Update: Things continue to look good in my opinion. Everything is 'firm.' No mold. No mushiness. The black has not moved. Here is hoping.

Update: Down on the green skin - firm. Up near the cut - a little soft. On the actual cut - generally firm.

All I can do is wait and watch.

Should I add more sulfur powder to the top? It looks completely covered but I worry.

Update: The black has not moved or changed. I am trying not to get my hopes up, but it is looking a little more like the photos of cuttings I have seen.

I remain patient.

I figured as much. He lived in the house with me for 23 years but getting knocked off the windowsill let the fungus in.

I am not giving up, but I am also setting myself realistic expectations that he probably won't make it.

Trying to attach photos again resized.

Seems like it will go this time.

Hello everyone!

I don't think this is right. There is a line of black all around the edge and it is a little soft.

Do I try again?

Thank you.

It is not letting me post additional pictures. I tried starting a new thread, but I am getting the same "attachments maximum" error.

Hello! I have (hopefully) done this properly. I used a alcohol sterilized knife to cut above the topmost black spot. I then placed him grow point down in a pot I just bought and supported him with little stones. I applied the sulfur across the cut. I will now put him back on the windowsill (indirect...

Is there a minimum height the cutting needs to be? I worry I am cutting him "too small". How long/tall should the cutting be? I just read 1-2 inches tall is sufficient but I want to make sure that is accurate? If possible, can I cut him into multiple "slices" for more chance of s...

Thank you everyone for your support! I am not giving up. I am working on getting the sulfur powder now. Should I cut the end off where the cinnamon was to get to a 'clean start' or wash it off. Also, I see a few dark areas I am worried about. Should I cut them out while they are small and put sulfur...

Thank you for the reply. I made sure to cut until all flesh was clean, white, and all edges were healthy green. I am watching it to make sure the edges do not turn soft/ brown or black and I am keeping him in a dry place with indirect sunlight. How will I know when the callus is ready? Will it be fi...

Please help! I live in South Florida and my friend from Arizona gifted me a saguaro 23 years ago (Spike). I have taken pretty good care of him and he was getting tall. A few weeks ago, the cat knocked him off his windowsill. He cracked and dented and went on to get a black fungus. His lower body and...
