Can I grow my own Ephedra?
Ephedra normally grows in subtropical conditions making it very hard to grow some yourself. Also, a lot of plants are needed to get the amount you need for a good dosage. Still, there are grow kits available for those who would like to try.

Cultivation and Propagation: Ephedra should be planted in dry locations. It thrives in ordinary loamy soil and does very well in a loose rocky soil with full sun and little water. It is most often propagated by division of the clumps in spring, and seeds sown in a light sandy soil in early spring. It may also be propagated by layers and suckers. It makes an excellent ground cover on rocky slopes.

Harvesting: The tops of the branches may be picked and dried at any time as long as the plant is not denuded or the branches cut back past the viable buds.

Svjv er ephedra ganske lovligt i Danmark, så der er nok ikke specielt god økonomi i et gro det selv. Ret mig endelig.

Jeg vil foreslå dig at købe nogle frø, for derefter at smide dem i noget muldjord og vande dem... Det er som regelt sådan man sår botaniske vækster.

Min egen erfaring med Ephedra Nevadensis, er at den faktisk ikke behøver særligt meget pleje.

Som jeg har quotet står der at man bør så dem i let sandet jord i det tidlige forår (hvornår det så end kommer)...

Mht. høsttidspunkter - you're on your own!
