The Best Flowers For Pots and Containers
Containers overflowing with colorful flowers can add visual interest to a patio, balcony, or other small outdoor areas, add a welcoming touch to entrances, and create curb appeal without spending considerable money on landscaping. We have all you need to know about the best flowers for pots and containers and how to use them to make brilliant displays.
Types of Flowers for A Wonderful Container Garden
Well-suited flowers for container gardening have specific characteristics that make them better choices than others. Here are some factors that can make a flower a good choice for growing in a container:
Some flowers are naturally more compact and have a minor root system, making them better suited for growing in containers. Plant size is significant if you have limited space or are growing flowers on a balcony or patio.
Flowers that require less sunlight are an excellent choice for containers, as they can be easily moved around to ensure they receive the optimal amount of light. Some flowers, like petunias and marigolds, do well in full sun, while others, like impatiens and begonias, prefer partial shade.
Soil Type and Drainage:
Flowers in containers need soil that drains well to prevent waterlogging, so flowers adapted to well-draining soils are a good choice. Choosing the right soil type for your flowers and adding drainage holes to the container can also help ensure healthy growth.
Watering and Fertilizing Needs:
Flowers in containers require more frequent watering than flowers planted in the ground, so choosing flowers that are okay with a bit of drying out between waterings is essential. Also, certain flowers may require more fertilizer than others, so selecting plants with similar nutrient needs is necessary.
Flowers with attractive blooms, colors, and textures can add beauty and interest to a container garden. Additionally, low-maintenance flowers requiring less pruning may be more practical for container gardening.
The Formula For A Beautiful Flower Pot Display
This formula for beautiful flower pots is the “spill, fill, thrill” method. For well-balanced displays, you select plants that spill over the edges, fill the middle, and provide a focal point or thrill at the center of the pot.
The formula is as follows:
Choose a trailing or cascading plant that will spill over the edges of the pot. These spillers include ivy, sweet potato vine, or creeping Jenny. The size of the spill plant should be roughly one and a half times the height of the pot.
Choose one or more plants that will fill the middle of the pot. These can be mounding or upright plants like petunias, geraniums, or marigolds. The size of the fill plant should be roughly equal to the height of the pot.
Choose a tall or striking plant that will provide a focal point or “thrill” at the center of the pot. It can be a plant like spiky grass, a tall flowering plant, or a large-leaved tropical plant. The thrill plant’s size should be rough twice the pot’s height.
By following this formula, you can create a balanced and visually appealing container garden that showcases the beauty of each plant while creating a cohesive display.
