Everyone, Thank you for all the fascinating and informative feedback. There's a lot to absorb (excuse the pun). I think assessing the roots of bulbs in dormancy will do a lot to inform me whether or not to water. Last year my little yearling bulbs (lifted by me, I know, not great) spent a long dry summer in envelopes, and when planted this year, grew well and some even flowered. As this success involved no summer watering, I think I'll follow the same path again. As mentioned, I've really enjoyed reading the thread. Lots of valuable info. Thanks a lot. David.
