Black spot on Bulb. longiflorum? Female
Default Black spot on Bulb. longiflorum?

Hello, can anyone please shed light on what is happening to my bulbo? I received it from Hausermann on Saturday. It has this large black spot. I watered it well on Saturday since it was bone dry. It site in an indirect southwestern window. Sunburn? Rot?
Thanks
N.

Yes, it mushy.
I hope it is 'only' cold damage, though I received it on Saturday afteroon. I just isolated it & emailed Hausermann. I am observing, took images. I only noticed this spot now, because of its size and this leaf facing away from me due to its placement on the sill. Sad face.

Sunburn and/or insufficient water. They need to stay wet, wet, wet when not in moss.

Thanks ES, I only got it two days ago. I watered it and it has been kept moist. Which is why I am not sure if the culprit is watering.

Also, I will add that the reddish tones to the affected leaf was there, as it is a characteristic of this bulbo according to reference images. My question only pertains to the mushy black spot which has spread across the leaf. Thanks!

It was growing in a very humid greenhouse and probably being watered daily. Now it's in a low humidity home. Bulbos have short roots and not many of them. They need water, water, water.

Okay, I checked and it is not dry, nice and moist. I will water daily. Do I just leave the leaf as it is? Treat it or cut it off so nothing fungal sets in?

I would leave it alone. It will demarcate and fall off. Other people would cut it off.
