Well... you won't know unless you try... my thought would be to carefully prop the basal plate and roots in a medium, after soaking the roots in Superthrive. Water the medium carefully and lightly... and give it some bottom heat. A little rooting hormone powder on the roots might spur some growth, too.

Give it a shot... what have you got to lose? I would try, I know that! Keep us informed. Good luck!

Anyone else have further thoughts?

I have to agree with Jodi, if you try, you might succeed. If you throw it away, you definitely won't have any chance of success.

I think there is a pretty good chance it will grow--do as recommended above. But most of the roots look like they are dead. If they are dry, I would pull them off before planting. If dry and dead they will not puff up and wouldn't be a good measure of life in the bulb. The cut areas look like they are closing up nicely. Go for it.

I guess you are right. What's there to lose except a bit of soil?

Do you recommend that I use vermiculite as the medium or would that retain too much moisture?

I will wait until Tuesday so that I can take it to my office on Wednesday. It is too cold for a sick bulb in my house.

I can also swab the basal plate and the wounded area with Captan before I pot it up. I hope that using Captan after using sulfur (although I did try to rinse the sulfur off) won't hurt it.

I would not use straight vermiculite... it might retain too much moisture... I'm not sure. I would most likely use a porous well-draining medium, and I would take very special care when watering. Be careful not to over pot it, either... it will have a difficult time filling up a large pot with roots right now. I would put it in the smallest pot that it will comfortably fit in. I would also make sure to keep it out of direct sun for a little while, so it can concentrate on growing roots and healing. Bright indirect light would be good. Bottom heat would be marvelous, if at all possible.

So, bright and warm, careful watering, very well-draining medium... and I think using Captan will be fine. I would use it dry, dabbing it on the wound surface with a paintbrush. It wouldn't hurt to dab it all the way around the bulb where it meets the basal plate... this will help prevent any problems in that area. The bulb is super stressed out right now, and has a very low immune system... any help you can give it will be beneficial.

I wish you luck... and if you need further help, we're all right here, ready to answer any questions!
