Can Walnut Shells Be Used as Mulch?

What can I do with walnut shells in my garden?

Nut shells are extremely hard and breaking them into bits helps to speed the decomposition process. Mix the broken nut shells with dried leaves, small twigs and other brown ingredients until you have a 2-inch (5 cm.) layer. Cover it with a similar layer of green ingredients, then some garden soil and a good watering.
