If you do put them in pots, be sure to keep them in the coolest, shadiest part of the garden so they'll go slowly and maybe have a chance to develop some roots, too. A pot will tend to warm up faster than the ground, especially if it's in the sun for any part of the day. I'd water with cold !! water, too. Again, keep them going slowly if you can. Even if they just make leaves and roots they will still re-generate a bulb for next year, which is the best-case scenario, I think.
