1、 Cutting propagation

1. Cutting time: Milan cutting is usually carried out from April to June. At this time, the temperature is relatively high, and it is easier to take root after cutting. When the ground temperature is 25-28 ℃, 50-60 natural roots are needed for cuttings. When the ground temperature is 30-32 ℃, it can take root only 40 days after cutting

2. Cuttage treatment: usually select robust Milan plants and cut an annual lignified branch from above as cuttings. The leaves at the top of the branch should be thick, green and full axillary buds. The cut length is about 10cm. Remove the leaves at the middle and lower part, and keep the top 2-3 pieces. The bottom end should be flattened

3. Soil preparation: the matrix of cutting Milan is generally loose and has good drainage, which is conducive to the growth and respiration of new roots. Generally, vermiculite or coarse sand can be used. In order to avoid insect eggs or bacteria, it can be exposed to the sun first, or fried with a waste pot, which can also have the effect of disinfection and sterilization

4. Cutting: use bamboo chopsticks to make a hole in the prepared substrate, and insert the branches into it. The depth is more than one third of the length. Compact the soil by hand to ensure that the matrix fits the cuttings. After cutting, it is necessary to pour water once, maintain good ventilation and avoid direct light

2、 Strip propagation

1. Layering time: Milan layering is mostly carried out from April to August. Like cutting, it should also be selected when the temperature is high and the plant grows faster, so it is easier to take root

2. Branch selection and girdling: select annual lignified branches and girdle them from 20 cm of the bifurcation, with a width of about 0.5 cm. After girdling, you should see the xylem

3. Covering soil for moisturizing: wrap the peeled place with moss or wet soil, and then cover it with plastic film, which can have the effect of moisturizing

4. Split transplanting: generally, the girdling place will take root in about two months, but it cannot be transplanted immediately. It usually takes half a year to separate it, and then it can be planted in the upper pot
