Instructions
Sunflowers do not transplant well and it is best if seeds are sown directly into the garden when the soil is warm and all danger of frost is passed. Soil temperature (not air temperature) should be warmer than 10°C (50°F) for seeds to germinate Planting at a lower temperature will delay germination. Choose a location that receives at least 6 hours of sunlight daily. Space seeds and plant to the depth indicated below. Press seeds into the soil to ensure good contact and cover with 3 mm (1/8 in.) of soil. After planting, water the seeds with a gentle mist or shower. A hard spray can wash soil away, dislodge seeds and clump them together. It is critical to keep the soil consistently moist, but not soggy during germination. Do not let the soil dry out, as young plants have underdeveloped roots and can quickly dehydrate, particularly in windy conditions. When your seedlings reach a height of a few centimetres (inches) and have developed 2 or 3 pairs of leaves, it is important to thin them out, according to the plant spacing indicated below to provide good air circulation and room to grow.
- Planting Depth: 1.3 cm (1/2in.)
- Seed Spacing: 8 cm (3 in.)
- Plant Spacing: 45 cm (18 in.)
- Instructions for Nutrient Care: Apply SUPERThrive once per week. Soak in solution of 1/4 tsp per gal for 15 min. or longer depending on size and type.
Suggestions
Growing Suggestions:
- If birds are scratching around for the seeds, cover the planted area with netting until the seeds germinate.
- Tall varieties should be grown in a sheltered location so they are protected from the wind. Larger varieties can become top-heavy, and a strong wind can topple them.
- Sunflower seeds can be succession planted every 2 to 3 weeks until mid-July for continuous flowers until frost.
- Once plants are established, it's important to water the new plants thoroughly but not too frequently. This will encourage the roots to grow deeply into the soil.
- Harvest flowers when they have just opened.
- Harvest seeds in late summer and fall for snacking or to feed the birds.
