I just received a nice plant of Hippeastrum reticulatum var. striatifolium The wiki says it is native to Brazil and can be found in sandy soils, rich in organic matter. http://pacificbulbsociety.org/pbswiki/index.php/… would this imply an acid to neutral sandy soil for pot culture? in preparing a mix for pot culture should i use a sandy leaf mold made from neutral silica sand like i use in gardens for saricineas (pitcher plants etc) or just the local builders sand which is full of limestone. or just use any well drained mix? Thank you Rimmer SE Michigan Zone 5 please ignore the prior message which went out unedited
