I live in NYC sand have a have an existing garden bed that I have put perennial bulbs in a few years ago. I was going to raise the soil of the garden bed so the level is almost to the top of the bed (about 6-8"). I have some peonies and a hydrangea tree as well. If I do this, will the bulbs come up in the spring again? How about the hydrangea and peonies? I am afraid the extra soil might be too much soil for them to resurface in spring... would love to know anyone's thoughts on trying to find these bulbs (hyacinth, allium, daffodils, crocus) or just replant new ones? What about the peonies? - should I stay least dig those up?

I would raise the bulbs and the plants up to the proper depth.

Certainly raise your peony, they don't like to be planted more then an inch or so below the surface. If they are planted to deep you might get foliage but they won't flower. Some bulbs such as lilies will find their own comfort level. I can't remember what the mechanism is called but they can pull themselves up or down over time to keep healthy. Some bulbs if planted to deep will eventually bloom but maybe later then normal. I have no idea which bulbs would do this and which wouldn't, it would be a risk you would have to judge for yourself. As I have aged and my stamina has suffered I have gotten a bit tough on making some plants fend for themselves. Unless they are very fussy about the soil level (peony) or very expensive or for some reason have special meaning to me I tend to take the risk of loosing plants in stride by taking a few more shortcuts. In general though I would be cautious about not raising the plants but with sandy soil they may not struggle with deeper then normal levels as they do with other soil types. Blinking

Bulbs, maybe OK, I would leave them.
Peonies, MUST raise them as stated. the keep flowering. The roots need cold in order to bloom; too much soil or mulch on top hinders that.
