Hello everyone, this is my first post. My wife and I (+2 children under 4yo) renovated our backyard and have a beautiful old avocado tree that helps set the mood in our backyard but the shade prevents anything from growing in the corner of my property. We’ve laid down real grass in sun exposed areas in order to maximize playing space for my kids however, we don’t know what to do under this avocado tree. We envision an area for having a picnic, small relaxing wooden chairs and a table or just sitting on the ground. We have thought about laying small stones however worry with small kids it will be a maintenance mess and uncomfortable to sit on. Fire pit was an idea but not useful in S Florida.
The next possibility is artificial turf however we’re worried the transition from real grass to artificial turf will look obvious and cheesy.
If anyone has novel design ideas or a way to break up the real grass to artificial grass transition so it doesn’t seem obvious ( when the lawn is long for example) that would be wonderful.

Thank you for any help you can provide!!
