A path through the garden keeps dirt and mud off your shoes and avoids compacting the soil around the plants. Keep garden beds no more than 4 feet across for easy access to the plants for harvesting, weeding and fertilizing. Use paving and pavers to create patios as well as pathways.
Bricks come in a variety of finishes and colors. Lay the bricks in interesting patterns like herringbone, which resembles interlocking V's made of bricks, basket weave and interlocking boxes which puts the bricks together in pairs at right angles to each other. Lay the bricks in a bed of sand over gravel for stability. If the path or patio is temporary or you just want to try it out, use sand brushed between the cracks rather than mortar.
Most patios have straight edges but that doesn't mean yours has to. Clear out an area under a shady tree and install a circular patio. The stones are made of cement and are shaped to form a circle with one end narrower than the other. Think of a pizza pie cut in wedges with the tips of the slices cut off. Use the pavers to form a border around a curving flower bed or around a tree. With planning it's possible to construct a patio with the inner pavers being straight and the edges of the patio being curved.
Concrete poured as a walkway is one method of using it in the garden, but it's not the only way. If you have an old patio or driveway that's being removed use the broken pieces as stepping stones. Make a path of concrete stepping stones using a form. Mix the cement and pour it into the form on the ground. Wait until it sets. Remove the form and go on to the next part of the path. Ceramic tile laid over a concrete base is used for many patios. What's a little more unusual is to lay decorative tile in the cement before it dries. Place the tiles around the border, in a regular pattern or however you like them. Press the tiles in so they are level with the cement. Do this quickly before the cement sets.
Pre-made stepping stones are available at nurseries and home improvement stores. They come in round, square and octagon shapes. Sizes range from 1 square foot to 18 inches square. Create a checkerboard effect by using stepping stones of two colors. Another idea is to lay the stones adjacent to each other and then remove one randomly throughout the patio. Fill in those missing tiles with grass, if the patio in the sun, or a ground cover like sedum, if the patio is in the shade. Create a design by putting squares of one color in the center of the patio. Surround them with a border of stones in a contrasting color and an edging of stones in a third color.
