There’s something especially satisfying about making a garden accent from almost nothing, and these heavy textured patio spheres are the kind of project that looks far fancier than the effort it takes. Using old rubber basketballs as molds and cement as the base, you can create sturdy decorative spheres with a wonderful stone-like finish that sit beautifully in flower beds, on porch steps, or tucked beside a walkway.
I’ve always had a soft spot for outdoor pieces that look like they’ve been around for years, the sort of thing you might spot in an old Midwestern yard between the peonies and the hostas. What makes this version so clever is the little secret ingredient that gives the surface extra texture and character. If you enjoy simple upcycling projects and don’t mind getting your hands a bit messy, this one is very manageable.
Materials
1 rubber basketball, cut into 2 equal halves
Instructions
1. Set your basketball halves open-side up on a level surface, nestling them into soil, sand, or a folded towel so they don’t wobble while you fill them.
2. Rub the inside of each rubber half with a very light coat of cooking oil so the cement releases more easily after it cures.
3. In a bucket, combine the dry cement mix and dry peat moss, stirring until the texture looks evenly blended throughout.
4. Pour in the water a little at a time and stir until the mixture is thick like stiff oatmeal; it should hold its shape in a scoop without turning soupy.
5. Divide the wet cement mixture evenly between the two basketball halves, pressing it down firmly to remove air pockets and to capture the ball’s pebbled texture.
6. Tap the sides of the molds several times with your hand to settle the mix, then smooth the flat open tops with the stir stick if you want the spheres to sit more steadily in the garden.
7. Let the filled molds rest undisturbed until the cement is firm, following the cure time on your mix; for most fast-setting blends, I check them after 24 hours.
8. Peel back the rubber molds carefully and lift out the cement halves, handling them gently if they still feel a little green or cool from curing.
9. Set the pieces aside to continue curing for another 24 to 48 hours so they harden fully before going out on the patio or into the garden.
10. Place the finished textured spheres with the open side down among planters, along a path, or in a flower bed where their weight and weathered finish can really shine.
Variations & Tips
About the secret ingredient: The peat moss is what gives these spheres that old-garden, lightly roughened surface. I’ve found it softens the look of plain cement and makes the finish feel more natural in the landscape.
For a smoother finish: If you prefer a cleaner, less rustic sphere, reduce the peat moss slightly and press the surface more firmly when filling the molds.
For extra-aged character: Let the finished pieces weather naturally outdoors, or brush on a little watered-down plain yogurt to encourage a soft mossy look over time in a damp spot.
Placement tip: These are quite heavy once cured, so I always place them close to where I want them before the final cure is complete. My back has taught me that lesson more than once.
Mold tip: If the rubber feels stubborn during unmolding, make one small extra snip at the edge and peel it back slowly instead of forcing the cement piece out.
Batch tip: Make several at once if you can gather more old balls. A cluster of different sizes always reminds me of the old farm gardens around here, where simple repeated shapes made everything feel intentional and settled.
