Best soil for a raised bed?

I would suggest adding equal amounts of sharp coarse sand (or crushed rock, chicken grit is perfect) for good drainage, rehydrated coconut coir (or peat moss, though I prefer coir because it is neutral, unlike the peat which is acid) for water retention, and compost. Adding a few inches of compost or coir every year will benefit the bulbs, as the soil will break down no matter what you use.  Adding more rock or coir accordingly will let you control the drainage.

I know you don't want to use pots, but I suggest using the large pots used for ponds with holes drilled in them in addition to your buried mesh. The reason is that I have buried mesh in my garden raised beds (3/8" galv.) but moles have still made their way in. Maybe use a few pots for your more tasty bulbs? They make them in at least 5 gallon sizes, just make sure to drill holes in the bottoms.
