Hello friends of bulbs and other plants, I have a HIERONYMIELLA AUREA very small baby bulb.And a amarygia parkeri 'alba' should the bulb be planted with their neck just above soil level like the amaryllis? do they have benefit if there is been added a great deal of well rotted organic material? all aid and information are most welcome. Thank You in advance,of a beginner. Regards, Marie-Paule Belgium
