B. grandis tubers
Generally the tubers break dormancy in January, but to my surprise most have started already. I hope growth will be slow as I am still growing indoors and will do so for a couple of months or more. I have a recipe for slowing growth of little bulbs which are often forced for house blooming (paperwhites and the like) and I rather hope I don't need to try it, I never have. If anyone wants to know what the recipe is (I found it in a garden magazine) I will post it.
