Hi Michael,

Well, I figured that he might need to amend the soil some, but
don't most plants in the desert grow in winter? I don't really
know what AZ's climate is like but I assumed that the bulbs would
stay dormant through the summer and grow in the winter, just like
they are doing anyway. How much does it rain there in the wet
season? Is AZ a drier desert than where bulbous Drosera grow? In
The Private Lives of Plants, they showed a bit a the area they grow
in and it was very dry until the rain and then Sundews popped up!

Sorry your plants suffered so, but since the ones I'm thinking should
grow in the winter how does that effect water needs?
