2. Preparing the Soil for Gladiolus

Gladiolus thrive in well-drained, fertile soil. Here’s how to prepare your garden bed:

• Soil Type: They prefer a sandy loam soil with good drainage. If your soil is dense, amend it with compost or peat moss.
• Soil pH: Gladiolus prefer slightly acidic soil with a pH of 6.0 to 6.5. You can test your soil’s pH with a kit available at most garden centers.

3. Planting Gladiolus Bulbs: A Step-by-Step Guide

Once you’ve prepared your soil, it’s time to plant your gladiolus bulbs. Follow these steps for optimal growth:

1. Depth: Plant gladiolus bulbs 4-6 inches deep, with the pointed end facing upwards.

3. Watering: Water thoroughly after planting to settle the soil around the bulbs.

4. Caring for Your Gladiolus: From Watering to Staking

After planting, consistent care ensures healthy growth and vibrant blooms. Here’s a breakdown of essential practices:

• Watering: Water regularly, especially during dry periods. Aim to keep the soil consistently moist but not waterlogged.
• Fertilizing: Feed your gladiolus with a balanced fertilizer every 2-3 weeks.

5. Preventing Pests and Diseases: Keeping Your Gladiolus Healthy

Gladiolus are susceptible to various pests and diseases. Stay vigilant and take preventive measures:

Your gladiolus will reward your care with stunning blooms. Here’s how to make the most of their beauty:

• Cutting: Cut gladiolus stems when about half of the flowers on the spike are open.
