Multiplication

The Pawlownia it can be multiplied by sowing its seeds directly in a pot during spring. You can also try planting semi-woody cuttings in pots with sandy substrates in that season.

The kiri tree is a plant that gives very good shade, but it also has several very interesting curiosities. It is a vegetable that can survive fire easily, since its roots can regenerate, and as it also has a very fast growth in a short time it can become the plant it was before the fire.

The leaves are rich in nitrogen, one of the essential macronutrients for the proper growth of plants, so that when the time comes they can be used as natural fertilizer. What's more, gives very good shade, so it can be used as a shade tree under which to protect itself during the hottest days of the year.

Its roots prevent soil erosion, something that is especially interesting in areas where this is a major problem. And not only that, but they are well adapted to living on poor land.

Can you help us stop climate change?

    hello good afternoon, night or day a great greeting what a good blog a question regarding this tree how feasible it is to make bonsai

      Hello Jesus.
      Good afternoon from Spain 🙂
      Pawlonia has leaves too large to be worked as bonsai. Even so, with fertilizers poor in nitrogen and pruning, its size can be reduced a little ..., but they would still remain large.
      To make bonsai it is best to use small-leaved trees, such as elms or zelkovas.
      A greeting.

    The Pawlonia is a forest tree that has "misleading advertising" as the saving tree of the world, etc etc ... and is yet another of the inventions of some Chinese or Spanish laboratory. There are pages of "kiri" or pawlonia that really suck, because they are sterile clones with a commercial patent, that is, you give space to a transnational to do its business (PRODUCTIVE COLONIALISM), disguised as "ecological". Chinese hybrids are not sterile and therefore can be dispersed in forests ... with the damage that this implies. don't be fooled by the media. Plant native to the area in which it lives, they are the best adapted to its climate, the introduced species only take care of draining resources, such as water.

      Hello Roberto.
      Right, that's what I think. Too much publicity is being given to a tree that it really is not as "all-rounder" as they say. In addition, it needs a lot of water to be able to feed the leaves, so it should never be planted in climates where rainfall is rather scarce.
      A greeting.
