You will need the following
- Cinder Block or more depending how many you want to make spray paint Cement or Plaster Resin casting mold coaster style. I purchased mine at Hobby Lobby, but they also sell them at Michaels.
Paint the cinderblock and mold 6 cement or casting plaster coasters Attach the coasters to the cinder blocks using cement or Gorilla Glue
Fill with soil and plantIf you live in an area with a lot of rain and snow I suggest making the pegs out of cement. Since our weather doesn't include much rain I got away with using pottery plaster. It dries very hard and holds up in our sun about the same as resin. Everything eventually gets sand blasted here due to the wind, but we are used to giving painted items touch up.
I began with purchasing a mold that is usually used to make resin coasters. It is available at Hobby Lobby or Michael's. I then created 8 pegs per block and used Gorilla Glue to adhere them to the cinderblocks. The pottery plaster cost me 3 dollars, the mold was 2.50. The paint I used was indoor/outdoor Krylon. Hobby Lobby had a 50% off sale last week on all Krylon products. I used a full can of spray on each block to achieve the rich color.
Gorilla Glue will adhere just about anything and the bond is permanent. It is activated with a little water so you just have to sponge both the cinderblock and the peg before adding the glue. If it foams out around the base of the peg don't worry. It is easily hidden with the paint. Once everything was dry I gave it a last spray coat to seal it all together and put it in the sun to cure for a day. I loosely arranged them in the yard and filled the holes with sandy soil. I then planted cactus. They are in bloom now. It will take a while for them to settle in and start to grow, but they should fill out nicely by next season.
