Crown Rot is in many different crop plants due to lack of Boron. In Aldrovanda some dieing back is supposed to lack the same element.
This might be an issue with Cephalotus and maybe some clones of Dionaea too, just a thought.
As we like to clean with picking dead leafs could be an issue, because this element can’t be retrieved while leafs are dieing
I myself do like to pick all the dead leafs and pitchers from my plants. I had this sudden crown dieing not yet experienced, probably because my Cephalotus experience is quite young, but maybe also due to the fact that I add a few morsels of lime free clay (acid test) to my substrate.
Only very little of boron is needed, but in sandy soil it soon leaches out.
Fired lime free clay can be a source.
Near the sea the inland wind could be a possible source.
Another possible source is decomposing granite, where it is often present.
A very good source is every variety of tourmaline, like schorl, peridot and others. Maybe a little piece in the water will be sufficient for a constant supply.
If lime is present, boron is not accessible for plants, but this is no issue with most carnivores.
Boron is used against insects and I do not know if any and how much they can provide. Maybe it is mostly present in the chitin which is degrading slowly, which might be after the pitchers have died? We usually take all rotten stuff and empty chitin away and might get there this lack of this element.
Boron is needed in traces for the cell membrane in plants. Lacking it, mould and bacteria will have an easy game.
After I found out about "Crown Rot" in non carnivorous plants, I had quite a bit of research to do, but I think it’s worth a try.
Maybe then it will be easier to grow this plant, if this is a limiting factor.
In the species Cephalotus I quite often read about dieing back of a growing center after a flower, experienced by some growers.
So it was no surprise for me that the biggest demand for boron is in the flower. It can’t be retrieved by the plant after it wilted only by decay. This will not happen in our cultured plants.
In some clones of Dionaea I had the symptom that the heart of some plants suddenly turns brown and rots away. After some time there is a lot of small plants in the pot but they take up quite slowly. Maybe some very, very small amount of boron would help.
The species afflicted in agriculture reach from potatoes, onion, legumes and cruciferous plants to even apples.
In agriculture borax is usually applied 20 kg per hectare or boron acid 12 kg each year.
This is of course with our plants too much but I think we should keep in mind this possibility. But it is relatively easy overdone and then harmful to our plants.
I will try with a weak mother solution like some grains to a liter of distilled water and add this to my usually water by some drops during summer, while the rain washes excess away when I overdo.
