Day Lillies

The yard in my new house is full of spent daylily's.  I have no idea if I am supposed to cut off the dead stalks.  Or wait until Fall.  There are two many to dig up.   I am sure they have not been divided in at least two years because no one has lived here for two years.  (I think)  The husband of this house was the gardener.  His wife did not garden.  I can feel his ghost here.  Because he was elderly and has passed on. We are having the well drilled deeper as it is going dry or has become what they call,  a low yield well. And to do that they will have to cut down the river birch at the corner of the garage.  They can't get their drilling rig in here with the tree in the way.  Makes me sad. It is a beautiful river birch.  My husband does not even seem to care.  He said, Its just a river birch.  They aren't that good a tree, are they?  Sad.  All tree's are good.  Tiny seems a bit better than he was in Florida. But he gets more itching when it gets hot. Luckily summer seems to be over up here.  We have not had to run air conditioning in days and days.  Here are my dead day lilys.
