You can use any organic matter - compost, shredded leaves, straw, etc. to provide protection for your bulbs, rhizomes and tubers. The purpose of the mulch is to help moderate soil temperatures against the freeze/thaw cycle that can heave the bulbs out of the soil. 3-4 inches is plenty thick enough for adequate protection in your growing region. Next spring you should be rewarded for your efforts. Enjoy your beautiful garden!
