Nasturtiums must have sun for at least half the day in order to grow well and do best in sites sheltered from winds. A free-draining soil is essential, and nasturtiums flower best in poor soils (that are low in fertility) as a fertile soil results in lots of leafy growth at the expense of flowers. Hence there’s no need to add fertilizer before sowing. Nasturtiums do well in gravelly or stony ground or growing on banks. In containers, mix two-thirds peat-free multi-purpose compost with one third fine gravel or grit, to reduce fertility and ensure good drainage.
For best results, sow nasturtium directly where they are to flower, as they’re fast-growing and there’s no need to bother about transplanting. Sow the seed 1.5 cm deep into moist soil to speed germination, so water before planting if conditions are dry. The first seeds can be sown in mid-spring and you can carry on sowing until mid-summer to ensure flowers right up to the first frosts. Thin the seedlings to 30 cm apart. However, sowing in pots also works – simply sow one seed per pot and transplant outside when all risk of frost has passed.
