Thoroughly protect skin and clothing. Wear protective gloves and a protective respiratory mask when working with concrete.
Choose a nicely sized rhubarb leaf with a nice shape and cut off the stem.
Shape a little mound of soil or gravel and place the leaf on top of it, with the veins of the leaf facing up. The purpose of the mound is to give the leaf a bowl shape, so you can use the finished concrete leaf as a bird bath, fruit bowl or similar.
Combine the concrete according to the instructions on the package.
Cover the leaf with a layer of concrete that is a couple of centimetres thick. Work from the centre and outwards. Avoid getting any concrete beyond the edges. Pat the concrete to spread it out and smooth the surface. Finally, flatten the top so that the leaf can stand stably later.
Spray the concrete with water a few times on the first day, and then let the leaf set for a few more days.
Turn the concrete leaf over and fill it with water. Let stand for a while and then brush off any leaf remnants with a dishwashing brush.
Make an oasis for little birds with a beautiful concrete leaf! Here, we show you how to cast a bird bath using a rhubarb leaf. It's important to shape a good mound of soil or something similar so that the bird bath has a nice shape for the birds to bathe in, and for sitting on the edge. Your garden will be filled with birds ready for a nice, cool dip, and you can sit back and enjoy the peaceful songs of your visitors.
NOTE: It is best to mix concrete outdoors because of the dust it gives off. Find a shady spot out of direct sunlight so the concrete does not dry too fast and crack.
