DIY Concrete Planter : Create a unique garden planter using concrete, cooking spray and your choice of forms.
Gather your forms (we used 3- and 5-gallon buckets). Use cooking spray to coat the inside of the large bucket and the outside of the small bucket.
Mix concrete in a tub (wear rubber gloves and a mask) following package directions.
Pour the mixture into the large bucket to about the halfway mark. Slide the small bucket into the center of the large bucket and push down to within 2 inches of the bottom.
Use bricks, stones, or sand to weight the small bucket. Secure the weighted small bucket with duct tape so it doesn’t rise.
Remove the weights after 48 hours. Slit the inside of the small bucket and remove. Slit the outside of the large bucket and remove.
Use a masonry bit to drill a hole in the side or bottom of the container for drainage.
