Mexican Sunflower Mix

120 Seeds

Mexican Sunflower Mix is a fast-growing annual flower that produces large, bright orange, yellow, and reddish-orange daisy-like blooms on tall plants reaching 1.5–2 meters. It is excellent for flower borders, privacy screens, cut flowers, and pollinator gardens, attracting bees and butterflies. In the Gulf region, it grows best during the cooler season and can tolerate heat once established.

Best Planting Time

• September to February (recommended)
• Can also be sown in early March in cooler Gulf areas.
• Avoid sowing during the extreme summer heat.

Seed Preparation

• No soaking is usually required.
• Optional: Soak seeds in lukewarm water for 4–6 hours before sowing to encourage faster germination.
• Use fresh, high-quality seeds.

Soil Preparation

Mexican Sunflower prefers light, fertile, well-drained soil and can tolerate average garden soil.

Recommended mix:

• 40% Sandy garden soil
• 30% Compost
• 20% Coco peat
• 10% Perlite

Ideal soil pH:

• 6.0–7.5

Sowing Method

• Sow seeds directly in the garden or in large seed trays.
• Plant seeds 1–2 cm deep.
• Cover lightly with soil.
• Keep soil slightly moist until germination.
• Transplant carefully when seedlings have 3–4 true leaves.

Temperature & Light

• Ideal germination temperature: 20–25°C
• Ideal growing temperature: 20–32°C
• Requires 6–8 hours of direct sunlight daily.
• Full sun encourages stronger stems and more flowers.

Watering

• Keep soil evenly moist during germination.
• Once established, water deeply when the top 3–5 cm of soil becomes dry.
• Mexican Sunflower is moderately drought tolerant after establishment.
• Avoid excessive watering.

Germination Time

• 7–14 days

Plant Spacing

• 60–90 cm between plants.
• 90–120 cm between rows.

Flowering

• Flowers begin approximately 10–14 weeks after sowing.
• Regular removal of faded flowers encourages more blooms.
• Flowers are excellent for summer-style bouquets.

Fertilization

• Add compost before planting.
• Feed lightly every 4–6 weeks with a balanced fertilizer.
• Avoid excessive nitrogen, which causes tall leafy growth with fewer flowers.
• A fertilizer with slightly higher phosphorus and potassium supports better flowering.

Gulf Climate Tips

• Grow during the cooler season for the best flowering.
• Plant in an open sunny location.
• Provide support in windy areas because plants can become tall.
• Apply mulch to reduce moisture loss and protect roots.
• Water early in the morning.
• Monitor for aphids, spider mites, caterpillars, powdery mildew, and leaf spots.
• Mexican Sunflower Mix performs beautifully in large garden beds, borders, fences, landscape areas, and pollinator gardens throughout the Gulf.
