germination instructions Dorstenia contrajaerva - Contra Heirba:
There is no pre-treatment of the seeds required.
The seeds are sown in mineral-based cat litter (no clumping litter) or perlite (germ-free) in plastic-pots.
Please sow the seeds on the mineral soil. Bigger seeds need to be covered with the mineral soil, small seeds should remain on the surface.
Then put the plastic pot in a ziplock bag - with a pot size of 6 cm , a ziplock bag of size 12 x 17 cm is recommended .
Fill in the ziplock bag as much tap water with a few drops of universal fertilizer, so that after the absorption of the substrate a few mm of water remain on the bottom. Then close the ziplock bag - Ready!
More watering is not required because no moisture evaporates through the ziplock bag .
Location: on the windowsill or in a small greenhouse in partial shade, daytime temperatures at about 73-83 F, somewhat lower at night at 68-72 F. The resulting micro-climate provides ideal conditions for germination.
