1. Seeding method

Paulownia has its own seeds. Its seeds are in its pulp, and the fruit matures from October to November. The color of mature fruit is different from that when it is not mature. The former is yellow and the latter is cyan. We also need a certain method to collect seeds. This method is also quite simple. We just need to sun the fruits we collect and knock out the seeds after the peel cracks

After that, we need some treatment methods, so we need plant ash. We put it together with wet water, and then scrub the seeds, and then we can get pure seeds. Of course, seeds need to be stored in a certain way and can not be officially sown until March

Generally speaking, the germination rate of sown seeds is not low, but it is not very high, only about 50%. Because the seedling grows very slowly, it can be officially moved to the pot for planting only after it has grown for two years. After that, we also need to wait until the third or fourth year to plant it in the nursery. When transplanting, we must remember to bring soil mass to the root

2. Cutting method

The cutting time is in spring. It is more convenient at this time. When we grow new leaves, we get out the needed buds for cutting. However, there are also requirements for buds. Its year should be one to two years old, and its length should be about 15 cm

We have to cut it well, and then we have to insert it into the wet sand bed. When cutting, we should control the light intensity well. The light does not need to be too strong. Astigmatism is OK. In addition, we should remember to keep the humidity well

Generally speaking, it takes about 20 days to root, and it takes two or three years to transplant it into the nursery. At ordinary times, we need to water, also remember to fertilize, and in addition, remember to prune
