This tip comes from Jerry Baker, who has an amzing number of books on how to use household items in the garden.
He claims that burying a match book under a pepper plant will make the soil more acidic-via the sulphur in matches-which in turn makes for a happier plant.
I'm not sure that my soil isn't acidic already, considering the amount of peat in the potting soil of my raised beds, but I'm curious and want to give this a try.
I have 2 bell peppers growing in a corner of my raised bed. They came from the same 6 pack, and were planted at the same time (about 10 days ago).
I'll follow up with results during the season.
Be well and happy gardening.
