Since you have a soil that doesn't drain well and a planting hole will fill like it was a bowl holding water. What you need to do is dig a slight hole about 1/2 as depth as the length of the corm. Backfill it with top soil and set the corm on top speading out the roots. Then mound good, well drain soil around the corm for about 2ft -3 ft or more around the corm. ... This makes a small raise bed so water can drain out and run-off at the top of the ground. The roots will eventually grow down and loosen the clayish soil. ... You might check to see if the clay layer is thin and has a sand layer under it.
