1. Sowing: the sowing and propagation of Pinus elliottii can be carried out in August, usually in the open field seedbed, with picking and sowing, covering with straw, shading, keeping the substrate moist, and covering with plastic film to prevent freezing in winter.

2. Cuttage: the cuttage propagation of Pinus elliottii can be carried out in spring and autumn, the spring is in the middle of March, and the one-year-old stout dormant branches are selected as cuttings. Autumn is planted from July to August, and semi-lignified green branches are selected as cuttings.

Luo Hansong upper basin shape

The main results are as follows: 1. upper basin: Luohansong is usually put on the basin before germination in spring, and the basin soil should use slightly acidic sandy loam with loose texture and good drainage. As the posture of Luohansong is simple and elegant, it is appropriate to choose purple sand basin or glazed pottery basin for cultivation, and the shape of the basin is determined by the shape of the tree.

2. Styling: the styling of Luo Hansong is mostly carried out in the dormant period, mainly in Panzha, supplemented by pruning. Because the branches of Luohansong are soft, easy to be tied, and can be trimmed, there are various shapes, such as curved dry type, oblique dry type, horizontal cloud type, cliff type and root type, etc., and the branches and leaves can be trimmed into flaky or steamed bread shape.

Bonsai maintenance of Luohansong

1. Venue: Luohansong should be placed in a warm, humid and well-ventilated place in summer and indoor above 5 ℃ in winter, but the temperature should not be too high so as not to affect its dormancy. Family potted Luohansong should be maintained in an outdoor ventilated place all the year round, not indoors for a long time, otherwise the leaves will fall off and die, the high temperature in summer should not be exposed to the sun, and should be kept in a semi-shady place for maintenance.

2. Watering: Luohansong likes moist soil, so it should be watered frequently during the growing season to keep the basin soil moist, but it can not be watered in the basin, and it is often sprayed to the leaves or the ground in summer. Watering should be fully watered to keep the leaf color bright, and the moisture in autumn and winter can be reduced appropriately.

3. Fertilization: Luohansong only needs to apply nitrogen-based topdressing twice in spring and autumn, without excessive phosphorus and potassium fertilizer. It is not suitable to apply more fertilizer to the molded lohan pine. Usually in the growing season, mature thin liquid fertilizer is applied every other month, and no more fertilizer is applied after autumn.

4. Pruning: Luohansong should be pruned frequently to maintain the shape of the tree. It is best to remove the buds in time when blooming so as not to consume nutrients. For the modeled bonsai, attention should be paid to heart-picking and pruning to prevent branches and leaves from growing, so as to maintain the original posture. Pruning and heart-picking work is best carried out during the growth period of spring and autumn.

5. Turning the basin: Luohansong usually turns the basin every 2-3 years, usually from March to April.

6. Insect pests: Luohan pine is mainly harmful to leaf spot and anthracnose, and is sprayed with 50% methyl topiramate wettable powder 500 times. Pests are harmful to shell insects, red spiders and coir moths, which can be sprayed with 1500 times omethoate EC.
