Geraniums (Pelargonium spp.) are popular for their vibrant flowers and attractive foliage, making them a favorite choice for container gardening. When planted in pots, geraniums can create stunning displays, especially when paired with complementary plants.
Companion planting not only enhances the beauty of your container garden but also promotes healthier growth and deters pests. Here’s a detailed guide on what to plant with geraniums in pots to create a thriving and visually appealing container garden.
Growing Conditions for Geraniums
- Sun or Shade: Geraniums prefer full sun but can tolerate partial shade. Aim for at least 6 hours of sunlight per day to ensure optimal blooming.
- Summer or Winter: Geraniums are typically grown as annuals in most climates, thriving in the warm temperatures of spring and summer. In frost-free areas, they can be grown as perennials.
- Perennial or Annual: While geraniums can be perennial in warmer climates (USDA zones 10-11), they are generally treated as annuals in cooler regions due to their sensitivity to frost.
Best Companion Plants for Geraniums in Pots
-
Petunias (Petunia spp.)
- Benefits: Petunias provide a continuous display of flowers that complement the vibrant blooms of geraniums.
- Growing Conditions: Prefers full sun and well-drained soil. Both plants have similar water and light requirements.
- Aesthetic Appeal: The cascading habit of petunias contrasts beautifully with the upright growth of geraniums.
-
Lobelia (Lobelia erinus)
- Benefits: Lobelia’s delicate, trailing flowers add a splash of color and fill in the gaps around geraniums.
- Growing Conditions: Prefers full sun to partial shade and moist, well-drained soil.
- Aesthetic Appeal: The bright blue or purple flowers of lobelia create a striking contrast with the vibrant blooms of geraniums.
-
Sweet Alyssum (Lobularia maritima)
- Benefits: Sweet alyssum’s fragrant, tiny flowers attract beneficial insects and pollinators.
- Growing Conditions: Thrives in full sun to partial shade and well-drained soil.
- Aesthetic Appeal: The low-growing, mounding habit of sweet alyssum complements the taller geraniums, creating a balanced look.
-
Ivy (Hedera helix)
- Benefits: Ivy provides lush, trailing foliage that enhances the overall texture and fullness of the container.
- Growing Conditions: Prefers partial shade but can tolerate full sun, and it needs well-drained soil.
- Aesthetic Appeal: The trailing vines of ivy add greenery and texture, softening the edges of the pot and providing a backdrop for the colorful geraniums.
-
Calibrachoa (Calibrachoa spp.)
- Benefits: Often called “million bells,” calibrachoa produces small, petunia-like flowers that bloom profusely throughout the growing season.
- Growing Conditions: Prefers full sun and well-drained soil, similar to geraniums.
- Aesthetic Appeal: The trailing habit and abundant blooms of calibrachoa complement the upright geraniums, adding layers of color and texture.
-
Dusty Miller (Senecio cineraria)
- Benefits: Dusty miller’s silvery foliage provides a striking contrast to the green leaves and bright flowers of geraniums.
- Growing Conditions: Thrives in full sun and well-drained soil.
- Aesthetic Appeal: The unique silver-gray leaves of dusty miller add a soft, muted backdrop that highlights the vibrant colors of geraniums.
Tips for Successful Container Gardening with Geraniums
- Choose the Right Pot: Ensure your container has adequate drainage holes to prevent waterlogging. A pot that’s at least 12 inches in diameter provides enough space for geraniums and their companions.
- Use Quality Potting Mix: A well-draining, nutrient-rich potting mix helps support healthy root growth and vibrant blooms.
- Water Consistently: Keep the soil consistently moist but not waterlogged. Geraniums prefer slightly dry conditions between waterings.
- Fertilize Regularly: Use a balanced, water-soluble fertilizer every 4-6 weeks to promote continuous blooming and healthy growth.
- Prune and Deadhead: Regularly prune and deadhead geraniums to encourage bushier growth and more blooms. Remove spent flowers and any leggy or damaged stems.
By carefully selecting companion plants and providing the right care, you can create a stunning and healthy container garden with geraniums as the centerpiece. Happy gardening!
