Came across this article and wondered whether anyone has tried this? http://www.gardeningknowhow.com/garden-how-to/info/using-cinnamon-on-plants.htm

Yes, cinnamon is great in the garden. Steep several tablespoons of cinnamon in a pint jar of rubbing alcohol, Strain and use as a spray on seedlings and cuttings. It kills bugs and stops fungi. I've also applied ground cinnamon to cuttings to stave off mold and rot. No idea if it helped with the rooting or not. But it certainly did not hurt.

heard about the use of cinnamon before, but never tried it. 

Very cool!

Very cool, wonder if you can use it to keep ants off trees, didn't have a problem this year but have had fire ants invade in the past..

I will try this on some cuttings in the next couple weeks.

Interesting. Thanks for posting and I will certainly try it

Ive used cinnamon on a couple rotten spots on a new orchid recently and it stopped it.
Its talked about allot on orchids forums.
Physan is a better idea imho

I had a problem with dampening off fungus last year and cinnamon sprinkled on the soil surface seemed to really help.

Never heard of this.  Will definitely have to give it try.  Thanks.

So far no dampening off or fungus gnats but I am sitting here with a quart bottle of cinnamon so guess its worth giving it a try if I do run into this.  Also cinnamon is the main ingredient in snake deterrents so its not a bad thing to have around.  Love my black snakes and rat snakes but some of the others are less enchanting. I hate being surprised when I am picking berries.

Marianna, thank you so much for sharing this wonderful technique, I will start using Cinnamon for my plants from now on.
Happy New Year :)

Have sprinkled cinnamon on the soil around my veg seedlings for two years now and it does work. Didn't know it could help rooting though, thanks.

As for ants, try sprinkling fresh ground coffee on the ant hills. They love the stuff and take in back into the nest. Not sure how if affects them, but they are soon gone after doing this.

Thank you for the link to the informative article.  Very interesting uses for cinnamon. 

I have used it for a wound dressing and on pruning cuts, and is especially useful on succulents, orchids, and juicy plant tissue to prevent infection.  I sprinkle all pruning cuts with cinnamon to stop the sap flow, and is very useful when pruning figs.  The oozing latex binds the cinnamon to the fresh cut, and the cuts heal quicker.

I wonder if Cinnamon is mixed into potting mediums, if it would kill off Fungus Gnats, Nematodes, etc?

Thanks for posting. I just tried it on two cuttings that were showing very slight signs of mold. I'll let  you know how well it works.

Also, could cinnamon be used preventatively on cuttings? Maybe lightly powder the ends before they go in rooting bags? What do you think?

I read online that cinnamon, plain old drugstore bought hydrogen peroxide, and peppermint tea are good for combating funus gnats that's what made me try it. I had apparently brought two gnats along with my mango tree in the house from the cold.
The war against gnats insued because my fig cuttings were too important to suffer any risk of that sort of pest pressure not to mention the gnats plagued us last season when we brought in a few housplants for the winter. I put the mango tree in the hoophouse, got some yellow sticky traps to get the new gnats chased the ones that weren't stuck yet and dumped DE and then sprinkled cinnamon on top of my soil then drenched the soil with water and hydrogen peroxide (hp).
I also made a spray with, water, hp, peppermint essential oil, and liquid kelp to spray on the soil. Later I left out the peppermint oil and kept the hp, water and liquid kelp. The cutting are doing very well wIth this mix.

So far I haven't seen more than one gnat flying at a time for weeks. My method of catching the one I find is to try and wave it towards the sticky trap or pray and then chase it to catch it. That also has been working well. God loves figs too.

The gnats that I didn't see have been trapped in the yellow sticky traps and my cutting are leafing out without slumping.

Its been since October that I started with the traps and spraying and I've chased and caught like three (again though, not ever seeing more than one flying at a time) and the traps have about two on one and one on the other. Some traps have nothing.
Our grow area is free of flying gnats. My hope is that the waterings with the kelp is making them less susceptible to insect /larvae pressure and the cinnamon leaching down is killing any stragglers.

Thanks for the information, does this help with soil nematodes as well?

John,
Fire ant hills are always a problem in our pastures.  Going to have to see whether coffee grounds are a good deterrent.  Certainly a better choice for a grazing area than a poison. The nutrients they provide certainly cant hurt either. :) Thanks for the tip.

Isn't rust a fungus? If so then spraying fig trees with the cinnamon mixture might help with stopping or slowing down the spread of rust. It could be worth a try.

I am ecstatic about Marianna's advise on Cinnamon, i shook some on lower ends of my cuttings as I took 'em out of the fridge and wrapped them in wet paper towel and dropped them in zip=lock to root. I was thinking well...2 good weeks before I see some white growth here and there. Well, it's the 5th day now and guess what! I count 7 figlets and roots up and down the cuttings. I'm going crazy laughing at it, LOL I'm going to post a pic soon with new Post saying Cinnamon on it.
I think I'm going to water all my fig trees and , heck, all the other fruit trees also with Cinnamon water...see what happens.

Will be looking into using cinnamon to battle gnats and pest.....I have been spraying a mix of dish soap on top of the soil, thinking it may kill some larvae...???? Thanks For Posting this Topic.

Armando, I tried the dryer sheet method of controlling gnats. On the premise that soil stored in the carport was likely to be infected with our local bugs, I put a couple of sheets along the edge of a couple of my pots in my humidity chamber. Had some slow rooting varieties going and it seemed to work. Its something else you might try.

Very good info, I'll try it tomorrow.....

Thanks

I treated my cuttings for rooting with Cinnamon, this is 5 days later

 

  
Before even rooting  the figlets started to pop left and right.
