I have a few bottles of ground cinnamon andI I'm thinking of sprinkling some on the soil of my potted sansevieria. Middle of the rainy season here, and I'm reluctant to use chemicals. Anybody with experience on this?

Yes, I do use that but not on the roots, just on the leaves, when I get cuttings or maybe on the stems to cover the open 'wound'

Just adding: My understanding with Sans grown in the Philippines, they survive very well there even months submerged planted in ground even if the soil is in our traditional loam soil there.

I would just pull them in for now (those in containers), since some of your Sans are still quite young. There is just too much moisture in the air and everywhere there. Unless the sun has finally come out, then let the sun dry them out fast, till the next bout of the monsoon comes in.

I've heard that cinnamon is used as an anti-fungal because it repels water (hence not putting it on roots as tarev said). If placed on roots, it'll keep them from absorbing water. I'm not sure what effect it would have by putting it on the soil to be honest. Tarev has good advice on this one.

Spitz,
I use power sulfur. This lowers the ph and fungus dies and the Sans love a lower ph. Sans can go down to 5 and I don't think power sulfur goes that low. 6 is the best alround ph for Sans. I mix mine in water then use it to water all my Sans. It stops crown rot and even started to see pups starting to come up.
You can buy 'Flowers of Sulfur' or just sulfur for Rose Gardens.

Thanks!

I have seen Sans growing in bog conditions in Puerto Rico. They had hurricanes and many months after they were sitting in water. They were hacking them down because they were growing so thick. Pretty much told me you cannot drown them that is for sure.

Cinta,
It is always the common ones that you cannot kill. Those beautiful variegated ones die if you stare too long at them.
I too have seen S. tri. hahnii in a flowing spring in tropial contitions. Gold hahnii will not.

These are the ones that grow in my mom-in-law's place in Manila, veterans of monsoon floodings there: at the height of the flash flood in 2009, the water breached half way that iron gate fence, so even the lower floor of the house got inundated, and by that level, all those Sans were fully submerged for about a month. To be able to go out of the house, temporary wooden planks were built, othewise you wade in waist deep water on the road. It used to be floods only reach the first step of the cement entryway, that horrendous flood was just a nightmare. Anyhow, just telling this to show how much water these Sans can truly take. I think the temperature is warm enough for it, so it does not make it hard for the plant to continue surviving. But most of their other plants died..so on my most recent trip home, I see most homes around, they just grow this more, afraid another inundation will wipe out their plants, or if not in containers easy enough to reposition elsewhere if there is space.

Cinnamon is used by many orchid growers as an anti-fungal agent. I sprinkle a little on other plants too -- plant roots when dividing or cutting them apart or leaf cuts. I even sprinkle some on the surface of potted plant if you notice ants -- they don't like it and will move. Might need a couple of applications. No need to apply a lot, just a light sprinkle. For my garden I buy the cheaper dollar store jars of cinnamon.
