Full details
Nasturtium 'Whirlybird Mixed' is an ideal choice for gardeners looking for low-maintenance, high-impact color in beds, borders, or patio containers. These plants produce vibrant, semi-double blooms nestled within low mounds of foliage, providing a fiery aesthetic throughout the summer months. While they are incredibly versatile and easy to grow, they are sensitive to frost and require a sunny location to reach their full flowering potential.

FAQs
When is the best time to sow Nasturtium seeds?
Sow outdoors once the risk of frost has passed to ensure the soil has warmed up sufficiently for germination.
Can I grow these in pots?
Yes, they are excellent for containers provided you use free-draining compost and ensure the plants are well-rooted before transplanting.
How deep should I sow the seeds?
Sow seeds 20mm deep for outdoor beds, or 1cm deep if starting in pots indoors.
Do I need to fertilize them frequently?
Nasturtiums generally require little attention once established and typically perform well in standard garden soil without heavy feeding.
How much space does each plant need?
Each plant grows up to 35cm in spread, so space them accordingly to allow for adequate airflow and growth.
Troubleshooting
Seeds failing to germinate
Ensure soil temperatures are within the 20-29C range if starting indoors, or wait for the soil to warm up if sowing outdoors.
Plant looks leggy with few flowers
The plant is likely not receiving enough sunlight; move the container or choose a sunnier location in the garden.
Wilting foliage
Check the soil moisture; while they are hardy, they require regular watering until the root system is fully established.

Setup, Compatibility & Care
To achieve the best results, sow seeds 20mm deep in rows spaced 30cm apart. If you prefer earlier flowering, you can start seeds indoors at 20-29C in free-draining, damp compost. Whether starting indoors or outdoors, always remember to harden off your plants by gradually exposing them to outdoor conditions before transplanting. Once planted out, maintain a regular watering schedule until the plants are fully established. The plants require full sun for optimal bloom production. Avoid frost, as it will damage or kill the plants.
