Well, I don't know if it's easier to grow food than buy it. It is A LOT of work. Takes quite a bit of vigilance to protect fruits and veggies from the weather, the insects, the birds and the mice. On that last one, however, I've been blessed with a garter snake or two that keep the mice population down. I first found one when I accidentally picked it up while grabbing a handful of top-heavy basil in bloom. Eeeccckkk! My first instinct was to chop him with a shovel (I know...bad...bad...bad...but it scared me!). It slithered off with my scream and I've since noticed a couple more. We're trying to live together in harmony. But I now poke stuff with a stick before sticking my hands down to the goodies. HA!
Despite being a lot of work, one li'l experiment convinced me to grow my own fruits, vegetables and herbs. I'd read the label of Fit Fruit Spray in the produce aisle and realized concentrated lemon juice would also do the trick of washing and cleaning fruit. So just out of curiosity, I purchased some Chilean grapes, knowing full well that they don't always follow the strict guidelines of the FDA and EPA when it comes to the use of harmful chemical pesticides such as Alar. So I put the grapes in a colander with a recovery bowl beneath, sprayed them heavily with lemon juice and let them sit. I checked the recovery bowl about 30 minutes later to find a blackish-brown liquid that no longer smelled like lemon juice. Yum!
I won't get into the recent E.coli outbreaks caused by U.S. commercially-grown spinach, but it's just one more argument for giving the ol' green thumbs a good workout.

Gardening IS work, but it has its just rewards. I still buy Chilean grapes, BTW. And before they hit the table, they're the cleanest grapes on the planet, let me tell ya!
