Hi Bibi! I am also in Zone 5 (Central Indiana) and have a similar property. I was introduced to Permaculture, Food Forests and Edible Landscaping earlier this year and fell in love. I love to garden, especially vegetables, and my two girls (age 2 and 4) love helping and eating the vegetables right out of the garden. While I don't plan to do anything in the front yard (to keep up the typical suburban appearance from the street) except plant some blueberries on the south side of our foundation and some edible greens in the front (mostly spinach since our house faces east and this spot is shaded by the Bradford Pear in our front yard). However, I am currently in the process of turning my backyard into my own private oasis of edible landscaping/food forest. We have a back patio and a good sized oak in the back yard. I planted three fruit trees in late May and will be planting five more this fall. I also plan to plant some perennial vegetables and other guild-member plants next Spring. I've never done much with flowers or herbs, but I built an herb spiral for my wife this summer and we plant to introduce many different types of herbs and flowers next Spring all over the property to introduce beneficial insects and attract other wildlife. We still have some lawn in our backyard for the swingset and some room for the dog, but hopefully my vision will allow my family to enjoy homegrown, organic produce and learn more in the process. I know it will be a few years before anything materializes, but I've already been amazed at how well the fruit trees are growing and they've only been in the ground for two months! I will likely mulch next Spring after planting everything, but I do plan to till up the yard and spread generous amounts of compost this fall. I want to balance the aesthetics of the yard with the time it will take to maintain, so I doubt I will do a full blown forest garden. I will be pruning the trees to keep them at an easily harvestable size (probably no more than 10 feet tall), plus I don't have a whole lot of room, so they will need to be controlled. I will try to take some pictures and upload them for everyone to see, but any advice/help the forum can offer would be appreciated.
