I took my two amaryllis outside for the summer, kept them watered and fertilized, and have been waiting and waiting for the foliage to yellow, dry up and fall off, a la tulips/daffodils. But no -- not only did the leaves stay on (though they got a little ragged), there are now new leaves coming up from the bulbs, and side shoots! These guys don't appear to be resting at all, and I'm afraid the new growth is going to suck out the flower energy.
What's the next step? I'm in Minnesota. Frost could come any time after mid-September, though for the last couple of years it has held off until October; and our present daytime highs are hitting 80. Next week night lows could get into the 40's. Will this tell the amaryllis to cool it? Should I leave them outside until temps get into the upper 30's?
Normal behavior, I can deal with. It's this oddball stuff I don't get -
Oh, and one more thing. The bulbs are a lot bigger than they used to be, and there are white roots crawling out of every hole in the pots. It seems like a lousy time to re-pot, with new growth coming. But once I get them to go to sleep (if ever), or at least slow down, should I try to preserve the whole root ball when I move them?
