So an easy and safe answer is to build a slightly raised bed. Take a close look at how HMelendez
did his bed for each nana plant. The tops of these corms appear to be about 6 to 10" above the ground. An Update Of My Latest Nana Plants 2018!
Well I pulled out a small palm about a week ago and the hole was 24" x6" deep,filled with water that day and the next.
Then 5 days later I filled it again and yesterday it was just a muddy bottom,tried digging it 12"x12" for the test and needed to move that deeper hole over about 12".
I'll look at the raised bed thread,this is already raised but can go a few more inches,and a deeper pilot hole under the plant can also be dug and filled with a good draining media as well as a framed upper form so the corm is always above ground level for safety.
My only issue is the far reaching roots which if too dense could succumb to rot.
These beds also have good 3 or 4" drains which work well for heavy rains.
