Hosta, oakleaf hydrangea and rhubarb all work well.Turn a candidate over before you commit. If the veins are shallow on the back they will be invisible in concrete."},{"number":2,"title":"Step 2: Mix the Concrete","text":"Use a fine vinyl cement patch rather than a general mix. It has almost no aggregate in it, which is what lets the casting pick up fine vein detail.Add water a little at a time and mix from underneath. You are aiming for a Play-Doh consistency that binds together but does not slump."},{"number":3,"title":"Step 3: Shape the Sand Bed","text":"Pile up damp sand to make the mould. Mound it if you want the finished leaf cupped like a dish, or flatten it if you want the leaf flat.Make sure sand sits under every part of the leaf, and spread the bed a little wider than the leaf itself."},{"number":4,"title":"Step 4: Cover the Sand With Plastic Wrap","text":"Lay plastic wrap over the whole sand bed so no sand works its way into the back of your casting.Cut the pieces to fit and smooth them down over the mound. A few folds are fine - what matters is that there are no gaps."},{"number":5,"title":"Step 5: Lay the Leaf and Spray It","text":"Set the leaf vein-side up on the plastic, positioned so the sand extends past the edges all the way round.Coat the back with cooking spray. That is what lets the concrete release cleanly when it is cured."},{"number":6,"title":"Step 6: Pack On the Concrete","text":"Start in the middle and work the concrete out towards the edges, laying it on rather than pushing it thin.Keep the depth even across the whole leaf. If you shove it out to the rim it goes thin there and cracks when you lift it."},{"number":7,"title":"Step 7: Guide the Edge With Your Hand","text":"Hold your free hand against the edge of the concrete as you work so the rim stays defined instead of feathering away.Carry the same guide right around, including the tip of the leaf. This is what gives the finished piece a clean outline."},{"number":8,"title":"Step 8: Smooth It With Wet Hands","text":"Dip your hands in water, shake off the excess and skim the surface to take out fingerprints and ridges.Go gently near the rim so you do not lose the edge you just built up."},{"number":9,"title":"Step 9: Add a Stand If You Want One","text":"Any concrete left over can become a pedestal. Pat it into a small square in the middle of the back of the casting.It will add to the drying time, but it lets the finished leaf sit raised instead of flat on the ground."},{"number":10,"title":"Step 10: Cure, Release and Clean the Edges","text":"Leave it about three days out of direct sun. Some people tent a bin bag over the top to slow the drying and reduce cracking.Lift the casting off the sand, peel the plastic and the leaf away, then run a grill brush around the rim to knock off the rough bits before painting."}],"recipe":null,"lastUpdated":"2026-08-19T15:32:00.847Z","published":"2026-08-19T15:31:56.170Z","license":"CC BY 4.0.
