Concrete Mason Jar Planter

I adore all things mason jar so why not make a concrete mason jar planter? Adding your plants to a concrete jar is the perfect way to add some farmhouse flair to your home. And if I can make one….anyone can!  You can even have mason jar planters in all sizes.

Supplies needed to make a concrete mason jar planter:

• Mason jar mold (you can see more on how to make the mold here)
• Pill bottle
• Stir sticks
• Hot glue and glue gun
• Metal bowl
• Plastic mold sealer
• Maker’s Mix Concrete
• Vegetable oil or cooking spray
• Mixing cup
• Measuring cup

You will need a mason jar mold to get started.  In case you missed it, here is a post on how to make the mason jar mold itself.  The Castin’ Craft EasyMold Silicone Rubber makes the molding process easy.  We molded a small 4 oz mini mason jar but you can use the same technique to mold any size that you like.

You will need to add plastic mold sealer around the bottom of the mason jar mold as shown below.  Then press the mold into the bottom of the metal bowl.  Press well to ensure that there is a tight seal.  NOTE: This is the only product that I found that will work for this project.

You will also need something to make a hole in the planter where the plant will actually go.  I used an old pill bottle.  Use some hot glue to attach it to a stir stick as shown below.  Coat both the outside of your pill bottle and the inside of your mold with vegetable oil.  I used a cooking spray to make this process easier.

Now you need to mix the concrete in your mixing cup.  Measure according to the package directions for a thin mix then add a little more water.  About 1/2 to 1 tablespoon of additional water should work.  I found that this thinner mix worked best with the mold and allowed me to get the fine detail.  NOTE:  You should measure and mix the concrete with utensils that you can throw away.  Start adding your concrete mixture to the bottom of the mold.  Use an additional stir stick to press the concrete into the bottom and sides as you add.

Fill the mold almost to the top and then press your pill bottle into the center.  The mixture should come almost to the top but not quite.  If you have too little, remove the pill bottle and add more.  If you have too much, remove the pill bottle and remove some.  Then press your pill bottle into place once more.  NOTE:  The stir stick on the pill bottle will prevent you from pressing too far into the mold.

Allow to cure completely with the pill bottle in place.  This mix works FAST so be quick when filling the mold.  However, since we made the mix slightly thinner than directed you will need to allow it to cure a bit longer in the mold.  I waited about an hour before removing.  It took me three tries to get the concrete mason jar planter that is shown in the pictures.  I had to get the technique and mix just right.  If your first one fails, just try again!  Remember you mold is reusable so additional tries just involve mixing up your concrete.  You can definitely make this project work.

Once cured, remove the mold from the metal bowl.  Then remove the pill bottle from the mold.  You may need a pair of pliers to loosen and pull free.  Then work the mason jar mold until the concrete jar comes out of the bottom.  Add in dirt and a plant and your concrete mason jar planter is ready to be displayed.

I love the detail that comes from the mold and into the concrete.  It is the perfect little mini mason jar planter!

Be sure to add this project to your must make list as it would make a great gift.  Once it comes out of the mold and you see this beauty, however, you may not be able to part with it.  I know I gasped upon seeing that adorable little Ball logo embedded in concrete.

If you need me, I will be admiring my cute little succulent in a mason jar.
