I like the idea of coffee powered super frogs :D ;D :D Maybe I should market them???
Loulou, I think it is worth a go. I sprinkled some around the outdoor staging the day before
the whole yard got done this year because it was raining. It seemed to work as my sweetcorn was un-nibbled.
Tricia :-*
For the record, I usually coffee the lottie a couple of weeks before tender plants get put in, and then just coffee around the edges of the beds occasionally (maybe twice a year) during the growing season. I have no idea if I would end up with coffee flavoured tomatoes, but i don't fancy trying it out.
I also don't add coffee to my young seedlings. Again, i don't know if there would be any side effects, but I'm not risking my little plants to find out. I use coffee everywhere else (walls too) and it works for me.
