Sunflower Temperature request: Sunflower is a relatively drought-resistant plant due to its strong and deep root system. As an annual and summer plant, it is grown in subtropical and temperate climatic zones (where the average temperature in July does not fall below 18-19 oC). The total temperature requirement during the vegetation period (80-130 days) is 2600-2850oC. During the germination period, 4-5 oC is required as a minimum, while for a proper emergence, a temperature of at least 8-10oC and optimally 12-14oC is required. Temperatures above 30oC during the development period inhibit growth, and above 40oC pollen is generally unable to germinate and fertilization is either weak or absent. It is not very sensitive to late spring frosts. Young plants are resistant to frost. Seedlings can survive in the cotyledon stage at -5oC. It grows better in sunny, warm places with an average monthly temperature of 25oC during the growing period.

Sunflower Water and soil requirements: Sunflower can use 3 m deep water with its developed root system. Sunflower plant consumes 200 kg of water on average during the development period. Although it is highly tolerant to drought, if drought persists for a long time, the tables remain small, the seed set is low and the yield decreases significantly. As a light and sun-loving species, sunflower needs sufficient light and does not like shade. Sunflower is a plant that can grow in a wide range from heavy clay soils to light sandy soils, from slightly acidic soils to alkaline soils, except very heavy and sandy soils. It can grow best in soils rich in organic matter, humus, alluvial, deep profile and good water retention capacity. The ideal soil pH for its development is 6-7. Sunflower is more salt tolerant than sorghum, soybean, paddy, maize, maize, broad bean, flax and bean and can grow in soils with total soluble salts between 0.640-0.384%.

Can you grow State of Alabama sunflowers

Sunflowers (Helianthus annuus) are generally adaptable plants that can be grown in a variety of climates, including Alabama. Alabama has a warm climate, and sunflowers tend to thrive in full sun with well-drained soil. Here are some general guidelines for growing sunflowers in Alabama or similar climates:

  1. Planting Time:
    • Sunflowers are warm-season plants. Plant them after the last frost date in spring when the soil has warmed up.
    • In Alabama, this is typically in late April to early May, but it may vary depending on the specific location within the state.
  2. Soil Preparation:
    • Sunflowers prefer well-drained soil. Work the soil to a depth of about 2 feet, incorporating organic matter if needed.
    • A slightly acidic to neutral pH (around 6.0 to 7.5) is generally suitable for sunflowers.
  3. Sunlight:
    • Sunflowers thrive in full sunlight. Choose a location that receives at least 6 to 8 hours of direct sunlight per day.
  4. Planting Depth and Spacing:
    • Plant sunflower seeds about 1 to 1.5 inches deep.
    • Space the seeds according to the variety; typically, they should be spaced about 6 to 24 inches apart, depending on the size of the sunflower variety.
  5. Watering:
    • Keep the soil consistently moist until the seedlings are established. Once established, sunflowers are somewhat drought-tolerant, but they still benefit from regular watering.
  6. Fertilizing:
    • Sunflowers generally don’t require a lot of fertilizer. Too much nitrogen can lead to excessive foliage growth at the expense of flowers. A balanced, all-purpose fertilizer can be applied before planting.
  7. Support:
    • Taller varieties of sunflowers may require support as they grow. Stake or provide other support for the plants if needed.
  8. Pest and Disease Management:
    • Keep an eye out for common pests like aphids and caterpillars. Treat as necessary with organic or chemical methods.
    • Ensure good air circulation to reduce the risk of fungal diseases.
  9. Harvesting:
    • Harvest sunflowers when the petals begin to dry and fall off, and the seeds in the center have developed. Cut the flower heads and allow them to finish drying in a well-ventilated area.

Always check the specific requirements of the sunflower variety you choose, as different varieties may have slightly different growing conditions. Additionally, local climate variations within Alabama may influence the success of sunflower cultivation in specific regions of the state.
