Hymenocallis maximilianii question!

Hi Dave and all,

I start my Hymenocallis seeds on a sandy or gritty potting mix, the same 
that I use for almost all my bulbs growing in containers.  Some 
Hymenocallis do need to be in water in the summer when growing, but almost 
all of them also need (or at least tolerate) a dry rest period in 
winter.  Hymenocallis like it warm and sunny.  Get them as warm as possible 
and as much sun as possible.  Don't dry the seeds and don't bake the bulbs.

I feed them with a soluble fertilizer when they are watered.  They can use 
a lot of nutrients when growing.  All bulbs need more nitrogen and 
potassium ("potash") than they need phosphorous (phosphate).  I use and 
recommend Scott's/Peters/Jack's Professional Peatlite mix (N-P-K = 
20-10-20) with more nitrate nitrogen than ammonia/urea nitrogen.  It also 
contains micronutrients and trace elements.  You might have to add 
supplemental chelated iron once during the season.

Good luck!
