Growing Zinnia California Giants

Indoor Sowing: Not Recommended.

Direct Sowing: Spring.

• It is best to grow zinnia from seed, as they do not like to be transplanted. From seed, they will grow very quickly in the right conditions.
• Do not seed until the last frost has passed.
• Choosing a location that gets full sun is essential.
• Zinnias are adaptable, but the ideal soil is nice and fertile, humus-rich, and well-drained.
• Soil pH should be between 5.5 and 7.5. If soil is amended with compost, the flowers will grow more quickly.
• Sow Zinnia Seeds seeds only ¼-inch deep.
• Germination takes about 4 to 7 days.
• When seedlings reach three inches tall, thin them so that they’re 6 to 18 inches apart to maximize air circulation.
• Sow in succession for a longer flowering display.
