Wow, great tip for rooting. I knew honey was a good one, but never heard of cinnamon for it. Just be aware though that the cinnamon usually sold in the US is not true cinnamon but is actually Cassia. They are different from each other. There are measures you can take to get true cinnamon (which works better on ants I've heard than cassia). BTW, most cinnamon STICKS are still usually cassia! You can look up the pictures to see the comparisons. Then again, cassia is related and has similar properties. Maybe these recommendations were unknowingly made while implementing cassia anyway!
Timmy2Green, you mean BT as in Bacillus thuringiensis, right? I've searched long and hard because of issues with fungus gnats, and it is very expensive to get a strong dose. I'll let you in on a secret though ; ). Look up this stuff called Microbe Lift BMC. You can find it for anywhere between $15 and $25 and it is SUPER concentrated. It is sold in the pond/water garden market to treat for mosquito larvae, so each tiny bottle can treat around 500 gallons! Literally, you can put just a few drops in a gallon of dechlorinated water for your plants.
