In Fine Gardening magazine this month is an article about a spray made from
a plant protein, harpin, that causes plants to grow stronger and bloom
earlier. It is available under the trade name of Messenger.

It appears to spook the plant into rev up its immune system and create a
stronger plant.

Anyone have any experience with harpin? What about using it on orchids?


Thought it might be interesting for this group.


Good growing,
Gene
