Sunflowers are one of the heartier, easier to grow flowers for a garden.
They can be grown in a container and then transplanted, but most people find it easier to grow them directly in their garden.
It’s best to plant them in the spring after the last frost.
What month do you plant sunflowers?
Plant the large seeds no more than 1 inch deep about 6 inches apart after the soil has thoroughly warmed, from mid-April to late May in northern regions—earlier in southern areas. You can plant multiple seeds and thin them to the strongest contenders when the plants are six inches tall.
What is the best way to grow sunflowers?
Sunflowers grow best in full, bright sun, and in evenly moist, well-drained soil. The amount of space they need depends on which varieties you are growing. Branching types with multiple blooms on one stem need more space horizontally than large single-flowered types.
How close together can you plant sunflowers?
Space seeds about 6 inches apart in a shallow trench between 1 and 2 inches deep. In sandy soil, 2 inches deep is better. Cover and keep watered until seeds sprout in 7 to 10 days. When first true leaves appear (the second set of leaves); thin plants to about 2 feet apart.
Do sunflowers come back every year?
While most varieties of this bright beauty are annual sunflowers, meaning they will not come back the following growing season, they may self-germinate from dropped seeds if you leave the heads on the plants throughout the winter. The perennial Maximillian sunflower features small blooms in late summer and early fall.
