FAQs
What makes these sunflowers 'bi-colour'?
The 'Harlequin Mix' features petals that are not a single solid colour. They often display a blend of colours, including unique shades like rose pink, or have contrasting colours on the same petal.
Why are these sunflowers pollen-free?
Certain sunflower varieties are bred to be pollen-free, which makes them ideal for use as cut flowers. This means they won't shed pollen on furniture or tablecloths when used in arrangements.
How tall do the Thompson & Morgan Harlequin Mix sunflowers grow?
When fully established, these sunflowers can reach a height of up to 150cm (approximately 5 feet).
What is the best time to sow these seeds?
You can sow them directly into the garden from March to May. For earlier blooms, you can start them indoors in late winter or early spring.
Do I need to provide support for these sunflowers?
Given their potential height of up to 150cm, it is advisable to provide some form of support, such as staking, especially in windy locations, to prevent the plants from bending or breaking.
Can these sunflowers be grown in pots?
Yes, they can be grown in pots, but ensure the pots are large enough to accommodate the plant's mature size (up to 50cm spread) and have good drainage.
What kind of soil do these sunflowers prefer?
They prefer a well-drained soil. Ensure the soil is not waterlogged, as this can hinder growth and potentially lead to root rot.
Troubleshooting
Seeds not germinating
Ensure seeds are sown at the correct depth (12mm) and temperature (20-30°C for indoor sowing). Check soil moisture; it should be consistently moist but not waterlogged. Germination can take up to 21 days.
Seedlings are weak or leggy
Provide adequate light, especially for indoor-sown seedlings. Ensure they are not overcrowded. Harden off plants gradually before planting outdoors to prevent shock.
Plants not flowering
Confirm plants are receiving full sun (at least 6-8 hours daily). Ensure adequate watering and a well-drained soil. Nutrients in the soil may also play a role; consider a balanced fertilizer if growth is poor.
Pest damage (e.g., slugs, snails)
Protect young seedlings with barriers or slug pellets. Encourage natural predators if possible. Regular inspection can help catch infestations early.
