Ideas for my garden and lawn?

Low wall - paving or Path all around - Low Fence - upside down Bottles on sticks or planted neck down. Fill borders with Flowering Shrubs that are evergreen.................

Get yourself a length of good quality (spend once) landscape fabric And make a border. Cover with bricks or pavers or rocks to separate the areas And hold down the fabric. Or buy the appropriate amount of plastic, metal or wood edging for the garden and whack it into the ground.

Or do both If you choose low-edging.

Hello. There are many materials that you could use two separate yard garden from your lawn. Folks use bricks, cinder block, small fencing, pavers, border edging. It really depends on your preference. We have edging in our front yard with mulch around the bushes and we use pavers in our backyard near our patio. Good luck!
