Tritonia Mixed Color Flower Bulbs

Growing Tritonia from bulbs (technically corms) is fairly easy if you provide plenty of sunlight and well-drained soil.

1. Planting time

• Cool-winter climates: Plant in autumn.
• Cold climates with freezing winters: Plant in spring after the last frost, or grow in containers and protect from freezing.
• Warm tropical/subtropical climates (such as much of India): Plant during the cooler months (around October–December) for winter to spring flowering.

2. Choose the right location

• Full sun (at least 6 hours daily).
• Well-drained, sandy or loamy soil.
• Avoid places where water collects after rain.

3. Plant the corms

• Plant 5–8 cm (2–3 inches) deep.
• Space them 8–10 cm (3–4 inches) apart.
• Place the pointed end facing upward.

4. Watering

• Water thoroughly after planting.
• Keep the soil slightly moist while the plant is actively growing.
• Do not let the soil become soggy.
• Reduce watering once flowering finishes and the leaves begin to yellow.

5. Fertilizing

• Mix compost into the soil before planting.
• During growth, apply a balanced fertilizer (such as 10-10-10) once every 3–4 weeks.
• Stop fertilizing after flowering.

6. After flowering

• Leave the leaves until they naturally turn yellow. They replenish the corm for next year’s flowers.
• Once the foliage has died back, stop watering.
• In areas with heavy rain or severe frost, lift the corms, dry them for a few days, and store them in a cool, dry place until the next planting season.

7. Pests and problems

• Rot: Usually caused by overwatering or poorly drained soil.
• Snails and slugs: May eat young shoots.
• Aphids: Can occasionally attack flower stems.
