Sunflowers are the cheerful stars of any garden! These sunny blooms are easy to grow, love the heat, and attract friendly pollinators. If you want to add a splash of color to your yard, here’s how and when to grow plant sunflowers.
What Are Sunflowers?
Sunflowers, known scientifically as Helianthus annuus, are annual plants famous for their big, daisy-like flowers. The name comes from Greek, meaning “sun flower.” Although yellow with brown centers is common, they can also be red, orange, maroon, or brown. These flowers not only look great but also feed bees, birds, and butterflies!
Sunflowers have a cool trick called heliotropism. When they’re young, they turn to follow the sun across the sky during the day and face east again at night.
How Long Until They Bloom?
Most sunflowers grow pretty quickly, taking about 70 to 95 days to bloom. Some can reach over 16 feet tall, while others are small enough for pots, usually around 1 foot tall. The larger flowers can have heads over 12 inches wide!
Planting Sunflowers
1. Find the Perfect Spot
- Sunshine: Sunflowers love direct sunlight, so pick a spot that gets 6 to 8 hours of sun each day.
- Wind Protection: To keep tall sunflowers from falling over, plant them near a fence or building.
- Soil Quality: They need well-draining soil that doesn’t hold water. Sunflowers prefer slightly acidic to neutral soil (pH 6.0 to 7.5) and need lots of nutrients, so add compost or fertilizer.
2. When to Plant
- Timing: Plant seeds after the last frost when the soil is at least 50°F (10°C). This is typically between April and mid-June in the northern U.S. and as early as mid-March in the South.
3. Planting the Seeds
- Depth and Spacing: Plant seeds 1 to 1.5 inches deep and about 6 inches apart. You can plant more seeds and thin them later for a fuller display.
- Row Spacing: Keep rows 30 inches apart for larger varieties.
- Fertilization: Adding a little fertilizer when you plant can help roots grow strong.
Caring for Sunflowers
1. Watering and Maintenance
- Initial Care: Water around the roots, but keep it 3 to 4 inches away from the plant.
- Established Plants: Once they’re growing well, water deeply once a week unless the weather is extreme.
- Fertilization: Be careful with fertilizer; too much can weaken the stems. If you do use it, apply it gently around the base of the plant.
2. Supporting Tall Varieties
For taller sunflowers, use bamboo stakes to help keep them standing strong.
Harvesting Sunflowers
1. Cutting for Bouquets
- Cut the flowers just before they open for indoor arrangements.
- Harvest in the morning, remove all leaves except for the ones near the flower head, and cut the stems at a 45-degree angle.
2. Harvesting Seeds
- Let the flower dry until the back turns brown and the seeds look plump.
- Cut off the head about 6 inches below the flower and put it in a container.
- Remove seeds by rubbing them out with your hand or a fork.
- If you want to roast the seeds, cover the flower head to keep birds away and hang it upside down until dry.
3. Storing Seeds
Keep seeds in an airtight container in a cool, dry spot until you’re ready to plant again.
4. Dealing with Pests and Diseases
Sunflowers are tough but might attract birds and squirrels. To keep them safe:
- Use barriers to keep critters away.
- If you notice any diseases like mildew, use a garden fungicide early on.
Conclusion
Growing sunflowers is a fun and rewarding activity! Whether you want a beautiful garden or tasty seeds for snacks, these flowers are a great choice. So grab some seeds, find a sunny spot, and let the sunflowers brighten up your garden!
