More details about Short Blend Sunflowers

Helianthus annuus. This selection of our loveliest short-growing sunflower seeds brings a mix of variety and spontaneity to the sunflower patch. Ideal for small city gardeners, they can also be grown in containers. The Short Blend Sunflowers contain a variety of field grown sunflowers ranging from 60-120cm (24-48") tall. Plant and enjoy all these lovely, height-challenged sunflowers. Even when they're small, sunflowers are extremely attractive to pollinators, so they are perfect for the edge of the organic vegetable garden, and will bring in scores of honeybees and other beneficial insects. Though their tiny seeds are, in theory, edible, they make better food for the wild birds that will frequent the garden in late summer.

Timing

Timing
Direct sow repeatedly after the last frost date. Starting indoors is possible, but does not gain much time. If sunflowers are allowed to get root-bound, they will lack stability at transplant time, and will require staking. Optimal soil temperature for germination: 21-30°C (70-85°F). Seeds should sprout in 10-14 days.

Starting

Starting
Sow seeds 5mm-1cm  (¼-½”) deep. Space dwarf varieties 15cm (6″) apart, but give the giants lots of room at 1m (3′) between plants.

Growing

Growing
To grow really big plants with really big flowers, enrich the soil with organic matter and incorporate 2 cups of balanced organic fertilizer per 3m (10′) of row, and irrigate regularly. When the plants are 30cm (12) tall, dissolve 5ml (1 tsp) of borax (for boron) in 350 ml (12 fl oz) of water and spread the solution over 5m (15′) of row. Be careful not to over-apply this solution. This application of boron will produce bigger seeds and flower heads. Do not apply boron to other garden plants. When the back of the flower head turns yellow, it is ready to be cut from the plant.

Companion Planting

Companion Planting
Sunflowers planted near rows of corn are said to increase yields. Sunflowers can be used to draw heavy metals, toxins, and even radiation from soil, but should be burned at the end of the season if grown for this purpose. Plant sunflowers amid squash plantings to improve pollination and overall production.
