I keep my apartment warm, specifically because I have plants. I've also invested in a small heat pad for plants, which helps me with certain things, like inducing root growth, seed germination, and the like.

Roots are certainly not your problem, there! I would hesitate a guess and say that you have some sort of fungal thing going on due to a combination of cold and wet... bad combo for bulb flesh!

Without a warmer, and drier, environment to keep the bulb in... I'm not sure what to tell you.

If that were my bulb, I would bring it indoors, rinse the rest of the soil from the root ball with tepid water, and tease the roots apart a bit.

I would then try to carefully remove the red areas with a very sharp, and clean, knife. I would then dust the bulb with Captan, or another anti-fungal powder, and allow it to dry for a day or two in a warm area.

Then... I would re-pot it, leaving the majority of the bulb above soil level. I would use the proper sized pot in unglazed clay, and I would use a fresh medium. My preference is for a gritty, free-draining, inorganic, bonsai-type of medium. I would water carefully, and allow the bulb to remain in a warm, sunny place to heal.

At that point, if it wanted to grow, I'd let it grow... and if continued to rest, let it be. In other words, I'd let Mother Nature take her own course of action, and basically just let the poor thing heal and gain strength.

I'm not certain, but I'm thinking that with a cold environment, you're not going to help the bulb much.

My apartment is kept at 70-74 degrees F, and in the north alcove there's a space heater that keeps that end of the leaky farmhouse apartment warm.

I wish you luck, and I hope maybe someone else can tell you more...

So many things make red spots on these bulbs. It looks like a healthy bulb to me. I've seen the pics of fungus, mites, etc. and they look a lot like the red that bulbs get that is harmless.
Seems to me about anything can cause a little of the redness and if the plant is healthy, and that bulb sure looks good and healthy to me, I'd put some soil on it and water it when ready for it to grow or leave it as it is for a while and just watch it. It looks like it could sit around like that for a while and it would do it no harm. Or spray a little fungicide on it if you like to treat things.

Here is what I decided to do with Candy Floss.

I decided to remove all the soil so that I could get a good look at what was underneath.

Here is what I saw:

It looked like there were areas that might cause problems, especially the areas between the bulb and its offsets.

I separated the bulblets from the parent. There was not enough left of the smallest offset to even try and save.

I removed much of the skin that had red or otherwise looked off color. The necks of the parent bulb and the offsets all looked like some rot was future down, so I cut the necks until they looked clean. I also removed many of the roots that had red.

AFter that, I decided to go for the modified hot water treatment. After all, Nymph survived it.

I soaked the parent and offspring in hot water. The water, at one point was 126 F. I was aiming for 120 F. I let it cool naturally so it wasn't that hot for very long. After about 1/2 hour I added bleach. 1 C bleach to 12 C water. I let the bulbs soak for 1 hour.

Then I rinsed them and put them out to dry.

Here are pictures of the treated bulb:

Here are the bulblets:

As you can see, the smaller bulblet is almost rootless. The one root that it has is not free of red.

My plan is to let the bulbs dry for about a week. Then I will pot them. The two bulbets will have clay pots, the parent will have a plastic pot with a water wick.

Since my house is cold, 63 F, I will take them to my office where it is warmer. The reason that the parent bulb will not get a clay pot is because a clay pot filled with soil is too heavy for me to carry on my walk to work.

With luck, eventually, I will see new growth. It took Nymph 10 weeks to show new growth after its surgery last year so I am prepared to wait.

Another thought I have... make sure the pots you're putting them in are not too big for the size of the bulbs. There should only be about 2 inches between the side of the bulb and the side of the pot once you center the bulb within the pot.

And don't forget to dust them again with an anti-fungal powder to help repel future problems.

I'm very serious when I say... please do a little research into the various mediums available. You'll be glad you did! I can tell you that since completely eliminating bagged soil from my growing program, and using a very gritty, larger-particled, inorganic bonsai medium, I haven't had ONE bit of rot problems. Not one!

I do have a preventative program, though... all incoming bulbs are checked, cleaned and dusted with Captan before potting. I know this helps. I'm also very careful about watering and checking for needed watering. If I'm not sure, I wait.

I hope this helps somewhat... it took me a while to get it all figured out to my satisfaction... but I'm glad I messed around with soils and wasn't satisfied with just any mix. I've really avoided a lot of headaches, I can tell you!

Good luck! They look ok now... they just need some time to dry, some anti-fungal, and some warmth and sun.

so it's okay to put bleach on bulbs? I know it's diluted, but I would think bleach AND hot water would be too intense! Thanks for sharing this post

I'll let you know in a few months.

I've never done a hot water treatment, nor have I ever used bleach... I'm very interested to see the final results. I'd like to know how they respond, and how well they grow after their treatments.

I hope they do well. :-)
