Not flowering

Question from Matt D-W

I was given a large specimen 2 years ago, it remained in a large pot because of moving, after moving early this year, I divided the specimen and planted. In all of this time I have not had one single flower. Has anyone any idea why this could be?

Zantedeschia aethiopica

Question from Brian Dryburgh

I have recently planted 3 large specimen Zantedeschia aethiopica which were doing really well until this last week. Despite watering them every night, the leaves are turning yellow and the trumpet flowers are dying. They are planted in a south facing sheltered spot in full sun. The ground is very wet and the surface is mulched with bark chips. Help! Any suggestions would be very welcome. Thanks in advance. Brian
