I've been working on this. So far I've planted several fruit trees in the front lawn, and I'm planning to gradually plant other things around the fruit trees, so the garden areas gradually spread and take over. Currently the trees are all mulched , so the grass isn't too close to them.
I also have an area between the house and a short retaining wall next to the driveway that is currently planted mostly with perennial flowers, which I'm going to replace with useful plants. This is where most of my annual veggies will grow.
I have to be very careful to avoid the wrath of the lawn police. We don't have any ordinances saying you have to have a front lawn, but we aren't supposed to have any grass or weeds taller than 8". The way the law is written, it doesn't really define what constitutes a weed, so it pretty much means if someone from the Division of Property Standards doesn't like the look of your yard, you get a threatening letter from the
city.
Several years ago we moved out of this house, intending to
sell it. Soon after the city declared it vacant, which meant they could come in and do whatever they wanted to our yard without a warning. Then they wreaked havoc-cut down all the raspberries, mowed the patch of prairies plants, pruned the trees improperly, etc. They left it a mess and then tried to fine us. We didn't pay and they have pretty much left us alone since our attorney (aka my dad) sent them a letter, but I don't think the charges have been dropped altogether. We eventually had to move back because the housing market went bad and we couldn't afford to sell.
Needless to say, we are proceeding with caution in our current
gardening endeavors. The first summer we were back I mostly planted things in containers, and now we're gradually redoing things, which a major focus on making it look pretty, in hopes of avoiding further trouble. I'm carefully choosing veggies that are ornamental, and planting flowers in between. So far, it seems to be going ok- no threatening letters. We shall see.
