Gibberellic acid

In working on seed germination, discovered Gibberellic acid, or GA3, which is a naturally occurring growth hormone for plants.  Apparently, this can increase germination of difficult seeds, overcome dormancy periods and also have some varying effects on growing plants.

It can also have some effect on frost damage, which is interesting for me since many of my favorite plants are tropical in nature, but I don’t live in a tropical climate.  It might be possible to keep some of these plants alive without the added expense of a greenhouse, which I can’t afford right now.

It’s amazing how much technology is available to hobbyists right now.

A table of recipes, located at California Rare Fruit Growers shows the proper concentrations of Gibberellic Acid for various purposes:
