The daidai flower can be produced by three propagation methods: seed, cutting and grafting, but the seedlings produced by the seeds are easy to mutate, so they are rarely used in production, or as rootstocks. Cutting propagation in April-May selected well-growing, disease-free mother plant robust branches as cuttings, it will be cut into 15-20 cm long. Remove the lower leaves of the cuttings and insert them obliquely on the sand bed to keep the seedling bed moist. At a suitable temperature, it can take root in January. Grafting propagation is often used in production, and the method of branch grafting or relying on grafting can be used. It can be transplanted after 1-2 years of survival.

3. Field management

Daidai flower has the characteristics of multiple shoots, which needs to consume a lot of nutrients, so it is necessary to topdressing for many times, mainly organic fertilizer and some quick-acting fertilizer properly.
