Why Grow Sunflower Plants?

What type of sunflower do you want to grow? Is it a single tall plant or multiheaded constant flowering sunflower which is great as cut-flowers. Suttons have many sunflower varieties for you to pick from, ‘Giant Yellow’ is exactly as its name with bright yellow blooms. ‘Ruby sunset’ is multiheaded with rustic deep red flowers. 

‘Wahoo’ is a classic looking but low growing multi-headed flowering Sunflower which is great for containers. For something a little bit different sow dwarf sunflower seeds, and grow red Sunflowers with ‘Ms mars’ choose from our sunflower range today and get growing.

How To Grow Sunflower Seeds?

Your Sunflower seeds need to be sown under glass between March and April or outdoors between April and June for flowers between July and September.

  • Sunflowers are hardy annuals and are fine being sown where they will be grown. Sow seed thickly onto well-prepared ground that has had some good well-rotted manure forked in
  • Remove excess sunflower seedlings to correct spacing, remember to label. Alternatively, Sunflowers can be started in a Suttons cell propagator kit
  • Good rich soil is important and as they are sunny by name and sunny by nature give them a nice hot spot.
  • Sunflowers are phototrophic which means their flower heads turn with the sun as it crosses the horizon. They will enjoy a foliar feed, starting with Seaweed and followed by Potash. Keep watered Sunflowers as they grow
  • Stake taller giant varieties to stop them getting wind damage, plant supports or a nice long bamboo cane will suffice, use soft garden twine tied in a figure of eight to prevent rubbing of the plant’s stem
  • Beware of slugs in the early days of a sunflowers life, set traps or protect with organic slug pellets. If you see any slugs and snails in the area remove them as far away as you can

Once the Sunflower heads go over why not give the small birds treat, leave them on the plant as our feathered friends will love eating the seed.

How long does it take for Sunflower seeds to germinate?

Sunflower seeds should germinate within 7 to 21 days. As the seedlings grow thin in stages to achieve final spacing of 30 to 45cm. Make sure all plants are supported as they grow.

Sunflowers are easy to grow, so why not try growing the ultimate Sunflower, choose a variety like giant yellow sunflower and plant it in a south-facing aspect, preferably about 45 cm from a brick wall. Water regularly. As soon as the Sunflower starts to get growing, feed it with Seaweed extract diluted in water every couple of weeks. An Organic mulch spread thinly around will help.

Place a good strong Bamboo cane alongside your Sunflower and tie in. Switch the foliar feed to Tomato feed when the flowers begin to appear. Make sure it’s measured when it reaches full size!
