Growth habits of Colored Leaf Grass

Coloured leaf grass is a kind of flower with strong adaptability, which can also be seen in many places in our country, especially in the south, where gardens are often cultivated, and the main cultivation bases are Jiangsu, Zhejiang, Anhui and other places. Thermophilic plants, strong adaptability, winter temperature is not less than 10 ℃, summer high temperature with a little shade, like plenty of sunshine, sufficient light can make the leaves bright.

The Propagation method of Colored Leaf Grass

1. Sowing: it is mostly used for varieties with the same plant quality after sowing, and the suitable temperature is 18 ℃, both in spring and autumn. Sufficient light is needed when germination, keep the breeding sand bed wet, germinate about 2 weeks after sowing, when there are 4 strong seedlings, they can be transplanted to a small basin with a diameter of about 10 cm, and when the seedling leaves cover the basin, it can be planted in a large basin with a diameter of 20 cm and 23 cm. The germination rate is high and the seedlings emerge neatly.

2. Cutting: the varieties with high survival rate and easy variation of sexual reproduction quality can be propagated in four seasons as long as the temperature is suitable, which should be carried out from May to June. Excellent plants with bright colors were selected and cut with softwood. Cuttings are 8 to 10 centimeters long, and loose and fertile coarse sand is the best for breeding soil. Two leaves in the lower part of the cuttings were removed, and the depth of cuttings was about 1 / 3 of its length. Pay attention to shading after insertion, can be placed in a cool place to maintain, keep the basin soil moist, when the temperature is about 20 ℃, about 10 days can take root, and then 2 weeks can be transplanted into the basin.

Water insertion Propagation of Colored Leaf Grass

1. Container: the color leaf grass cutting container can be a jar, or you can cut off the upper part with a mineral water bottle and fill the lower part with fresh water. The container must be clean, the water quality must be clean, and it is best to take a large cola bottle to store water for more than one day for cutting and follow-up management.

2. Cuttings: when the main branch of coloured leaf grass or the side branch that passes through the heart has 4 nodes or about 10 cm in length, select the thick stem, leaving only 1 to 2 opposite leaves at the base, cut off the upper part, the cut should be smooth, there is no wound of extrusion and tear. Then cut off the lowermost pair of leaves of the cuttings, concentrate on the base of every 3 to 5 cuttings, bundle them together with white thread pine, and wait for water insertion.

3. Management: generally, it is best for cuttings to enter water from 3cm to 4cm from the mouth of the bottle, and then place it at the place of scattered light, pay attention to changing fresh water (water storage) every 2 to 3 days, and pay attention to replenishing the falling water level in the bottle due to evaporation every day. Generally, under the condition of 18 ℃ to 25 ℃, white root can be seen in 7 to 10 days.

4. Potting: the adventitious root of colourful leaf grass is easy to grow outside the stem node, and the straight and sturdy stem will also sprout, which provides conditions for cuttings to take shape as soon as possible. When it is seen that there are several 1 cm to 2 cm adventitious roots at the base of the cuttings, they can be put on the pot or planted in time. Pay attention to careful operation, do not damage the root system, generally in the shade of flowers for about 10 days, you can enter the normal management.

How to raise potted colored leaf grass?

1. Soil: potted colored leaf grass requires sandy culture soil rich in humus, loose and fertile, good drainage and air permeability.

2. Watering: the water demand of colourful leaf grass is to keep the basin soil and environment moist and moderate, avoid drought and prevent waterlogging, so as to avoid dehydration and discoloration of leaves and soft rot of root system.

3. Sunshine: when the light is soft and sufficient, the leaf color is brilliant, but it is avoided that the leaf surface is rough and loses glossiness due to the strong light in the clear sky in midsummer. And in the shady environment, the leaf color is not bright.

4. Temperature: the color leaf grass likes the environmental conditions of warm and humid climate and fresh air, the suitable indoor temperature in winter is 20 ℃ to 25 ℃, the lowest overwintering temperature can not be lower than 10 ℃, the leaves turn yellow and fall off when the temperature is too low, and the plants below 5 ℃ die.

5. Fertilization: the requirement of colourful leaf grass for fertilizer is not high, and the thin fertilizer based on nitrogen fertilizer is applied once or twice a month in the growing season.

6. Pruning: the color leaf grass should pick the heart many times in the seedling stage to promote the lateral branches and make the plant shape full. After flowering, 2-3 nodes of the lower branches can be retained, the rest can be cut off and new branches can be reissued.

7. Insect pests: Colored leaf grass is prone to quenching disease in its seedling stage, so attention should be paid to the disinfection of sowing soil. Leaf spot disease is harmful during the growing period, so spray it with 50% topiramine wettable powder 500 times. In indoor cultivation, shell insects, red spiders and whitefly are easy to occur, which can be controlled by 1000 times of omethoate EC.
