SOWING: Direct seed (recommended) - After last frost, sow ½" deep. Transplant - Sow into 72 to 50-cell flats 2-3 weeks prior to planting out. Plants dislike root disturbance but sowing indoors and then transplanting the first crop outdoors can be a successful way to get first-early sunflowers. Pinching branching varieties is recommended to encourage branching and longer stems. Succession-sow every 2-3 weeks and/or plant multiple varieties for continued harvest.
LIGHT PREFERENCE: Sun.
PLANT HEIGHT: Varies.
PLANT SPACING: 18-24".
HARDINESS ZONES: Annual.
HARVEST: Flowers can be harvested tight, when color first shows, or when almost completely open, depending on your market and preferred use. Dried - Flowers are completely open. Hang or use silica gel.
SOIL REQUIREMENTS: Light, well-drained soil. Excessive nitrogen may cause plants to grow too vigorously with abnormal flower shapes.
USES: Excellent cut flower. Single stem sunflowers can make a beautiful and reliable display in the garden but please note that they will only provide one bloom form each plant.
NOTES: Flower size and stem diameter are controlled by plant spacing, temperature, soil type, and day length. For early and late season production, select varieties that are day-length neutral or are noted as suitable for flowering under short days.
