How do evergreen coniferous trees propagate? How to apply fertilizer correctly? How should I water it?

The tree shape of Luohan pine is quaint, the combination of seed and seed stalk is strange and lovable, and many temples and houses are planted in the south. Can be planted in front of the door, isolated planting in the atrium, so do you know how to reproduce Luohansong? How to apply fertilizer correctly? How should I water it?

First, how to reproduce Luohansong

Sowing season

The sowing of Pinus elliottii takes place in August every year. It can be carried out after the seeds are harvested in August.

Sowing and maintenance

The growth of sowing seedlings is slow, it is necessary to keep the basin soil moist, and shade maintenance should be carried out in midsummer. Fertilization is mainly light fertilizer, too high concentration is easy to burn seedlings. When transplanting into the basin, the seedlings need to carry soil.

Propagation method of Pinus elliottii: cutting

Tender wood cuttage

Softwood cutting refers to the cutting method of using semi-mature branches as cuttings in the growing season of seedlings, which is mainly suitable for evergreen and semi-evergreen woody flowers.

Softwood cuttings are generally carried out from mid-late May to early July in the first half of the year, and from mid-late August to mid-late September in the second half of the year. Seedlings planted in the first half of the year should pay attention to prevent high temperature burns and diseases. Seedlings planted in the second half of the year should pay attention to the middle and later stage of heat preservation and anti-freezing, the time to uncover the shade net is in late November, and the time to uncover the shade net in dry years can be extended to late December.

Hardwood cuttage

Hardwood cutting refers to the method of cutting the sturdy branches completely lignified in the previous year during the dormant stage from February to March in early spring when the sap has not yet flowed.

Hardwood cuttings are not as easy to root as softwood cuttings, so some measures to promote rooting need to be done, such as applying some rooting powder to the incision and then inserting it into the pot.

Hardwood cuttings in early spring should pay attention to improve the soil temperature and control the temperature of the growing environment.

2. How to fertilize Luohansong correctly

1. What kind of fertilizer should be applied

Luohansong should use cake fertilizer, manure and other organic fertilizer, fertilization time should be carried out in spring, apply 1-2 thin cake fertilizer water, do not apply more thick, do not need fertilization in autumn, otherwise sprout autumn buds and be vulnerable to freezing damage.

2. Fertilization method

Luohan pine also needs to supplement nutrients. Luohan pine does not like thick fertilizer. Mature organic liquid fertilizer can be used in the growing season with a concentration of 1:6, 1:8, 1:10, once every ten days and a half month, and water should be irrigated the second day after fertilization. This is beneficial to root absorption. Luohan pine cultivated in the open field can apply organic liquid fertilizer with a concentration of 1:4 before spring shoot germination and after autumn shoot growth. Dig ditches during application, cover the soil after application, and irrigate once the next day, usually without fertilization. If there is no rain after a long drought, irrigation is needed. If in order to enjoy its green leaves, no matter potted or planted on the ground, you can use 1:15 concentration to add a small amount of liquid fertilizer to the water every half month to irrigate the flowers with muddy water.

The rarefied liquid fertilizer dominated by nitrogen fertilizer can grow well when it is applied 2 or 3 times in spring and autumn respectively. Water should be watered once the next day after fertilization, which is beneficial to the absorption of roots.

How should Luo Hansong be watered

1. Method of watering

Luohansong in the cultivation of water and fertilizer requirements are actually not strict, Luohansong is a relatively strong vitality of plants, it is more resistant to drought, but in potted plants, watering still needs to master certain methods. First of all, potted Luohansong needs to have a certain drainage capacity, be careful not to accumulate water for a long time, otherwise it will lead to its rotten roots. When watering Luohansong, you need to keep the soil slightly dry, which is what flower friends say is three percent wet and seven percent dry. Follow the principle that you'd rather be dry than wet, and don't overwater it when watering. The second is in summer, because the summer temperature is high and the light is strong, so evaporation will be very exuberant, at this time watering should be more, the soil can not be too dry, lest the leaves wither and yellow.

2. Points for attention in watering

When watering Luohansong, you need to pay attention to the frequency of watering. The specific watering time should be determined according to the actual growth of Pinus elliottii, including the dryness of flowerpots and soil. Basically, it will be watered when the water evaporates and the basin soil dries. If the water evaporates too quickly, you also need to spray water frequently. Water must be thoroughly watered. When watering Luohansong, it is best to water along the edge of the flowerpot, that is, along the inner wall of the outside of the flowerpot. When watering, you should master the amount of watering.
