Hey!

So, my preferred method to prop plant cuts has always been water propagations, and I've had great success with that. however, lately, most plants that I root in water that I then pot up in a potting mix, rot in the next couple of days within being potted up.

What can I do? I chopped up my syngonium albo a while ago and Im delaying potting it up because all the cuttings rooted in water and I really don't wanna lose this plant….

btw, the potting mix that I use is my own mix of soil, bark and perlite.

Thanks!

You are in Brazil, so I can't speak directly to your problem. If you were in the southern USA, as I am, I would quickly comment...Bark--what kind of bark? Around here it's now hard to find any commercial potting mix that is not mostly bark, PINE bark, and many plants absolutely do not like the stuff. Have you changed the bark you are using to plant your rooted plants?

I use orchid bark, but it has happened with different mediums too, my begonia maculata, for example, I potted 2 cuttings that I rooted in water back with the mother plant in the soil mix that it came with from the nursery, so I can't tell you for sure what's in it, but they both rotted too.

Since the process is not new to you, there must be something different happening...
-- more or less watering
-- different water source
-- large temperature difference
-- more or less light
-- different part of the house
-- different fertilizing
-- different bag of orchid bark
-- etc.
If you can't come up with any answers, maybe your orchid bark became contaminated with a pathogen.

I use home made chunky mix for my aroids too. The chunky mix that most people use nowdays was originally published by the Atlanta Botanical Garden and consists of varying amounts of potting mix, pumice or perlite, orchid bark, and sometimes depending on personal,preference chopped coconut husk, charcoal and even expanded clay balls like aliflor or LECA. So there's nothing wrong with your mix, Kim.
I don't water prop. I find it pretty useless myself. I prop either in dirty moss (sphagnum mixed with bark and perlite) or just by sticking the nodes of the cutting into the soil mix. It makes stronger roots right off the bat than water does.
I personally think what is happening is that the fragile water roots your plants have made are suffering damage when they hit the soil mix and are crapping out.

I agree with Gina. I have had bad luck transferring cuttings from water to soil.
