This is a fun little video of 18 minutes duration that both shows how to grow a nice crop of basil at 58 North in winter with a couple of grow lamps and some aluminum foil on the wall; and shows the power of binary exponentials.
Basically he starts with your typical over planted store cube of basil that isn’t doing well, takes cuttings from the tops to root, plants them out one to a cup, and repeats the process 30 days later. At the end of 60 days, he’s not only had a nice crop harvested, but has more basil plants than you would need unless you are really fond of pesto.
I’ve got a small patch of basil where I just planted it out into the garden today. I was thinking it was maybe a few to few plants (only one 1 quart styro-pot of seeds started) and was thinking I’d need to plant some more seeds. Now I’m thinking maybe not, I can just take some cuttings and root them.
There are many vegetables where cuttings can be used. It isn’t a common food garden technique, but I don’t know why. Seeds or commercial pots seem to dominate the space. This video has encouraged me to give it a try, as I do like too much pesto ;-)
FWIW, in another video they mentioned that a few drops of vinegar in the rooting water helps stimulate root formation. Though from the looks of it, basil doesn’t need much encouraging!
I’ve decided that since most of my outdoor leafy plants get hit with some kind of bug or another (the chard especially is a leaf miner magnet) that I’m going to do some indoor hydroponics. Eventually. This looks like an easy way to get started with indoor growing then move to a hydroponic tub later.
