Just adding my methods again, in my Massachusetts greenhouse I grow my Nerine sarniensis in 6 inch square plasting pots, using ProMix BX mixed with 1/3 Espoma Soil Perfector ( a fired clay pellet). This is my tenth year growing one N. sarniensis crosses, and I agree with Nick, plastic pots seem to keep the bulbs plumper and the roots more stable than in clay, I too have tried both. As for transplanting, or dividing, I am curious about other growers and what you may be doing. I've been lazy over the past few years, and have not divided some pots, and they are are starting to bulge with firm bulbs. I am noticing that some pots have three flower buds, something that I have not seen in my collection in the past. Also, I am getting nearly a 90% bloom rate now that I have my bulbs in larger pots, with a little summer moisture. Last year I picked all of my flowers and photographed them so that I could document each variety. I then had some fun arranging them by color order ( see here, on my blog) http://growingwithplants.com/2010/10/… I wonder if I am getting more bloom this year, because I picked all of the blossoms last year?
