Axen börjar nu mörkna rejält och hårdna.
Kan jag så direkt eller skall frön av bambu förberedas (kylas, upphettas, vattnas, etc) ?
Tacksam för svar

Hej.
Spännande med dina bambufrön.
Jag blev väldigt nyfiken och sökte en del på nätet.
Här är ett stycke text om bambufrön.
Behöver du hjälp med översättning så hör av dig.
Får du många frön så skulle jag bli glad om du kunde avvara några till mig.

Some bamboo seed, such as Phyllostachys need to be fully ripened before harvest. This is especially true if the seeds are not to be planted immediately. Seeds of some bamboos are viable and may be planted while still green. Sasa, Indocalamus, and Pleioblastus are in this group. The seeds of Melocanna baccifera, a very large seed type germinate while still on the bamboo.

When seeds are very easily removed from the inflorescence they are most likely ripe. Even with these bamboos, it is probably a good idea to let them dry and thoroughly ripen if they aren't to be planted promptly. Leaving seed on the plant can be chancy though, as birds, bugs and rodents may harvest the seeds. If possible you may want to protect the plant. The seeds even may fall as the result of wind or just bumping the plant.

Seeds may be harvested individually by hand on a small plant. Or, sometimes seeds are found on the ground under the plant. If possible you can place a tarpaulin beside or under the plant and shake the flowering culms over the tarp. If you are sure the seeds are ripe, you can cut the culms to make it easier to shake them on the tarp. After collecting the seed and probably much chaff and debris, you can use the wind or a fan to blow away much of this waste.

I place the seed directly in small pots which I then water and place in plastic bags until they have germinated and the seedlings had grown a few inches. Care should be taken so as not to have the soil too wet. This has sometimes been a problem for us. If I have only a few seed I sometimes put them between moist paper towels which are placed in plastic bags in a warm place until germination. This can take anywhere from just a few days to over a year. Each bamboo has a different schedule. Then, I put them in the small pots which I also put in plastic bags. A good soil-less mix, good watering techniques, and bright (not direct sun) light, are important to grow bamboo from seed.

Two of our recent projects are the recovery of Phyllostachys flexuosa and the attempt of the recovery of Phyllostachys aurea albovariegata. As you may surmise by the preceding statement, one project is working and the other is still in question. We have had success with the Phyllostachys flexuosa recovery
