As a seasoned gardener based in Staffordshire, I often get asked about the best ways to grow nasturtiums, especially in pots and containers. These vibrant flowers are not only a delight to the eyes but also incredibly versatile and easy to grow, making them perfect for any garden space, big or small. Whether you're a novice or an experienced gardener, growing nasturtiums in containers can be a rewarding experience.
Quick Answer
Nasturtiums thrive in pots with well-draining soil, regular watering, and partial sunlight. They're ideal for UK climates, adding colour from late spring to autumn.
Why Choose Nasturtiums?
Nasturtiums are a favourite among UK gardeners due to their vibrant colours and ease of care. They not only provide a splash of colour but also attract beneficial insects like bees and butterflies to your garden. Moreover, both the flowers and leaves are edible, adding a peppery flavour to salads.

Choosing the Right Container
When it comes to growing nasturtiums in containers, size matters. Choose a pot that's at least 30 cm in diameter to give the plant's roots plenty of room to spread. Ensure the pot has drainage holes to prevent waterlogging, which can be particularly problematic in the rainy Midlands climate.
Container Materials
While any material can work, consider using terracotta pots as they provide good drainage and stability. Additionally, they help regulate soil temperature, which is beneficial in our sometimes unpredictable UK weather.
Soil and Planting
Nasturtiums aren't too fussy about soil, but they do prefer a well-draining mix. A standard potting compost mixed with a bit of sand or grit will do wonders. Avoid overly rich soil, as this can lead to more leaves and fewer flowers.
| Month | Action | Details |
|---|---|---|
| March | Sow Seeds | Indoors in a greenhouse |
| May | Transplant | Move seedlings to outdoor pots |
| June to September | Enjoy Blooms | Water regularly and deadhead spent flowers |
Watering and Care
Regular watering is key, especially during dry spells. However, be careful not to overwater, as nasturtiums prefer to be on the drier side. In Staffordshire, where we get a fair amount of rain, you might find that natural rainfall is often sufficient.
Fertilising
Nasturtiums don't require much fertiliser. In fact, too much can lead to lush foliage but fewer flowers. A light application of a general-purpose fertiliser once a month should be more than enough.
Common Issues
Nasturtiums are generally hardy, but watch out for aphids. These pests can be controlled by encouraging their natural predators or by using a soapy water spray. Another thing to note is that nasturtiums can suffer from mildew if air circulation is poor, so ensure your pots aren't crowded together.
Frequently Asked Questions
Can nasturtiums grow indoors?
Yes, they can, but they prefer being outdoors where they can enjoy the sunlight and fresh air.
Do nasturtiums need full sun?
They thrive in full sun but can tolerate partial shade. In the Midlands, a south-facing spot is ideal.
How do I harvest nasturtium seeds?
Wait for the seeds to dry on the plant, then collect them before they fall to the ground. Store in a cool, dry place for next year.
