3 worst Orchid diseases - root, stem and crown rot

Among all the problems we might get with our orchids, 3 seem to be the most common and even the worst of them all. So here is a discussion about them, why they affect orchids and how to treat and prevent them as best as possible.

First disease and the easiest one (though not a breeze in the slightest) is root rot. In my opinion this is more of a symptom, since usually roots die of suffocation or toxic medium and then start to rot. In this case we need to unpot the orchid and cut away everything dead, or things will get worse faster and faster. However many orchids bounce back from this quite well, with a bit of set back. However if an orchid is completely depleted of energy this disease is fatal, so make sure you don;t get there. Use good, fresh medium and repot regularly if you have to and don't water more frequently than you should.

Here are some ways I deal with it:

Next up crown rot. This is a more severe disease as it affects the growth point of monopodial orchids, meaning the very top. Orchids that have a completely damaged crown will not sprout any new leaves, so they will stop growing. If the infection is stopped though, they can continue to produce roots and keikis, so this will not necessarily kill your orchid if you spot it in time. Crown rot is induced bu the infection of the crown and the best way to start an infection is to let water pool in the center, so be careful how you water.

Here is how I save my orchids from this disease if I catch it in time:

Lastly, stem rot which I consider the worst of them all. It affects the axis of monopodial orchids, meaning the root formation area can be completely lost, or the crown area as well if the infection moves up. The orchid cannot produce roots from dead tissue, or leaves at the top if the infection is high. keikis are also out of the question, unless they are on the spikes and the area where the spikes emerge is not affected. So many if's and that's not all. How do we treat it if we don;t know where it originates? Not even soaking the entire stem in peroxide can help, if the infection is hidden and protected by the leaf joints. In my experience it is a most likely killer, though some orchid do manage to escape it.

I cannot recommend a tested treatment, but here is what I tried:

These orchids are not doing very well still, so better prevent it than treat it.

Leaf rots are a breeze though, depending where they form :P here's all you need to do:
