Hi Willowstar,
My Salsola are germinating more ( I have now around 10 of them ). Did you germinate yours in pots ? I did, and I actually overwater them too ( perhaps that is the reason it germinate )...
.
I am not sure if that is the correct way ( over watering ) as the seed package give no instructions( it was from evergreen seed company ) , but perhaps you could try couple in this way. I notice that most germinated ones are those from bigger seeds.
I will not be giving any more water until they need it. Will keep you posted and hope you could germinate yours too.
Good luck,
Momol
