Pine shavings, alfalfa hay, cypress bedding to mulch blueberry plants?

I bought 2 young blueberry plants from Home Depot in March and have been having hard time finding pine bark or needles to mulch my plants. Is it okay to use pine shavings, alfalfa hay, or cypress bedding instead? Here are the products that I've found.

Cypress bedding:

The only bit of info I have to offer is that cypress takes a LOOOONG time to decompose.  The wood is excellent for outdoor building due to that (I read that the most sought after cypress are logs that have stayed in the water for 25 - 100 years).  

Because it's commonly used as mulch in our neck of the woods, I've seen far too many gardens ruined because the cypress chips have been applied year after year after year, and since they don't decompose, the chips sink and displace the soil that would otherwise feed the plants.   It may be something to keep in mind while you are making your decision.

I wouldn't bother mulching, myself.  Small plants and "weeds" themselves make a better mulch unless it's actually underneath a tree.  Usually people mulch from laziness, or because they've heard it prevents water loss, but anything but a light and fluffy mulch also creates a 'wicking action', bringing water to the surface so it can evaporate. Mulchless places appear to be drier, but it's just because the top inch of soil dries out.  Mosses, wood sorrel, sedums, plantain, anything that shades the soil, but it depends on your location.

Also, if you're trying to lower PH at the advice of an underpaid home depot garden salesperson, keep in mind what I wrote at the link below (last post).  Just use compost.
