1、 Planting method

Prunus deltoides is mainly cuttage. Cutting in the north is mainly in May and June, and 20-30 ℃ is the appropriate temperature. Select annual lignified branches, cut about 20cm, remove the leaves near the low end, and leave 2-3 leaves. After the treated branches are inserted into the sand basin for 4-6cm, cover them with glass for insulation, and water them thoroughly for the first time. Let the cutted plants be placed in a ventilated and cool place. Sparse light can be seen within 15 days. After rooting for about a month, they can be fully illuminated. It can bloom after two years of culture

2、 Maintenance measures

1. Light: do not see strong light before rooting. You can see light all day after one month

2. Cover the air vent with moisture film if the weather is good. In the evening, the ventilation can be opened and re covered after spraying water

3. Fertilization: when cutting, fertilization can be carried out outside the root. One thousandth of potassium dihydrogen phosphate aqueous solution can be selected and sprayed once every 10 days

4. Upper basin: refine the surviving seedlings under strong light and pour thin fertilizer. After cutting for about 50-60 days, plant in pots, separate the roots from the matrix and plant them in the culture soil

3、 Precautions

When cutting, Prunus deltoides shoots first and then takes root, so don't transplant and loosen the soil when sprouting, otherwise it will affect the rooting
