Garden Displays and Cut Flowers
Plant Lemon Striker in groups through sunny borders or dedicate a section of the garden to flowers for cutting. Leave enough space around each plant for its side branches to develop.
Cut selected stems as the petals begin to open and place them promptly in clean water. Remove leaves that would sit below the waterline and keep arrangements away from direct heat.
How to Grow Lemon Striker Sunflowers
- Choose a growing position. Select a sunny site with well-drained soil and some protection from strong winds.
- Prepare the soil. Loosen the planting area and incorporate mature compost where needed. Use quality potting mix for containers.
- Sow the seeds. Plant approximately 1 cm deep and water gently. Direct sowing avoids disturbing developing roots.
- Maintain moisture. Keep the seedbed moist without waterlogging it until seedlings establish.
- Allow room to branch. Thin seedlings to approximately 30 cm apart. If raising seedlings in pots, transplant while young with minimal root disturbance.
- Water and support as needed. Water thoroughly when the soil begins to dry. Provide stakes in exposed positions and feed container plants according to the fertiliser label.
- Enjoy the flowers. Leave blooms for garden colour or cut selected stems for arrangements. Remove faded flowers carefully, preserving developing side buds.
