When to sow Nasturtium Seeds 

Nasturtium seeds can be sown indoors in spring or sown directly outdoors from late spring once the soil has warmed. As they are fast-growing annuals, they quickly establish and provide colourful displays throughout summer. 

How to grow Nasturtiums from seed 

Nasturtium seeds are large and easy to handle, making them ideal for beginner gardeners. Sow seeds around 2cm deep in moist, well-drained soil and keep them watered while they establish. Nasturtiums grow best in a sunny position, although they will tolerate light shade. Avoid overly rich soils, as these can encourage leafy growth at the expense of flowers. 

How long does it take for Nasturtiums to flower? 

Nasturtiums are quick to grow and typically begin flowering within a few weeks of sowing. They continue producing blooms throughout summer and into autumn, often until the first frosts. 

Why grow Nasturtiums from seed? 

Growing nasturtiums from seed is an inexpensive and rewarding way to add vibrant colour to the garden. Their flowers attract bees and other pollinators, while both the flowers and leaves are edible and can be used to add colour and a peppery flavour to salads. Nasturtiums are also valued as companion plants in vegetable gardens. 

Where can you grow Nasturtiums? 

Nasturtiums are extremely versatile and can be grown in borders, raised beds, containers, hanging baskets and vegetable plots. Trailing varieties are perfect for spilling over the edges of pots and baskets, while bush varieties are ideal for bedding displays and edging paths. 

Which Nasturtium variety should I choose? 

The best nasturtium variety depends on where you plan to grow it. Compact bush varieties are great for containers and smaller gardens, while trailing varieties create eye-catching displays in hanging baskets, window boxes and along raised beds. Flowers are available in shades of yellow, orange, red and cream, with many varieties featuring attractive contrasting foliage.
