Bulbs can be planted in layers by digging up an entire area down to the proper depth, placing the bulbs and covering; or in individual holes dug for each bulb. 

• Determine the planting depth for the type of bulb you’re planting. If planted too deep, flowers will bloom late or not at all. If planted too shallow, new growth may become exposed too soon and risk damage by cold temperatures. 
• Prepare the soil by loosening and mixing in organic material if needed for added nutrients or to improve drainage. 
• Place the bulbs with the pointy-end up and with the roots down. If you’re not sure of the top or bottom of the bulb, plant it on its side and it will find its way to the surface.
• Cover with soil and a light layer of mulch.
• Newly planted bulbs should be watered well to get settled in.
• If needed, protect bulbs from critters by staking down wire mesh or chicken wire over the beds or planting them in bulb baskets or wire cages.
