Using this planter is easy. First, find a suitable spot on your wall or balcony. You can hang it securely or place it stably due to its weight. Fill the 'box' with good - quality soil and plant your favorite flowers or small plants. Make sure the plants get enough sunlight and water regularly. When it comes to maintenance, check for any signs of rust occasionally. If you notice some rust, you can gently sand it off and apply a coat of rust - resistant paint. Also, in harsh weather conditions like heavy rain or snow, it's a good idea to bring the planter indoors to protect it and your plants.
