Red Daylilies & Over watering Kills

I have not been out in the garden much since last week.  I took these pictures of blooming phlox and daylilies a few days ago.

I have this phlox planted in a number of different areas. It's the one I used for the ice cream sundae bouquet.

Speaking of that little bouquet, I changed it yesterday after I accidentally broke off one of my 'Hot Papaya' coneflowers.  I didn't want to waste the flower, so I picked off all the petals and just used the top to put a big cherry on my bouquet!

Works perfect for a cherry, don't you think?

I  have a lot of these red daylilies.  I like them since they bloom in an in-between stage of gardening--right after the first big flush of Asiatic lilies is over

I have not been deadheading my daylilies this year.  It's a big chore, so I said to heck with it. 
Next year I think I will go back to deadheading each day after work.  I can't stand how messy daylilies look without deadheading. I need to either deadhead them or don't plant them. I am not doing them justice by allowing them to look like this.

Not pretty at all.

Remember the gorgeous green coneflower and red rudebeckia I bought a few weeks ago from Home Depot?  If you forgot, the following pics won't help you remember because they are only the decayed corpses of their original bodies.

 Overnight they both drooped and within two days looked like this.  I thought it was impossible to overwater during 90 -95 degree days.   Just for kicks, I pulled the plants out and was quite angry to see this tiny root system just three inches from the top of the container:

 Had I known there was no root system, I would have never bought these plants. This is the first year I have had a problem like this.  I guess I need to take the advice I have read on the net and BEWARE OF HOME DEPOT PLANTS!
