I am having a dreadful time growing Oxalis adenophylla from bulbs. I planted my latest batch about two weeks ago, watered them and then left them alone. Because nothing was happening, I dug up a bulb from each of three pots and all were the same: no signs of fresh roots or shoots, bulbs were slightly softer then when planted, all had verdigris colored (the color of oxidized copper) "stuff" on the outside and inside when I pulled the bulbs apart. I fear that they are on their way to becoming compost. Of the 50 or so bulbs I have planted on two separate occasions, only one has managed to grow and it looks great.

Can anyone tell me what I am doing wrong?

Thanks
