The sowing
In autumn, small fruits form on the seed heads of the mammoth leaf, in which the sensitive seeds ripen. If the pulp is removed, they should be sown immediately. Covered thinly with substrate and kept evenly moist, the seeds should germinate after a few days.

The optimal germination temperature is between 15 ° C and 20 ° C. Make sure that the humidity is constant. The best way to achieve this is to cover the cultivation vessel with glass or transparent foil. Daily ventilation prevents the formation of mold. Older, already dry seeds germinate poorly or not at all.
Where do I get the seeds from?
If you don't have a mammoth leaf yet and therefore don't have your own seeds, you may ask garden friends or the neighborhood. You should also sow these freshly. Alternatively, you can also find seeds in online shops.
Split the mammoth leaf
Much more promising than that sowing is the division. This should be done in spring when the first leaf attachments are visible. Separate a shoot with a clearly visible leaf attachment, possibly several in the case of a very large plant. Do not dig up the old plant completely; it is better to only expose part of the root ball.
It is best to pull the offshoots in a pot which you fill with pond soil or moist garden soil. Like the mother plant, the young plants become grow quite quickly. They can be planted out after three to four weeks. In a rough area, however, is recommended frost-free overwintering.
The essentials in brief:
- Sowing possible, but not always successful
- only use fresh seeds
- Division can be carried out relatively easily
- ideal time for sharing: at the beginning of budding in spring
- Separate shoots with leaf roots
- It is advisable to pull the shoots forward in the pot
- possibly not until next spring plant out
Tips
Propagation by division is much more promising and easier than sowing.
