The ripe seeds germinate where they reach the ground without any problems, even in small cracks in walls and pavements. They can grow into two meter high young plants within a year. It is not for nothing that the bluebell tree is considered to grow very quickly. However, many of these young trees freeze to death in the first winter.

What do I do if my bluebell tree doesn't bloom?

If your bluebell tree has never bloomed then it may just be too young for it. As a rule, the first bloom does not appear until a tree is around three to five years old.

If your paulownia is older, the climate might not please him. The bluebell tree is hardy, but the tender buds are not. They freeze to death quite often in a rough area. Only winter protection made of foil or fleece can help here.

How do I treat purchased seeds?

In principle, you can sow the bluebell tree all year round, but February is recommended. Then the young plants are well rooted and strong by autumn. Sprinkle the seeds thinly on the growing substrate, (9.05 € at Amazon *) peat or a mixture of soil and sand. Keep this evenly moist in a light, warm place.

Targeted cultivation step by step:

  • Collect and dry seeds in autumn, buy alternative
  • Sowing possible all year round, ideally in February
  • Growing vessel: wide and flat (bowl)
  • Substrate: sand-earth mixture or peat
  • Sow thinly, seeds are very small
  • Keep the substrate evenly moist
  • Location: warm and bright
  • If necessary cover the cultivation vessel with foil (increases or maintains the humidity)
