I keep reading snippets here and there about brain foods and lucky for us one of the tastiest is the blueberry (I am not personally a fan of oysters, but their good brain food too), but our blueberry row at home needed some help. I had a little encouragement from a friend recently and by encouragement I mean she came over with a shovel and a pick-up truck full of cedar sawdust and started hacking into the blueberry row (I couldn't let her do it all by herself). You see we have neglected it over a few years and it was starting to look like part of the lawn with blueberry bushes as weeds. Well, we fixed that by pulling up the grass and then adding cedar sawdust throughout the row. Blueberries love acidic soil and cedar is just that, it also turns out that weeds don't love acidic soil and take longer to come back, it is a win win kind of situation. We are devising a net system next so when the plants actually start producing those tiny brain boosters we can keep the birds from getting them (we wouldn't want them to get any smarter than they already are!). By the way, blueberries are not too tough to take cutting of and propagate your self. A heat pad, perlite mix and a rooting hormone and in a few months you should have small blueberry bushes. Hardwood cutting are the easiest to root, but soft wood will work.
Another grow your own food to smarten you up (as if you not already, I mean you are growing your own food how much smarter can you get) Kale, Chard, Collards, almost all leafy dark green veggies are intelligence builders and they are so easy to grow and there are some great recipes out there, so I guess there are no excuses.
