1、 Cutting propagation
1. Time: cutting is the main propagation method of longevity flower. It is generally carried out from March to may in spring or from August to September when summer and autumn intersect. In other times, the survival will be affected by plant dormancy, but it is not a big problem in greenhouse p>
2. Seedling selection: select healthy and vigorous plants and cut 5 cm long mature fleshy stems from them without removing leaves p>
3. Soil selection: the selection of matrix is also particularly important. It is generally mixed with perlite, vermiculite and peat, which has good drainage and air permeability p>
4. Planting: plant cuttings on the substrate and cover them with plastic film after watering, which can have a good thermal insulation effect p>
5. Transplanting: take root two to three weeks after planting, keep the substrate moist, and put it in the semi shade to receive sunlight scattering. After one month, it can be transplanted into the pot p>
2、 Sowing and propagation
1. Time: the sowing method is generally carried out in spring or autumn. The appropriate time is March. Due to the gradual rise of temperature, it is good for the development of seeds p>
2. Seed selection: longevity flower has only one petal flower with seeds, and there are many seeds. Generally, multiple seeds can be sown together, which can improve the survival rate p>
3. Soil selection: sowing requires a high substrate. It is mixed with rotten leaf soil, garden soil and humus soil, and disinfected after ripening as the substrate p>
4. Seeding: Sprinkle the seeds evenly on the substrate and cover the surface with fine soil, not too thick soil p>
5. Curing: cover the surface with film and store it in a warm and ventilated place. The basin soil needs to be kept wet and controlled at about 20 ℃ p>
6. Transplanting: buds can be produced in about two weeks. At this time, they can be exposed to astigmatism. At the same time, after the leaves appear, they should be watered with a little fertilizer. They can be transplanted in summer p>
