How Much Does It Cost To Grow Sunflower Seeds?

Sunflowers grow best at temperatures between 64 and 91ºF (18–33ºC), but can be planted at slightly lower temperatures once the last frost has passed. They usually take 80 to 120 days to mature and produce new seeds, depending on the variety. To ensure successful planting, sunflower seeds should be planted at least ½ inch down into the ground and covered with garden soil.

Sunflowers take 11-18 weeks to flower from seed, so it’s advisable to sow sunflower seeds every couple of weeks for a constant supply of cheerful blooms throughout summer.

For planting giants, 2 ½ to 3 feet (0.75-1 m.) between each plant is necessary for optimum growth. Regular size plants require 1 ½ to 2 feet (0.25-0.50 m.) and miniatures only 6 inches to a foot (15-31 cm).

Should I soak sunflower seeds before planting?

Soaking seeds before planting is a common method to improve germination, as seeds have a hard outer layer to protect themselves from insects and diseases. Soaking them in water softens the hard seed coat, exposing the embryo to moisture and promoting growth. Sunflower seeds don’t need to be soaked, but soaking them for 12 to 24 hours can hasten germination and increase the number of sprouts. To grow sunflowers outdoors, cover the planting area with finished compost or aged manure, then work it into the ground, loosening the top 12-18 inches of soil.

The sunflower crop typically has a seed rate of 40-80 thousand seeds per hectare (16, 2-32, 4 thousand seeds per acre). Agricultural consulting services are available for various sectors, including agriculture, aquaculture, natural resources, environment, safe energy, and home construction. The density of plant standing is determined by calculating the number of plants in a regular row on a plot 14, 28 m long. Field germination is 20-25 lower than laboratory germination, and approximately 5-15 plants die during seedling harrowing and interrow cultivation.

How long does it take to fully grow a sunflower from seed?

Sunflowers bloom from summer to autumn, taking 11-18 weeks to flower from seed. They are easy to grow from seed and ideal for children.
