Sunflowers are not particularly fond of being transplanted, but if started indoors, sow in peat pots, 6 to 8 weeks prior to the last frost. Sow at a depth of 1/2” under topsoil. Transplant entire pots into the garden, or direct sow when the weather is warm and all danger of frost has passed. Stakes may be necessary to support your Sunflowers, only until the stems become stronger enough to stand on their own.
Sunflowers grow long taproots and may rot if the roots become waterlogged. It is recommended to check your sowing area for hard, compacted soil prior to sowing. Renew any hard, compacted soil with a mixture of compost. Sunflowers will enjoy an area of full sunlight for the majority of the day and should be watered daily so that the soil is kept moist until germination has occurred.
Your sunflower seeds will begin to germinate within 7 to 10 days after sowing. Plants will grow to a mature height of roughly 5 to 6 feet tall and can be spaced about 12 inches apart from one another. Henry Wilde produces 7 to 10 inch, yellow blooms with dark brown centers. An excellent cut flower for bouquets and floral arrangements.
