I am no expert, but I would say; compost, compost, compost...Good luck.

Mikeymagoo - This forum has a lot of experienced people that can advice you, it would help if you post a picture so we can get some ideas.

I moved to this house 3 years ago and all I had in the backyard was a lawn. Little by little I have been adding raised beds to the garden and fruit trees.

And this is how it looks now

Before you start anything and you want to be successful you have to make a plan and amend the soil. Sandy soils have no nutrients and maybe nematodes.

Once you have your set-up in place, you have to think about what you would like to grow.

You have a big job ahead of you and clean up is number 1, good luck with your new gardening adventure!

mikeymagoo27- What do you want to grow?

The easiest way would be to buy the raised garden kits they sell at the box stores. You could always make your own, if you're handy.After you set it up, cover the lawn/weeds with several thicknesses of newspaper, then add your soil.You can buy the soil by the bag or by the truck load.
You could start seeds inside your house or wait until it gets somewhat cooler and plant store bought seedlings...say end of Sept.
While you're waiting, think about irrigation and what you want to plant.
