Growing Non-GMO Mardi Gras Mixture Gladiolus Bulbs

Gladioli thrive in full sun, so select a location with at least 6-8 hours of sunlight daily. The soil should be well-draining; soggy soil can cause the corms to rot. If your garden soil tends to retain too much water, consider planting in raised beds or adding sand or organic matter like compost to improve drainage. Before planting, work in a balanced fertilizer to support healthy growth. Gladiolus prefers slightly acidic to neutral soil with a pH of 6.0–7.0. Get a soil test done and follow the recommended amendments if needed.

Wait until the danger of frost has passed and the soil temperature has warmed to at least 55 F. Dig holes 6-8 inches deep and place each corm with the pointed end facing up. Space corms about 4-6 inches apart. Cover with soil and water thoroughly to help settle the soil around the corms. For a prolonged bloom season, plant corms every 1-2 weeks from spring through early summer. This staggered planting ensures fresh gladiolus spikes to enjoy in the garden or cut for arrangements over several months. Gladiolus blooms 10-12 weeks from planting.

Gladioli need consistent moisture but dislike soggy conditions. Water deeply once a week, providing about 1 inch of water, and adjust during dry spells. Mulch around the plants to help retain moisture and reduce weed competition. As gladioli stalks grow tall (up to 5 feet), they may become top-heavy, especially in windy conditions or when flowering. Use stakes or flower supports to prevent them from falling over. Tie the stems loosely to the stakes with twine or garden ties. Feed gladiolus plants with a low-nitrogen fertilizer once shoots are about 6 inches tall and again when flower spikes begin to form. Too much nitrogen can cause floppy foliage and fewer blooms.

In USDA zones 3-7, gladiolus corms won't survive freezing temperatures and must be dug up in the fall. Wait until the foliage has turned yellow and died back naturally, usually about 6-8 weeks after blooming. Dig up the corms, taking care not to damage them. Remove loose soil and cut the foliage back to 1-2 inches above the corm. Allow the corms to cure in a warm, dry, and well-ventilated area for 1-2 weeks. Once dry, remove any old, shriveled corms attached to the base of the new ones. Store the healthy corms in a cool, dark, dry location, such as a basement or garage, in mesh bags or cardboard boxes filled with peat moss or sawdust. Check periodically for signs of rot or pests.

Mardi Gras Mixture Gladiolus Bulbs in the Flower Garden

The Mardi Gras Gladiolus Mixture is primarily used in the landscape to add vertical interest and vibrant color to flower beds and borders. Its tall, striking flower spikes make it an excellent focal point in garden designs. When planted in groups, they create a dramatic backdrop for shorter plants and can be used to line fences or walkways, enhancing the overall aesthetic appeal of the garden. Their diverse color palette complements various garden themes and plant combinations.

Harvesting Mardi Gras Mixture Gladiolus Bulbs

To harvest Mardi Gras Gladiolus for cut flower arrangements, wait until the first two or three flowers on the stalk have opened while the remaining buds are still tight. This timing ensures the flowers will continue to open sequentially in a vase, maximizing their visual appeal and lifespan. Harvest early in the morning or late in the evening when temperatures are cooler, as this helps preserve the flowers' freshness. Use a sharp, clean knife or garden shears to cut the flower spike at the base, leaving at least three to four leaves on the plant. Retaining foliage allows the corm to continue photosynthesizing and storing energy for the next growing season.

Mardi Gras Gladiolus blooms are perfect for tall, dramatic arrangements due to their striking vertical form and vibrant colors. To use them effectively, pair them with complementary flowers like dahlias, lilies, or greenery for balanced designs. Remove foliage below the waterline to prevent bacterial growth and extend the vase life. Place the stems in clean, lukewarm water with a floral preservative immediately after cutting. As gladiolus stems are naturally heavy, ensure arrangements are supported in sturdy vases to prevent tipping. For field-grown plants, install stakes or grow them near a supportive structure to keep flower spikes upright and in optimal condition for cutting.

About Mardi Gras Mixture Gladiolus Bulbs

The genus Gladiolus derives its name from the Latin word "gladius," meaning sword, a reference to the plant's sword-shaped leaves.

Native to South Africa, gladioli were introduced to Europe in the 18th century and have since been hybridized extensively to produce a wide range of colors and forms. The Mardi Gras Gladiolus Mixture is a result of such hybridization efforts, aiming to create a vibrant blend of colors reminiscent of the festive Mardi Gras celebration.

While gladiolus plants are primarily grown for their ornamental value, it's important to note that all parts of the plant contain compounds that can be toxic if ingested, particularly to pets and humans.

You may have noticed that this page refers to the roots as bulbs and corms. Technically, they are called ‘corms’. However, many people know them as bulbs, so we have used both terminologies.
