How about planting your more invasive bulbs in plastic aquatic plant containers. They come in various shapes and sizes, I have tried it and it works, the only slight problem is irrigation as these containers can dry reasonably rapidly, so beware Mary Sue, I use plastic baskets (the same size of pots) which are sunk into the raised beds. However, now the nursery is invaded by mice (mole, voles) I wrap up these baskets in wire netting, or plant the bulbs in wire cages 100cm by 10 wide 15cm high. Bulbs are well protected, grown well and are easily to be recovered if necessary. Only stolon forming species partly escape, but it is a minorproblem.
