Thanks, Margaret. I read your article on re-bloom Am's. It's very similar to other articles I have read except some details in re-building the bulbs. Even in your zone 3a, it seems to miss the ideal " re-bloom at Christmas" timeline the same case to most, if not all, Am's growers. I wonder if you can buy a bulb in Oct and force it bloom at (or close to) Christmas, why it's so hard to have it bloom again at next year's Christmas? Isn't the bulb you buy has been grown and re-built b4 it's on sale? If so, why can't we repeat the same process and make it re-bloom at next Christmas? Just curious. By the way, are there many growers first time got their bulbs and be able to force blooming at Christmas? Does it depend on which variety? Sorry for lot of questions.
