Title: Increasing drought tolerance with vinegar
Post by: Psylocke on June 27, 2017, 10:11:14 PM

Some very interesting new research. Looks like it could be very useful for those of us who grow tropicals in dry climates. Need to look into it more carefully to understand their application method and concentration used since acetic acid can also be used as an herbicide at high concentration.

Bummer, the full article was accessible for a while but now says you need a subscription. From what I can gather the comparison studies were done at a rate of 10mM which I think works out to about 3 tablespoons of 5% vinegar per gallon applied to the soil when the plants were seedlings. Seems that it alters the plant epigenetically so that the drought resistance persists even after application stops.

Amazing! No more expensive jasmonate foliar sprays necessary!
