Creating your own large concrete planters can be a rewarding DIY project that transforms your garden or patio without breaking the bank. With the right materials and a bit of know-how, you can complete it in just one weekend.
Materials Needed:
- Quick-setting concrete mix
- Water
- Two plastic containers (one larger for the outer mould and one smaller for the inner mould)
- Cooking oil or a release agent
- A mixing bucket and trowel
- Sandpaper
- Paint (optional for finishing touches)
Step-by-Step Instructions:
Day 1: Preparation and Mould Creation
-
Select Your Containers: Choose two containers, one larger than the other. The larger container will be the outer mould, while the smaller one creates the hollow centre where plants will reside.
-
Prepare the Moulds: Coat the insides of the containers with cooking oil. This will help release the concrete once it’s set.
-
Mix Concrete: In your mixing bucket, combine the quick-setting concrete mix with water according to the manufacturer’s instructions. Aim for a thick, workable consistency.
-
Pour the Concrete: Fill the larger container about halfway with the mixed concrete. Then, insert the smaller container into the centre, pressing down to create space for soil and drainage. Ensure it’s level and stable.
-
Level and Set: Continue filling the outer mould with concrete until it’s filled, making sure to remove any air bubbles. Smooth the top surface with your trowel.
- Cure the Concrete: Allow the concrete to set for at least 24 hours. This is a crucial step, as it ensures your planter gains the necessary strength.
Day 2: Finishing Touches
-
Remove the Moulds: Once the concrete has fully cured, gently pull away the outer mould and flip the planter over to remove the inner container.
-
Smooth Edges: Sand down any rough edges with sandpaper to achieve a polished finish.
-
Final Customisations: If desired, paint or seal your planter to protect it from the elements and enhance its appearance.
- Plant Up: Fill your new concrete planter with quality potting soil and select your favourite plants or herbs.
And there you have it! In less than a weekend, you’ve crafted chic, sturdy concrete planters that not only enhance your garden but also offer a sense of accomplishment. Happy planting!
