no, it won't return to the top once mixed in - cedar is one of the longer lasting woods, needs lots of N to break down, but it will - meanwhile you'll need to be adding regular hi-N materials to supply enuff for the plants, as the cedar will tie it up

What qualifies as a high-N material? I'll be adding some tomorrow because this is worrying me! Thanks so much for your reply!

P.S. Approximately how long do you think it will take for the buried ones to break down?

That is one of the reasons why I do not recommend using wood chips, or any other woody material, as a mulch in flower beds. If your soil has been well amended with compost and other organic matter there should be enough Nitrogen in the soil to take care of a small amount of woody material, the problem really comes when large quantities of woody material are mixed into the soil. Watch the daylilly and see how it grows before getting overly concerned. Depending on how healthy your soil is the cedar mulch may get digested fairly fast, a year, or it may last for quite some time if the soil is not really healthy.

"there's no room for just the soil to be stacked without the mulch envading, etc! I just planted a new Daylily plant that I got today and it was such a mess, with the mulch getting all throughout the soil!"

daylily, you might find this will help, what I do when planting is push the mulch aside so it is out of the way of the hole Im digging, then as I dig out the soil, I put it into a pot, put the plant in, and then use the soil from the pot to fill it in, push the mulch back over to cover it all up. if there isnt enough room to push the mulch aside, just have a second pot on hand to put the mulch into aswell and tip it back on when youre finished planting.

I mulch almost excusively with pine straw.
