2. Soil: Longhua prefers acidic soil, and the most suitable soil pH value is 5-5.5. The soil with good drainage and good fertilizer conservation can grow well, and the best cultivated soil is sandy loam or humus loam rich in organic matter.

4. Transplanting: the cuttings should be transplanted after rooting, and the root length should be removed from the cutting bed when the root length is less than 2cm. If the root is longer than 2cm, it is easy to break the root and affect the slow root and initial growth of the seedling. Dragon boat flowerpots are commonly used to cut 10~20cm diameter pots, according to the size of seedlings and the number of plants, pot cutting plants must be neat, flowers and colors consistent.
