1. Research the types of plants you would like to grow in your garden and decide on a design layout.
2. Determine the size of the garden based on the amount of space you have available.
3. Prepare the soil by eliminating any weeds and testing the pH of the soil to make sure it's suitable for the types of plants and flowers you have chosen.
4. Add any soil amendments if needed and rake the soil to create a level surface.
5. Install a watering system to provide irrigation to your plants.
6. Plant your chosen plants and flowers, making sure that each plant is placed in the right position and has enough space to grow.
7. Mulch the soil around the plants to help keep moisture and control weeds.
8. Fertilise the plants regularly to ensure they stay healthy and vigorous.
9. Monitor your garden for pests and diseases and take action if needed.
10. Maintain your garden by weeding, pruning and deadheading your plants.
