Sunflowers are a simple way to add cheer to any garden! These bright, tall flowers are easy to grow, thrive in warm weather, and attract pollinators like bees and butterflies. Here’s a simple guide on when and how to plant sunflowers.
What Are Sunflowers?
Sunflowers, or Helianthus annuus, are annual plants known for their large, sunny flowers. While yellow with brown centers is the most common, they also come in shades of red, orange, maroon, and brown. These flowers aren’t just pretty—they’re great for feeding bees and birds!
A cool fact about sunflowers is their heliotropism; young sunflowers turn to face the sun during the day and reset to face east each night.
How Long Until They Bloom?
Sunflowers grow fast, usually taking 70 to 95 days to bloom. Some varieties can get over 16 feet tall, while others are smaller, ideal for growing in pots. The bigger flowers can have heads over a foot wide!
Plant Sunflowers
Choosing the Right Spot
- Sunlight: Sunflowers love the sun, so find a spot that gets 6 to 8 hours of sunlight daily.
- Wind Protection: To protect tall sunflowers from strong winds, plant them near a fence or a wall.
- Soil: Use well-draining soil that doesn’t stay soggy. Sunflowers like soil that’s slightly acidic to neutral (pH 6.0 to 7.5). Adding compost can help provide nutrients.
Best Time Plant Sunflowers
- Timing: Plant seeds after the last frost when soil temperatures reach 50°F (10°C). This is usually from April to mid-June in cooler climates, and as early as mid-March in warmer areas.
Plant Sunflowers Instructions
- Depth and Spacing: Sow seeds 1 to 1.5 inches deep and space them 6 inches apart. Plant a few more than you need, and thin them out later.
- Row Spacing: Keep rows about 30 inches apart if you’re growing larger varieties.
- Fertilizer: A bit of fertilizer when planting can help with strong root growth.
Taking Care of Sunflowers
Watering Tips
- Early Care: Water around the base of the plant, but keep the soil a few inches away from the stem dry.
- Once Established: Water deeply once a week, unless it’s extremely hot.
- Fertilizer Caution: Use fertilizer sparingly, as too much can make stems weak. If needed, apply it gently around the base.
Support for Taller Varieties
Use bamboo sticks or stakes to support taller sunflowers, keeping them upright.
Harvesting Sunflowers
For Bouquets
- Cut flowers just before they open for arrangements. Harvest in the morning, remove excess leaves, and cut stems at a slant.
For Seeds
- Let the flowers dry on the plant until the back turns brown. Then, cut the heads and store them in a container. Rub the seeds out with your hand or a fork. If you want to roast them, cover the drying heads with netting to protect from birds.
Storing Seeds
Keep seeds in a cool, dry place in an airtight container until next plant sunflowers season.
Handling Pests and Diseases
Sunflowers are hardy but can attract birds, squirrels, or pests. To protect them:
- Use barriers to keep critters away.
- For diseases like mildew, apply a garden-safe fungicide early on.
Summary
Growing sunflowers is easy and fun! Whether you’re aiming for a colorful garden or want a supply of tasty seeds, these plants are a fantastic choice. Just find a sunny spot, sow some seeds, and enjoy the bloom!
