Concrete spheres

Having a Ball

    Concrete spheres bring lasting beauty to any garden. Cast a half sphere at a time, using 10-, 12-, or 15-inch-diameter molds. Sandwich two halves to make a round with a spread of mortar holding the pieces together. Dabs of outdoor acrylic paint add a mossy appearance that becomes even more realistic with weather and age.

On the Edge

    Plant some personality in your garden using concrete edging. It stands up to all kinds of weather and helps keep soil in beds, lawn and weeds out. Start with a concrete mold and a bag of extra-strength, fiber-reinforced concrete mix. Customize your creations with concrete colorants.

The Right Steps

    It's only natural to enhance your garden with leaf-shape stepping-stones. We used a large rhubarb leaf as a guide for sculpting these stepping-stones and completed a pretty, sure-footed path through the garden in a couple of hours. Resulting in a total cost of less than $20.

Step 1

    To do this project yourself, start by planning a path of staggered steps matching your stride. Carve each leaf-shape hole about 3 inches deep.

Step 2

    Lay a 1-inch drainable base of pea gravel topped by inch of coarse sand in each hole.

Step 3

    Prepare the concrete, adding water slowly to half a bag of quick-setting mix (meaning it starts hardening in about 15 minutes).

Step 4

    Blend the concrete with a hand trowel until it is thoroughly moist and resembles chunky peanut butter.

Step 5

    Fill the hole evenly with concrete. Use your hands to press and sculpt the concrete into a leaf shape.

Step 6

    Place a rhubarb leaf vein-side down on the surface of the concrete. Press firmly to make a detailed impression. Lift off the leaf.

Step 7

    Enhance the veins, if you like, by deepening them using a wooden skewer.

Step 8

    Cover the stepping-stone with damp burlap. Keep it covered and damp to help strengthen the concrete while it cures for a week.

Bowled Over

    Here's a use for those lidless plastic storage containers: Make lightweight hypertufa pots (click here for instructions to make your own hypertufa mix) -- ideal for succulent plants.

Plastic Perfection

    Use pairs of slightly different-size containers to shape your pots. Before the concrete sets, poke a drainage hole with a cork.

For the Birds

    A simple basin settles easily into the garden's edge where feathered friends can drop in to drink, splash, and bathe. Form your birdbath in the garden by scooping out a shallow hole, shaping a 15-inch-wide and 3-inch-deep mold in the soil. Press bits of tumbled recycled glass into the surface of the still-wet concrete for a touch of sparkle.
