Help! We have been away for 2.5 weeks and returned to find our Fritallaria, which had been 8 inches out of the ground looking green and happy when we left, completely dead. It is now brown and devoid of any sign of life. What happened? Is there any point in digging up the tuber to have a look, and maybe replant? We are mystified, although we hear it's been very soggy and I know these plants are prone to rot, but hadn't thought two weeks of soggy weather would be so devastating.
