Transform your garden into a tranquil retreat by incorporating colorful elements. Paint a wooden bench or a pergola in bright and cheerful colors like yellow, blue, or pink. Hang colorful wind chimes that create soothing sounds as the breeze passes through. Plant a variety of colorful flowers like roses, daisies, and tulips to add vibrancy to the space. Create a cozy seating area with colorful outdoor cushions and throw pillows. Add a small table to hold books or a cup of tea while you relax and meditate.
