Growing Tips, Tricks and FAQs
Growing Tips
The Mexican Arcadian Blend sunflower thrives best in full sun, requiring at least 6 hours of direct sunlight daily. The soil should be light, well-draining, and moderately fertile. Excessively nitrogen-rich soil will adversely affect blooming. Water regularly but avoid waterlogging. Applying mulch around the base helps to retain moisture and suppress weeds. Given their height, plants may need staking in windy areas to prevent damage.
When to Grow
Plant your sunflowers in late spring, after all chance of frost has passed and the soil has warmed to at least 50 F. It's important to wait until all risk of frost is gone because sunflowers are highly frost-sensitive. If you’re unsure about your frost dates, consult your USDA growing zone for specific timing in your region.
How to Sow and Plant
Sow seeds directly outdoors, as sunflowers dislike transplanting due to their long taproots. Plant seeds about 1/2 inch deep. Once seedlings are a few inches tall, thin them out to about 18-24 inches apart to provide enough space for each plant to grow. Keep the soil moist during germination but not soggy.
How to Grow
Mexican Arcadian Blend sunflowers require full sun and regular deep watering to promote strong root systems. Fertilize lightly to enhance growth, but be careful not to over-fertilize, which can lead to weaker stems. Support taller plants with stakes, especially in windy locations. These sunflowers bloom from summer into early fall and attract pollinators like bees and butterflies.
How to Save
- When petals die back and heads begin to dry and turn brown, place a paper bag over the heads to protect seeds from birds.
- After a few days, the heads will dry to a dark brown. Bring the heads indoors and hang them upside down in a dry area in direct sunlight for up to a week, shaking seeds free each day.
- Store in a cool, dark, dry place.
