The Culture method of Colored Leaf Grass

Colorful leaf grass is also known as colorful thistle, old and young, five-colored grass, brocade perennial, etc., which belongs to perennial herbaceous foliage flowers of Labiatae. Due to different varieties, there are various markings such as yellow, red, purple, orange, green and so on. They are often used in flower beds, venue, theater layout patterns, and can also be used as the matching leaves of flower baskets and bouquets. Let's take a look at the breeding methods of colored leaf grass.

Growth habits of Colored Leaf Grass

Colourful leaf grass is a kind of flower with strong adaptability. It can also be seen in many places in China, especially in the south. Gardens are often cultivated in various parts of our country, 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: coloured leaf grass is generally carried out in the greenhouse in March, half-mixed with fully mature humus soil and plain sandy soil into the seedling basin, the seedling pot containing fine sand soil is soaked in water, and then soaked according to the sowing method of small seeds, slightly covered with thin soil, covered with glass plate or plastic film to keep the basin soil moist, water supply and management protection. The optimum temperature for germination was 25 ℃ to 30 ℃ and germinated in about 10 days.

2. Cuttage: it can be carried out all the year round and is easy to survive. Can also be combined with plant coring and pruning for tender wood cutting, cut full branches, cut off about 10 cm, insert into the clean disinfection of the river sand, the part of the soil must often have leaf nodes rooting, shade maintenance after cutting, keep the basin soil moist. When the temperature is higher, it will take root faster. During this period, the basin soil must not be too wet to avoid rotting roots. It will take about 15 days to root and survive.

3, water insertion: colourful grass water can be inserted into half a cup of cool plain water, cuttings select 2-3 nodes in the middle and upper part of the branches, remove the lower leaves, put them in the water, and plant them in a pot when the white water roots grow to 5-10 mm.

The Culture method of 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. Insect pests: Colored leaf grass is prone to quenching disease in its young 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.

7. 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.
