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.
