    Excellent suggestions from Geoff. Just to add, large leaf species such as bellina and gigantea are prone to crown rot due to thier shape of their leaves. It is a good candidate for mounting. Coming to the rot, I would suggest you can spray 3% Hydrogen peroxide all over the plant and allow it to air dry it and keep the foliage dry till it puts out new leaves.

    Thanks Geoff and Sriram. i didn't realize that the physan could be used in such low concentrations and still remain effective. I guess it makes sense though as it is helping to disinfect the water. I'm going to have to pick up some more hydrogen peroxide. We will see what happens.

    You may be amused (?) to know that H2O2 is now very difficult to buy in UK - it is too easily used by terrorists in bomb-making, I read !

    Wow. We have it taking up a large section of each aisle. Ephedrine is difficult to buy here because it is used to make methamphetamine. You can only buy small amounts and your ID must be scanned and there is a book to sign.

    I can't imagine how it could be used for bombs. I would google it but then it might look suspicious.

    I vaguely remember making hydrogen mini bombs in high school chemistry pre 911 of course. We made them in plastic pipettes and the teacher roped off a length of hallway and lit them and fired them down the hall in a contest. We used a metal that was fairly hard to obtain( and the teacher counted pieces before and after )and hydrogen peroxide among a few other ingredients. It was the metal that was the hard part. Everything else was pretty standard fare at a grocery or chemistry kit.

    H202 decomposes as Oxygen and water so may be Oxygen aids in combustion of some sort.

    I thought that the bellina would be dead by now as it has been two weeks, I used physan and hydrogen peroxide and moved it to a heat mat under artificial not so great light. It was the only place I had to isolate it. I watered it twice with dilute 1:2500 physan 20 water and today gave it another watering at 1:2500 physan with some kelp max. Not sure if it is just dying slowly or rebounding but I will give it a shot. If it comes back I may mount it under a tree in the front yard to see if it will grow there. I thought about treating it again at full strength but didn't know if that might weaken the plant. Name:  IMG_0062.JPG

    I won't. I'm only using the physan in a very dilute concentration. It seems to be necessary in the winter when the plants don't dry out as quickly. I think the key to the bellina is that it loves to be kept pretty warm. The room is 70 F 21 C and the mat is keeping the plant about 15 degrees higher and it seems to appreciate it. It was fine all summer. The fall and winter started its problem.
