some ideas:

You need a plan. The first thing is something to hide the trash cans. Then consider how you will use your yard. My guess would be you want a barbecue area and a sitting area. You might want a play area for small kids, a large area for bigger kids to play soccer. Do you want a carefree border of flowers? Or do you want a higher maintenance garden? So, figure out what you want and where it should go.

Then look up the plants you bought, shade or sun, final height. Then arrange them appropriately.

You can arrange the plants in flower beds towards the border. Install turf or get artificial turf in the middle of the garden. You can also add attractive patio or pergola in the backyard. It looks beautiful and you can enjoy the summer thoroughly.

It looks like you have a larger amount of outdoor space to work with, so we suggest to start thinking about what you want your focal point of the space to be. Fire pits are a natural focal point option. What is the purpose of your outdoor room - entertaining, a quiet getaway, a family spot? Your outdoor space is an extension of your home, so maybe look indoors to see if anything sparks some inspiration, too. Patio furniture would be another aspect to consider. Good luck!
