C., you are never too late to put something beautiful in that area to perk up the land and have beauty.
But, you know something, I would not even bother planting in that soil. Go to just about any nursery and purchase a couple Half Whiskey Barrels or as many as will fit well in the area. Get as many boxes of baking soda as you have of barrels. Take one box of baking soda per barrel and clean inside well, letting the baking soda sit overnight so it cleans up any residue from each barrel. The next day use fresh water and rinse the barrels out well and let dry. Drill several small random holes to allow water drainage once planted in.
I have planted many ways, ground, small containers, large containers, etc. and what I have found that works well is a mixture of what I call 3 3 3. 1/3 potting soil, 1/3 compost and 1/3 sand. Blend all together and place in the barrels leaving a good amount of space on top.
You now can plant dwarf fruit trees, flowers, veggies, whatever you want or what looks pretty in the area. I would suggest one barrel of wildflowers, 1 or 2 barrels housing dwarf fruit trees, being lemon, lime, etc. These trees will grow fine depending on the area you are in. Any local nursery will have the supplies you need and can also tell you what all the soil will need, how to maintain what you plant and some possibly will take the time to show up and help with the initial planting.
A little tip about using things like Miracle Grow, etc. You can use too much of these things. For instance, if you plant tomatoes and use miracle grow once or twice a week, you are overdoing it. You will have beautiful folage but no fruit or very little. Overwatering can kill a plant same as underwatering. If you have no green thumb, start with planting something simple, like flowers or veggies that's not easily killed off. With a bit of time and patience, you will become someone with that green thumb. Good luck to you.
