Tips for Creating a Beautiful Flower Garden
Design your prettiest garden with our tips for using your plants in the best ways for your landscaping style.
Pick the right flowers: Make sure you understand the watering and sunlight needs of the types of blooms you choose, so they work well together.
Vary the plant heights: Plants of different heights will create a more interesting effect than choosing all the same-size blossoms. Stagger the plants for visual interest.
Plan for the calendar: Choose flowers that bloom at different times so your garden will be colorful all through the spring, summer, and even into the fall.
Keep it simple: It can be tempting to go overboard and have many different varieties, but sometimes, less is more. A strong showing of a few favorites can be much more impactful than a few plants of many different types.
Add a decorative element: To create a focal point in the garden, include a water feature, a garden statue, a birdbath, or hardscaping.
