i find that hybrid tulip bulbs really do better dried in the sun for a few days, not 90 degree blazing sun on a humid day but bright sun on a nice cooler days, even left through rain, the bulbs "cure better"

Rimmer de Vries's comments touched me as bringing up a topic we've not touched on since I've been on this list, i.e., putting a bulb into the sun for days to restore it.  I've done this over and over with all manner of bulbs-- believing that some sort of response must have been enabled  in over a few million years ro allow bulbs to survive after avalanches, being uprooted from other causes, i.e., predation by really big vegetable eaters, earthquakes, rivers shifting their beds,  etc.  I've found it useful when other things fail; regard it as somewhatg prophylactic for situations where moving out of season coulld risk rot,etc.

Re the daffodils he mentions, I'd let them sit for days--even up to 10 days to assure their continued growth and recovery in the fall-winter regrowth cycle--laying down roots and beginning to set forth on a Hymenocallis caroliniana that I left in a bag out too long so that a chipmunk decided it might be worth eating. I am now cooking in the sun for 4 hrs. day for about 2 weeks.  I may lose most of this year's growth, but. I'll plant it in about a week and see

The Daffodil growers dig bulbs 6 weeks after blooming and immediately put them in mesh bags and let sit in the sun for a few hrs. then store in cool well ventilated area. It seems that if you try to replant them and water in they will rot, as narcissus do not grow new roots until the cool soil of the fall.

I suspect you are growing miniature narcissus , i dug my miniature narcissus when the foliage was yellow to gone and re planted them in barely damp mix in my frame under glass or a sheet of plywood with ventilation under it. , but i do not think you need to wait that long, just let them dry out a little- few hours in well ventilated area

I know there are some daffodil enthusiasts in this list, Bill Lee? please chime in

I agree with Arnold's intuition and Lauw's professional opinion that any bulb should be put back into soil as soon as it's feasible. When I was selling surplus bulbs from my collection, I kept those without permanent roots in paper bags for a few weeks, but I kept them in a cool, dim room (my dining room -- no dinner parties in August!). Those without tunics and those with permanent roots I put in very slightly moistened vermiculite in plastic sandwich bags inside the paper bags, and also shipped them in vermiculite.

I have a related question now that I hope one of our professional growers can answer. I need to lift a lot of narcissus and colchicum bulbs to move them to my new garden. Our region has just experienced the wettest late spring ever recorded, and the soil is much damper than it would normally be at this time of year. My instinct tells me that I should leave these bulbs undisturbed until the soil dries out, even if their foliage has withered. Is this right, or can I lift and replant them even if there is still some moisture in the soil? The soil here is well drained gritty loam, but not sand. And should I spread out the colchicum corms in a dry place after I lift them, or can I just put them in paper bags for 4 to 6 weeks?

I'm also lifting some erythroniums and trilliums soon, but I'm going to pot them up immediately. My potted bulbs in the frames (which are presently being dismantled, no doubt to the detriment of some of the bulbs that got more rain than they would want) should be able to stay in their pots until the deep beds in the new bulb house are ready to receive them in August.

At least the awful weather (it was also very cold) seems to have delayed the emergence of the bulb fly so long that the narcissus foliage that would usually attract it is completely withered and removed. I had also protected the sternbergias and galanthus with Reemay (under glass) and with a topdressing of gravel or bark, respectively (in the open).
