Can Newly Cut Sunflowers Be Planted?

This article discusses the process of planting cut sunflowers and the factors that affect their success. Sunflowers are easy to grow from cuttings, especially in the morning after dew has evaporated. After cutting, place the sunflower in a vase with fresh, cool water and check for growth. Keep the cutting in the shade for a few days before moving to full sunlight.

Sunflowers are drought-tolerant, resilient, and brighten up your garden. To propagate, cut the sunflowers from the bottom at a 45-degree angle, which will help grow roots faster. Cut stems should have 6 to 9-inch lengths. When planting, keep the sunflowers fresh and condition them to add boldness and rich color to cut flower arrangements.

Sunflowers are an excellent option for cut flower growers or as part of a cutting garden, especially during shoulder seasons when not much else is in the way. To plant sunflowers, recommend 6″ spacing between single stem sunflowers and 24″ spacing between branching sunflowers. Plant the seed about 1 inch apart.

If you want to grow sunflowers for cutflowers in a small garden, be selective of the varieties you choose. If a cut sunflower won’t root, try drying it and harvesting the seeds before planting. Place the stems immediately in the fresh solution and place the bucket of flowers in a cool location for at least one hour before arranging.

Starting sowing sunflower seeds indoors in March is recommended, but it is best to wait until they are sturdy plants, about 30cm tall, before planting outside.

Do sunflower seeds need to be dried before planting?

To harvest sunflower seeds for re-planting, rinse them and allow them to dry for several hours or overnight. If you plan to save the seeds for re-planting, store them in an airtight container in a cool, dry place until ready to plant. De-seed the sunflower bloom by rubbing the seed head over a bucket, removing petals and other sunflower matter. Rinse the seeds in a colander and remove any non-seeding bits. 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 plan to save the seeds for re-planting, store them in an airtight container with the variety and date of harvest. This method ensures the seeds last for years.

How to keep sunflowers alive after cutting?

Sunflowers require freshwater to maintain their hydration and freshness. They require water immediately after being picked to prevent wilting. Even with flower preservatives, bacteria can grow in stagnant water, and old water can become smelly. To keep them alive, change the water in your vase daily. To keep sunflowers alive, water them two hours before removing them from the garden bed and pick them during the first hours of dawn to absorb the previous night’s cooler water temperatures.

Can you replant fresh cut sunflowers?

When harvesting single stem sunflowers, cut towards the base of the flower while leaving enough stem in the ground for replanting. White Nite varieties have more fragile blooms than ProCut varieties. Harvest sunflowers as soon as petals start to lift from the center disc, as fully open sunflowers may shorten vase life. Use sharp pruners or snips to cut stems, and remove the bottom three-fourths of leaves from the stem and place them in a clean bucket. Avoid removing the stem and leaves from the stem.

Will a cut sunflower stem grow back?

Late summer blooming sunflowers should be pruned back when they reach 1. 5 to 2 feet (0. 5 to 0. 6 m) in height, as they will recover and bloom in a few weeks. Maximililian sunflowers and Mexican sunflowers should be trimmed in June or July to reduce their height from 9 feet (2. 7 m) or greater to a more manageable 4 feet (1. 2 m). Maximililian sunflowers can be left standing for birds during winter months, or cut to the ground in early spring to prepare for new growth.

How do you revive fresh cut sunflowers?

Sunflower stems are thick and require a lot of water, which can cause them to droop due to insufficient water intake. Air can get trapped in the tips of the stems, causing the stem to lose its water tension and droop. To revive drooping sunflowers, cut an inch off each stem at a 45-degree angle and place them back in cold, fresh water. They should perk up within 24 hours. Ensure you have the correct vase, as sunflowers are best displayed in a tall vase.

If you don’t have a tall vase, cut the stems down so the head is 2-3 cm above the rim to support the heads. If your sunflowers don’t perk up after 24 hours, contact us or visit our Flower Care Essentials page.
