Divide Your Gladiolus Like a Pro: The Ultimate Guide to Multiplying Your Beauties

Gladiolus, with their vibrant and majestic blooms, are a beloved addition to any garden. To ensure their continued health and vigor, dividing gladiolus is crucial. This process allows for the rejuvenation of the plant, the propagation of new plants, and the prevention of overcrowding. In this comprehensive guide, we will delve into the step-by-step process of dividing gladiolus, empowering you to effectively care for these beautiful flowers.

When to Divide Gladiolus

The optimal time to divide gladiolus is in the fall, after the foliage has died back and the corms have matured. This allows them to establish a strong root system before the onset of winter.

Materials Required

• Gladiolus corms
• Sharp knife or spade
• Clean containers
• Peat moss or sand

Step-by-Step Guide

1. Dig Up the Corms:

Carefully dig up the gladiolus corms using a spade or fork. Avoid damaging the corms by using a gentle touch.

2. Remove the Foliage:

Trim off any remaining foliage from the corms. This will help prevent disease and allow for better air circulation.

3. Separate the Corms:

Break apart the corms into individual units, each with its own basal plate. Use a sharp knife to carefully cut through the corm if necessary.

4. Inspect the Corms:

Examine the corms for any signs of disease or damage. Discard any soft, discolored, or damaged corms.

5. Dry the Corms:

Spread the corms out in a well-ventilated area to dry for several days. This process helps prevent rot and ensures healthy storage.

6. Store the Corms:

Store the dried corms in clean containers filled with peat moss or sand. Keep them in a cool, dark, and dry place until spring.

Planting the Divided Corms

1. Prepare the Soil:

Choose a sunny location with well-drained soil. Amend the soil with compost or manure to enhance fertility.

2. Plant the Corms:

Plant the corms with their pointed ends facing upwards. The depth should be approximately twice the height of the corm.

3. Water the Corms:

Water the corms thoroughly after planting. Keep the soil moist but not waterlogged.

Care and Maintenance

• Water regularly, especially during hot and dry weather.
• Fertilize monthly with a balanced liquid fertilizer.
• Stake tall varieties to prevent them from falling over.
• Remove spent blooms to encourage new growth.

Benefits of Dividing Gladiolus

• Rejuvenates the plant and promotes vigor.
• Prevents overcrowding and competition for nutrients.
• Propagates new plants, saving money on purchasing new bulbs.
• Improves air circulation and reduces disease susceptibility.
