I have a 2-yr-old hallertauer plant in a ~20gal planter that didn't do much for the second year in a row this past season. I was going to transfer it to the garden because I'm convinced the soil in the planter just isn't rich enough to support the plant. I decided to drag the planter inside this winter though instead of putting it in the garden before the freeze.
It's been months since the bines withered away and the plant had clearly readied itself for winter, but despite the lack of sunlight where the planter is, new bines started coming up a couple weeks ago. Should I let the bugger keep going to get a start on the spring growth? Or will growth over the winter be detrimental to its flowering cycle?
