rotten bulbs---sniff

Posted by shiver z4a MN (My Page) on

I've been searching this forum for how to deal with rotten bulbs, but I think I need more specific info than I've found so far. Two of my bulbs were quite mushy, so I've had to do a lot of slicing and dicing with the knife. Both bulbs had about half of their tissue removed in total. One of them had to have a small section right over the root area removed. I have heard that if the rot is directly over the roots there is no saving it----is that correct? Right now the bulbs are drying on my counter and I'm not sure what to do with them next: do I just wait a few days, then pot them up and water, or should I do something else? :(

Thanks for any suggestions...

RE: rotten bulbs---sniff

I feel your pain.

In order for the original bulb itself to survive, the central core of the bulb must survive. If the basal plate rots out underneath it, your bulb is lost, but you could possibly "sliver" or section what remains of the outer edge.

If the whole basal plate rots, your bulb is lost. But: if you can save a small section of it and the scales (bulb portion above it) you could perhaps get it to form a new bulb or bulbs (bulblets). It requires warmth, so at this time of year, a little bottom heat may be called for.

You will of course, only have a very small bulb should your efforts be successful and will have years to wait to see its first flowers, but I have done the same to save what I could of a bulb, and someday I will have nine full-sized 'Pasadena' for the price of one.

I would allow the bulb to dry for at least two weeks to allow it to callous over a bit and to see that the rotting has ceased. I would treat with a fungicide or at least dust with sulfur before attempting to propagate it.

Good luck!

Robert.

I lost three of my bulbs that got frozen and now are rotten. Fortunately, Jaguar had a bulblet next to it that didn't freeze, so I have that bublet healthy. I hope, it will survive. I rebought the other two varieties.

Hello Shiver. I agree with Raydio's advice. I had this pics in file for a while and just didn't have enough time to post them. Hope it helps. What to do with a rotten bulb...
THE ROTTEN BULB: no roots.. some parts of the basal plate was soft, reddish and squishy. I tried to scrape all of those rotten parts and this was how it looked afterwards. Photobucket - Video and Image Hosting

Inside the rotten bulb

Then I cut the bulb to check on what's going on inside. This is how it looked like...

Oh, that is just terrible, mariava!

Did you actually salvage something from that??? I just don't see anything good there, except for the upper right edge. Can't be certain from the pic.

Robert.


 o
Cuttage...

Then I cut the bulb in five portions making sure each portion has a piece of clean basal plate. I cleaned the inside rotten parts and dusted all sides of the cuttages with sulfur.

Planting...

Hold on Raydio...there's more to see.
Then I plant them using different potting mixes to see which one would work for me: pure perlite, seeding mix w/ vermiculite, MG regular potting mix, pure coco peat and 1/2 coco peat mixed with 1/2 perlite. I used clear plastic containers where I put holes on the bottom so I can see if they need watering and if they are rooting.

mini-greenhouse

Then I placed them in a deli-container to serve as a mini greenhouse for humidity and placed the whole thing in a bright window...no direct sunlight.

Babies

After several weeks, I'm sorry I didn't get to document this part, I got a baby from the cuttage that was planted in pure coco peat and one from the cuttage planted in seeding mix with vermiculite. The rest didn't make it...either rotted or just dried up. Here they are...

WOW. What a post... And you actually took the time to take pictures, then post them and give explanations. :o)

No more sniffing...

Thanks! I just didn't want to give up on that rotten bulb. So I told myself, why not make an experiment or something, document it and share it here. "What to do with a rotten bulb" has always been asked here in the forum. So now, that rotten bulb didn't just give me two babies. It gave hope to people who get into this situation.

RE: rotten bulbs---sniff

What fantastic pics---thank you! :)

After seeing what the inside of your rotten bulb looked like Mariava, I cut mine in half too. Good thing I did, because it was gross in there---worse than yours. Ick. I was able to sliver it up though and get three sections that were healthy, with some good basal plate attached. We'll see if I can get some babies.

Thanks to all who responded, as I really appreciate the lesson in bulb care! :)

Wowsers! Thanks for the great pix of your procedure.

And congratulations on salvaging something from a bulb that one might toss as a lost cause. Brava!

Maria- you've given all of us hope for saving rotten bulbs! Thank you for sharing your success story with us. I do have a question for you: Where can one buy sulfur? I need to add some to the plant medicine cabinet.:) Thanks,

Maria is obviously better at this than I am. I tried this experiment and wound up with complete mush all around. Then I stopped watering and wound up with dry mush.

RE: rotten bulbs---sniff

Thanks guys and your very welcome too! It really gives me so much pleasure to share things with you all.
Growhappy...you can get that stuff in your local agriculture store or coop. Actually you can use it as a dust or make a wet paste out of it and then apply to plant wounds.
Plantguy...I think the trick is in the medium you use. The pure perlite did not retain enough moisture for the cuttage to grow roots/babies thats why it dried up. The one planted in MG regular potting mix rotted maybe because it had some kind of compost in it. The ones planted in seeding mix with vermiculite and pure coco peat gave out babies maybe because it was kinda sterile (no compost in it) and at the same time retained enough moisture for the cuttage to root and have babies. I think the mini-greenhouse helped a lot too in controling the temp and humidity. I always use these in growing my seeds and had 90-95% success.
