How deep in the ground do basjoo corms go?
 

I planted 8" tall basjoo's last spring - 10 of them. By fall they were 3 feet tall and i chopped their stems down to 6" and mulched. The stems were 2-4 inches thick by then. With the warm weather I began looking at how they fared and they were mush right down to the ground. So I started chopping lower and lower until I found alive tissue.

Here is how they all looked at ground level:



Still mushy, so I went deeper with the knife. At about 1/2" to 1" below the soil line I found viable tissue in about half and it looked like this:





A few of them, the stem seemed to disappear to this little knub or nothing at all like this:



I'm wondering if I hacked all the way to the bottom of the corm and those are toast? I thought the corms went at least a few inches into the soil.

It depends on the age and the variety, but they can go about as deep as 2ft or so (some probably go deeper), most probably within 1ft-18in. A small plant like yours though would be mostly within the first foot of soil.
