Can you put them in a pot temporarily? You could put multiples in, they won't grow enough roots that you couldn't easily separate them.

I'd leave the planting depth the same.

I always just kept them in the basement (when I lived in OH) until it was warm enough to put them in the ground.

Thanks for your suggestions. Pots were not an option because I just don't have room for them. My living room window area is already filled. Purpleinopp, that's what I usually do but I wanted to get a head start so I can enjoy the blooms. In my area, the blooms usually start in September and are hit by frost. Anyway, we had a warm, wet day today and I went out and put them all in - 22 corms including some I overwintered from the last 2 years. I was amazed at how well they all grew. But the weather is crazy this year, lows of 5 degrees expected in a few days. So I don't know what Mother Nature has in store. I hope they survive.

Great job on keeping them (and multiplying them) so far!

Oh that sounds frustrating, quite a bit of difference between where I was in 5b central OH and where you are - much earlier frost. FWIW, down here they are about finished already - those established in previous years. I did add some new ones that are just coming up with foliage, but I don't expect those to bloom this year. Ya' never know though...

I know the crowded indoor/winter conditions all too well! It's tough deciding what to save when space is at a premium. At least in OH I had a basement for cold/dormant storage. Here, it's either inside or outside.

If you get an inside line on what Mother Nature has in store, you'll make millions!!

Sending good vibes to your bulbs!
