How To Sow, Grow, And Gather Sunflowers For Bouquets?

Sunflowers are a versatile and easy-to-grow plant that can be used for cutting flowers, making them perfect for beginners. They require full sun, average to good garden soil, and should be sown directly into the soil after all danger of frost has passed. For branching sunflowers, they can be given up to 2 sq. ft. each.

To harvest sunflowers, cut stems just above a node and far enough down the stem to allow nice long stems to grow. Harvest cut sunflowers early in the morning, after any dew has dried but before the temperature warms and the sunflower plant’s transpiration rate increases. Use high-quality bypass pruners when harvesting.

Sunflowers are hardy and perfect for beginning growers, making them ideal for making bouquets and keeping them in bloom all season. To harvest flowers, cut the main stem just before its flower bud has a chance to open to encourage side blooms. There are several ways to harvest sunflowers, including cutting heads off the plant, leaving a short length of stem attached to the flower, and collecting seeds with as little loss as possible.

For single stem sunflowers, plants should be spaced 4-9″ apart, with 6″ spacing being the recommended spacing. Cutting sunflowers are easy to grow, and they can be started early in cells or pots, but it’s best to sow directly into your garden bed. Harvest cut sunflowers early in the morning, after any dew has dried but before the temperature warms and the sunflower plant’s transpiration rate increases.

When to harvest sunflowers?

After the sunflowers have died back completely and the backs of the blooms are brown, it’s time to harvest the seeds. Cut the stalk with sharp scissors or pruners and place them in a container to catch loose seeds. De-seed the sunflower blooms, either wearing gloves or not, and rub the seed head over a bucket to catch the seeds. You may also get petals and other sunflower matter in with the seeds, which will be removed later.

If you plan to re-plant the seeds or make suet cakes, rinse them in a colander and remove any non-seeding bits and pieces. Line a shallow cardboard box or wooden crate with newspaper and paper towels and scatter the seeds in a single layer to dry, leaving space between each seed. Allow the seeds to dry for several hours or overnight. If you’re saving seeds for re-planting, store them in an airtight container in a cool, dry place until ready to plant.

How to grow a cut sunflower?

Sunflowers are annual plants native to North America known for their bright blooms and large petals. They are heliotropic, meaning young flowers grow with their face to the sun, returning an easterly position at night. Mature sunflowers grow to nearly 10 feet tall with minimal maintenance requirements. They are a pseudanthium, or flowerhead, made up of many small flowers. The outer petals are called ray flowers, while the black-brown flowers in the center, called disk flowers, grow in a spiral formation and mature into sunflower seeds when pollinated by bees.

Sunflowers are low-maintenance and drought-tolerant, growing in most soil conditions. To propagate them, choose a four-to-six-inch stem with mature leaves and no flower buds. Remove all but two or three leaves, expose the nodes, and dip cuttings into a rooting hormone if desired. Plant the leafless section of the cutting in a potting mixture filled with half sand and half peat moss.
