I would recommend cutting back the growth that is more than 4 to 6 inches long. If you do not do this, those longest sprouts will begin to develop leaves and put added demand for stored nutrients and moisture from the rhizome. You can choose to leave the very short sprouts and either cut them back "slightly" before planting if necessary. Please do not plant the rhizome very deep. The planting depth should never exceed two to four inches. Do not cut close to the rhizome. You may even notice a slight swelling at the base of the sprout. Do not cut this swelling area; this is where future rhizome growth will occur.

Thanks Kent,

Just wondered if I should cover them with a blanket of some kind to prevent the daylight from teasing them into continued growth? We still have a couple of weeks before the fear of frost is gone.

I am guessing that the warm temperature has triggered the growth and the lack of sunlight contributes to the leggy growth. The use of a cover likely would be better if applied earlier and primarily to prevent water loss. If a cover is sometimes used you might need to allow for a bit of air exchange.
