What to Plant with Gladiolus: Creating a Stunning Summer Garden
Gladiolus, with their vibrant, spiky blooms, are a summer garden showstopper. But planting them effectively means considering companion plants that complement their needs and enhance the overall beauty of your flower bed. Choosing the right companions can prevent overcrowding, improve soil health, and create a visually appealing display. This guide will help you select the perfect plants to partner with your gladiolus.
What are the best companion plants for gladiolus?
The ideal companions for gladiolus are those that don't compete for the same resources (especially nutrients and water) and offer visual contrast. Good choices often have different heights and flowering times to create a layered effect that lasts throughout the summer. Here are some top contenders:
-
Low-growing annuals: These plants fill in the gaps between the gladiolus corms, preventing weed growth and adding a burst of color at the base. Consider low-growing zinnias, marigolds, lobelia, or alyssum. Their shorter stature won't overshadow the gladioli, and many offer pest-repelling properties.
-
Taller plants with contrasting textures: Plants with different foliage textures offer visual interest. Consider feathery ferns or grasses like ornamental grasses (like Stipa tenuissima), or plants with broad leaves like hostas (planted further back). These provide a contrasting backdrop for the gladiolus's spiky blooms. Ensure that these taller plants aren't so tall that they shade the gladiolus significantly.
-
Plants with complementary colors: Choose plants with colors that either complement or contrast with your gladiolus. For instance, if you have red gladiolus, consider pairing them with blue salvia or white daisies for a vibrant contrast. Harmonious pairings can also be striking; planting shades of pink and purple together can create a romantic and cohesive feel.
-
Bulbs with staggered bloom times: Planting other summer-blooming bulbs can extend the visual appeal of your garden. Consider dahlias (though they may need more space), lilies, or even late-blooming tulips for an extended period of flowering. Choose bulbs with different heights and bloom times to ensure a continuous display.
What should I avoid planting with gladiolus?
While many plants make excellent companions, some should be avoided:
-
Heavy feeders: Gladiolus need well-drained soil rich in nutrients. Planting heavy feeders nearby can cause competition for resources, leading to weaker gladiolus blooms. Avoid plants known for their voracious appetites, like large sunflowers or some types of squash.
-
Plants prone to the same diseases: Gladiolus are susceptible to certain diseases. Planting plants prone to the same fungal or viral infections can increase the risk of infection spreading throughout the entire bed.
-
Overly aggressive spreaders: Avoid planting aggressively spreading plants that could quickly overgrow and choke out the gladiolus.
How to plant gladiolus and their companion plants?
The success of your gladiolus and companion planting relies on proper spacing and preparation.
- Soil Preparation: Ensure the soil is well-drained and enriched with compost or other organic matter.
- Spacing: Give gladiolus corms ample space, generally 4-6 inches apart, depending on the variety. Plant companion plants according to their mature size, leaving enough room for each to thrive.
- Planting Depth: Plant gladiolus corms with the pointed end facing upward. The depth should be about 4-6 inches deep.
- Watering: Water consistently but avoid overwatering, which can lead to rot.
- Staking (if needed): Taller gladiolus varieties may require staking to prevent them from flopping over.
By following these tips, you'll create a stunning summer garden filled with the vibrant beauty of gladiolus and their perfectly chosen companions. Remember, careful planning and observation will ensure a successful and visually appealing planting scheme.
What are some low-maintenance companion plants for gladiolus?
Many low-maintenance annuals and perennials make excellent choices. Consider drought-tolerant plants like dianthus, coneflowers (depending on your climate and available space), or lavender. These require minimal watering once established and add a touch of elegance to your gladiolus display.
Do companion plants help protect gladiolus from pests?
Some companion plants, like marigolds and calendula, are known for their pest-repelling properties. While they won't guarantee complete pest protection, they can help deter certain insects, potentially reducing the risk of damage to your gladiolus. However, diligent monitoring and necessary pest control measures remain important.
When should I plant gladiolus and their companion plants?
Gladiolus corms are typically planted after the last frost in spring. The timing for companion plants depends on their individual needs; some annuals can be sown directly into the ground after the last frost, while others may require starting indoors earlier. Check the specific planting instructions for each chosen companion plant.
