can continue to blossom, the overwintering temperature should be above 5 ℃, and frostbite will occur at about 0 ℃. Therefore, perfume herbs should be maintained in cool and ventilated places in summer and in sunny and warm places indoors in winter.

Basin soil

Potted perfume grass, the soil can use good drainage of loose and fertile soil, can be garden soil, compost soil, sand and plant ash with the allocation of soil. During the growth of the seedlings, the pot can be changed 1 or 2 times to allow the perfume grass to grow normally.

Water and fertilizer management

Perfume grass likes the moist growth environment. In the peak growth period of spring and autumn, the basin soil remains moist and can be watered once a day; controlled watering in winter, the basin soil should not be too moist, once every 2-3 days; in summer, it can be watered once in the morning and evening to promote growth. In terms of fertilization, vanilla is more fond of fertilizer. After a week on the pot, it can be topdressing. During the growing period, thin liquid fertilizer can be applied once a week, and compound fertilizer can be applied every 3 weeks. In low-temperature winter and high-temperature summer, fertilizer can be reduced or stopped.

Reproduction method

The propagation methods of perfume grass are mainly sowing and cutting, and cutting propagation is commonly used.

Matters needing attention in the culture of perfume grass

Pruning and shaping

After the vanilla is transplanted into the pot, the heart should be picked in time, and it can be more branched and blossom. You can also pick the heart many times to control the plant type of perfume grass.

Diseases and insect pests

With the growth of perfume grass, there may be the phenomenon of plant aging and the harm of shell insects.

The propagation mode of perfume grass

The Cuttage Propagation of Perfume

The propagation of perfume grass is generally carried out by cutting, and the appropriate period of cutting can be carried out all the year round, but the cutting effect is better in spring and autumn.

The cutting of perfume grass can be carried out indoors, and the twigs of perfume grass can be selected for cutting. Indoor cuttage is usually from February to March, select the more robust twigs from the upper part of the plant, retain 2 to 4 stem nodes, cut off the shoots from the plant, and make a smooth cut. When the twigs cut off from the perfume grass are used as cuttings, the leaves of the lower part of the cuttings need to be removed, and the stem retains 2 or 3 leaves of the upper part of the shoots.

To prepare a suitable cutting substrate, clean river sand is generally selected for cutting. Insert the vanilla cuttings into the matrix. Note that the cuttings can be inserted into the sand by 1/3. After cutting, gently press the sand, then pour enough water and shade properly. Keep a certain amount of humidity and temperature, and it will take root in about 3 weeks.

After taking root, the perfume grass can be transplanted to Huanzhong, and the heart can be removed when it grows to about 7, 8cm, and the management of water and fertilizer should be strengthened in the process of maintenance.

Sowing and propagation of perfume grass

Sowing and propagation is also a method of propagation of perfume grass, but the seed life of perfume grass is short, so it is necessary to sow as early as possible after seed harvest.

The sowing and propagation of perfume grass is usually carried out in autumn. The harvested seeds are sown at a temperature of about 20 ℃ and can germinate in about 20 to 30 days. When the seedlings of vanilla grow to a certain height, they can be transplanted and planted.

Common problems and solutions of perfume herb

What if the leaves of perfume grass turn yellow?

One of the reasons why the leaves of perfume grass turn yellow is the problem of drying and humidity. Vanilla likes a moist growing environment. During the exuberant growing season, it is required to keep the soil moist. If it is too dry or too wet, it will cause the leaves of the herb to turn yellow or even fall off. Therefore, vanilla watering, the need to control moisture, to avoid leaf yellow.

The leaves of perfume grass turn yellow, and it may also be caused by light and temperature.

Generally in summer, strong light and high temperature, it is easy to make the leaves of perfume grass withered and yellow, the need to put perfume grass in a cool place of ventilation, shading and cooling maintenance.

What about the occurrence of diseases and insect pests in perfume grass?

The disease of perfume grass is less, and it is easy to be damaged by shell insects in the process of maintenance, so it needs to be prevented and controlled in time.

What about the aging of perfume plants?

After several years of cultivation, there will be the phenomenon of plant aging, the stem gradually lignified, the leaves at the base will gradually fall off, the position of flowering will continue to move up, and the lower part of the plant will become bald. At this time, the plants of vanilla are not beautiful because the branches are soft and the old plants are scattered, so they are generally used as annual or biennial plants. after the plants are aged, they can be cut by cutting. regenerate new plants.

What about the rotten roots of perfume grass?

The most obvious reason for the rotting root of perfume grass is that it is overwatered and the soil is too moist, which leads to root rot. This needs to be done from watering, reasonable watering, and to strengthen the ventilation of the environment. In addition, the rotting root of perfume grass may also be due to the invasion of insect pests, so we should pay attention to the prevention and control of diseases and insect pests.
