Growing Instructions from Seeds

Zinnia can be direct sown or started in seedling trays.

Sow seeds approximately:

0.5–1 cm deep

Keep the growing medium lightly and consistently moist until germination.

If raised in trays, transplant seedlings carefully while young.

Germination

5–10 days

For best results:

• Maintain 20–30°C

• Keep soil lightly moist

• Provide good drainage

• Avoid overwatering

• Provide strong light after germination

Plant Spacing

Maintain approximately:

30–40 cm / 12–16 inches between plants

to allow sufficient room for tall growth and branching.

Sunlight

Provide:

Full sun — preferably 6–8 hours or more of direct sunlight daily.

Watering

Water regularly while plants establish.

Once established, water deeply when the upper soil layer begins to dry.

Avoid continuous wet foliage and waterlogging.

Growth & Flowering

Zinnia California Giant Mix develops a tall, upright and branching growth habit with multiple large blooms.

The mix may produce flowers in shades of red, pink, rose, orange, yellow, purple, white and related tones.

Regular cutting and deadheading encourages continued flowering.

Feeding

Moderate feeding during active growth supports strong stems and abundant flowering.
