Modern Planters

Almost any plastic container can be used to create glamorous concrete planters using this easy DIY guide – decorate your garden beautifully!

What you will Need for your Planters

  • Plastic containers in a variety of shapes and sizes
  • Releasing agent (e.g. oil)
  • Cement
  • Fine river sand
  • Masking tape
  • Primer
  • PVA paint


Builder’s bucket, trowel, paint brush, drill and masonry bit, scissors


  1. The first step is to make the moulds. You will need a container in an attractive or interesting shape, and the right size for the pot you have in mind. If necessary, cut the top off the container. Spray or wipe the interior with a releasing agent. You now have a mould.
  1. Mix together 1 part cement, 3 parts fine river sand and enough water to make a concrete mixture that can pour easily. Pour the mixture into the containers.
  1. Put some sand in a smaller container that will provide a big enough cavity to plant in. Rub or spray releasing agent on the outside of the container and press it into the concrete. Leave the planter to cure for a few days.
  1. Remove the container from the planter and then remove the planter from the mould. Allow the concrete to dry for a few more days.
  1. To add some glamour to your pot, choose a brightly coloured or contrasting paint. Mask off a neat band on your planter and paint the concrete with a primer. Allow it to dry and then paint a further two coats in your chosen colour, allowing the paint to dry fully between coats.
  1. To ensure your plants don’t get wet feet, drill a drainage hole at the bottom of the planters. Plant up and position in pride of place.
