Re: how deep?
I read an interesting article some time ago on this very topic. It discussed planting suckers at different depths. The suckers that were planted deeper yielded more fruit than the ones that were planted shallowly. Kind of blew my mind, as it sort of goes against what we are commonly told to do, which is to plant with the roots just below the soil surface. This season, I will be planting my corms deeper than I have done so previously. Of course, the soil should be sufficiently warm also. This study was done on a banana plantation in the tropics, so no worries there with cold soil.
