Hi all , In few days I will receive bulbs of Phaedranassa and Weldenia - could please anyone give me any suggestions what kind of potting mix they like . It is enough when I know in which relation mineralic and organic are ( 1:1 ) or ( 2:1 ) or ( 1:2 ) or similar . I had look under Google - but there is nothing special . Thank you in advance. Best wishes Hans
