Growing Non-GMO Dazzling Tangerine 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 water, consider planting in raised beds or adding sand or organic matter like compost to improve drainage. Before planting, work in a balanced fertilizer (such as 10-10-10) to support healthy growth. Gladiolus prefers slightly acidic to neutral soil with a pH of 6.0–7.0. Test your soil if you're unsure, and amend it if necessary.

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 blooms to enjoy or cut 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 lifted in the fall. Wait until the foliage has turned yellow and died back naturally, usually about 6-8 weeks after blooming. Carefully 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.

Dazzling Tangerine Mixture Gladiolus Bulbs in the Flower Garden

The Dazzling Tangerine Gladiolus serves as a striking vertical accent in flower beds and borders. Its tall, colorful spikes make it ideal for creating focal points or adding height to mixed plantings. Additionally, it's excellent for group plantings, providing a dramatic and cohesive display of color.

Harvesting Dazzling Tangerine Mixture Gladiolus Bulbs

Use a sharp knife or pruners to cut the flower spike early in the morning when temperatures are cool. Cut at a 45-degree angle, leaving as much foliage as possible on the plant to help replenish the corm's energy reserves. To maximize vase life, harvest the flowers when the lowest 1–2 florets on the spike have opened and the upper buds are still tightly closed. This timing ensures the flowers will continue to open sequentially, giving you several days of enjoyment.

Immediately place the cut stems in a bucket of lukewarm water and keep them in a cool, shaded area for a few hours to condition them. Gladiolus blooms last 7–10 days in a vase if water is changed regularly and the stems are recut every few days.

About Dazzling Tangerine 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, the Mediterranean, and parts of Asia, gladiolus has been cultivated for centuries. This hybrid cultivar is developed through selective breeding to enhance its striking color and robust growth characteristics.

While primarily ornamental, it's important to note that parts of the gladiolus plant, particularly the corms, are toxic if ingested, causing gastrointestinal discomfort. Therefore, they should be handled carefully, especially around pets and children.

This variety can also be referred to as the "Tangerine Gladiolus" or "Orange Gladiolus” Mixture. These Gladioli grow from corms and produce tall, slender stalks lined with sword-shaped leaves. These stalks are topped with rows of blossoms that open from the bottom up, ensuring a long-lasting display.

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.
