Hanging baskets introduce vibrant color and lush foliage to areas with limited space, such as porches, balconies, or small patios. They elevate curb appeal by providing a dynamic cascade of blooms at eye level. Success requires selecting the right plants and understanding the environmental challenges inherent to container gardening. The goal is to create the ideal micro-environment for the selected varieties to flourish throughout the growing season.
Specific Flower Recommendations Based on Light Needs
Full Sun Varieties
For baskets exposed to six or more hours of direct sunlight, select heat-tolerant annuals with a trailing habit. Petunias, particularly the Supertunia series, are popular due to their vigorous growth and continuous blooming until the first frost. Calibrachoa, often called Million Bells, produces masses of small, petunia-like flowers that are self-cleaning, meaning they drop spent blooms without manual removal. This low-maintenance trait ensures sustained color.
Additional Sun Varieties
Verbena is a reliable option for hot, sunny locations, featuring clusters of flowers on trailing stems that drape over the basket’s edge. Bacopa is a resilient plant that produces small white, pink, or blue flowers and functions well as a “spiller” plant, cascading over the rim. These sun-loving plants tolerate the elevated temperatures and quicker soil drying common in suspended containers.
Part Shade Varieties
Locations receiving bright, indirect light or morning sun require plants that tolerate less intense conditions. Fuchsia is a classic shade-loving flower, known for its distinct, pendulous, two-toned blooms that attract hummingbirds. Trailing Begonias, such as Boliviensis or Illumination, provide bold color and excellent texture in lower light. Impatiens are a traditional choice, offering a dense mound of color, though deep shade can inhibit flower production.
Setting Up the Basket: Soil and Structure
The foundation of a successful hanging basket begins with the container and the planting medium. Baskets are typically constructed from plastic, which retains moisture well, or wire frames lined with coconut coir or sphagnum moss, which offer better aeration but dry out faster. All options require sufficient drainage holes to prevent the roots from sitting in water, which can lead to root rot.
The soil mix should be lightweight and specifically formulated for containers, avoiding heavy garden soil which compacts easily and restricts root growth. A quality potting mix composed of peat moss or coco coir provides the necessary structure and moisture retention. Incorporating materials like perlite or vermiculite ensures proper aeration and drainage, preventing the soil from becoming too dense.
To achieve a full, aesthetically pleasing display, many gardeners use the “Thriller, Filler, Spiller” design concept. The “Thriller” plant is the central, upright element that adds height and drama. The “Filler” is a mounding plant that fills in the space around the thriller. Finally, the “Spiller” plants, like those with a trailing habit, are positioned along the edges to cascade over the rim, completing the classic hanging basket silhouette.
Maintaining Health and Vibrant Blooms
Consistent attention to watering is the single most important factor for maintaining a healthy hanging basket, as these containers are exposed to air on all sides and dry out quickly. In hot or windy weather, a basket may require watering once or even twice daily to prevent plants from wilting. The best technique is to soak the soil thoroughly until water freely drains out of the bottom, ensuring the entire root ball is moistened.
Since frequent watering leaches nutrients from the limited volume of soil, a regular feeding schedule is necessary to sustain continuous flowering. A slow-release granular fertilizer mixed into the soil at planting provides a steady supply of nutrients for several months. Supplementing this with a diluted water-soluble fertilizer every one to two weeks ensures immediate nutrient availability, especially during peak blooming periods.
To encourage the production of new flowers, a practice known as deadheading is often necessary, which involves removing the spent blooms. This action prevents the plant from diverting energy into seed production and instead encourages it to produce more buds. Pruning, or pinching back, leggy stems helps maintain a compact, bushy shape and promotes lateral branching, leading to a fuller, more uniform basket appearance.
