I, too, have a few with red streaking... I'm not about to throw away good bulbs if I can save them... so, I have those few isolated from the rest of my collection, and I've been treating them with Schultz's 3-in-1 insecticide/miticide/fungicide. Slowly, but surely, they are beginning to put out new growth without the red streaking. I spritz the red streaked areas with the 3-in-1 spray at about 2 week intervals.

If the red is not streaking from obvious mite damage, but is more a rot issue, I remove the rotten areas, dust with Captan, and hope for the best.

So far, I've managed to save a few bulbs from certain death by taking optimal care of their problems and keeping a close eye on them. Bottom watering keeps the problems from getting worse or spreading.

I can't, in all good conscience, pitch out a bulb that still has hope of growing and recovering... and I'm glad I went through the trouble of trying to save them. I expect full recoveries and flowers next year!

I am trying something new. I have 4 bulbs growing in a tub.

One of the bulbs has red blotch, I think. I did not want to dig it up since I had just fertilized the bulbs with Bayer All in One, a systemic fertilizer, fungicide and insecticide.

The red area did not look too bad so I carefully cut it out while the bulb was still in the ground. I made a solution of 1 to 10 bleach to water and dribbled the solution over the outer part of the bulb.

I have Schultz 3 in 1, but did not want to use that since the bulb must be stressed after its "surgery. "

I have no idea whether or not this will work. Time will tell.

I took pictures, but I don't know how to embed them in a message.

When I remove rotting areas through surgery, I usually dust the area with Captan afterward. That seems to keep any fungus from returning. Most of the rotten areas on my bulbs have been at the soil line, or were apparent when I first received the bulb. I haven't been able to get away with leaving the bulb in soil, although I would if I could!

I think the Bayer systemic should help a lot! That's what I have waiting out in the garage for the day I bring my bulbs outdoors. I've used it on roses with very good results!

I'd be interested to know how the bleach solution works for you... I'm not sure what it would do to raw bulb flesh, so I haven't tried it.
