Gerbera daisies can be susceptible to aphids, thrips, and other sap-sucking insects. Interplanting with species that naturally repel these pests is a highly effective strategy. Alliums, such as ornamental alliums, chives, or garlic, are excellent choices. Their strong scent acts as a natural deterrent, masking the attractive scent of the Gerbera to many common pests. Similarly, herbs like basil and rosemary release aromatic oils that confuse and repel unwanted insects, creating a protective barrier around your daisies.
Certain plants can improve the overall growing conditions for Gerberas. Legumes like bush beans or sweet peas are beneficial neighbors. These plants have a symbiotic relationship with bacteria that fix atmospheric nitrogen into the soil, making this essential nutrient more readily available for the heavy-feeding Gerbera daisies, promoting lusher foliage and more vibrant blooms. Low-growing leafy greens such as lettuce or spinach can also serve as a living mulch when planted around the base of Gerberas, helping to retain soil moisture and suppress weed growth that would otherwise compete for resources.
From an aesthetic standpoint, companion planting creates stunning visual combinations. Gerberas provide bold, cheerful focal points. Pairing them with plants that offer contrasting forms and textures elevates the design. The tall, spiky blooms of salvia or veronica create a beautiful vertical element behind the mounded Gerbera plant. For a softer look, the airy, filler qualities of baby's breath (Gypsophila) or the delicate sprays of lobelia work wonderfully in both beds and containers. The silvery, fuzzy foliage of dusty miller or lamb's ear provides a stunning textural contrast that makes the glossy leaves and bright flowers of the Gerbera pop.
When selecting companions for containers, consider plants with similar sunlight and watering needs. Gerberas require full sun and consistently moist, well-draining soil. Calibrachoa (Million Bells) and trailing lobelia are ideal for spilling over the edges of pots, complementing the upright Gerbera blooms. The vibrant foliage of sweet potato vine adds a dramatic element of contrast. For a fuller look, compact herbs like thyme or dwarf basil can fill in the base, making efficient use of space while providing the added benefit of pest repellence.
It is equally important to know which plants to avoid. Do not plant Gerbera daisies with heavy, aggressive growers or plants that require completely different conditions. Invasive mints will quickly overtake the container or bed, competing aggressively for water and nutrients. Avoid plants that prefer dry, poor soil, such as many Mediterranean herbs like lavender or Russian sage, as their need for excellent drainage and less water is incompatible with the Gerbera's preference for consistent moisture.
