What does the aspirin do?

Click to expand...

Not sure of the action, but it’s known to keep cuttings fresher longer. If you’ve ever bought cut flowers and such, they usually have a little baggie that says “add this to the water in the vase”

What’s in the baggie is aspirin powder.

The active in aspirin is salicylic acid. Plants have a salicylic acid pathway, that when switched on acts as a defense pathway in the plant. By switching on this pathway you induce a stress response which results in higher essential oil production. That's the very simple version - for more info google salicylic acid and plants.
