How to grow Nasturtium Tom Thumb from seed
Nasturtiums are one of those easy to grow cultivars whom thrive on neglect. A poorer soil will encourage profuse flowering and their impact in the garden landscape and summer dish is often under appreciated.
Nasturtiums dislike transplanting so we recommend starting early in thin wall coco pots to be planted out pot and all, or holding off until after the last frosts, direct sow the large nut like seeds where they are to grow. Sow roughly 30cms apart in drills 1.5 to 2cm deep, lightly cover and water.
Companion planting with nasturtiums.
You can use nasturtiums as a trap or sacrificial crop by planting safely away from your veg where they serve to lure aphids away. You can also interplant nasturtiums around your tomatoes, cucumbers aubergines and squash plants where they repel cucumber beetles, aphids and whiteflies. Cheery nasturtium flowers also attract hoverflies and other aphid killers.
As an extra bonus nasturtiums draw cabbage white way from your kales, cabbages and other brassicas whilst the low dense foliage makes an excellent living much.
Using nasturtiums in the kitchen
Add colour and a peppery bite to salads and other dishes with a garnish of crimson and gold-coloured petals. The blue green distinctively shaped leaves look fantastic and taste great too. Nasturtiums are grown as microgreens for their young leaves and their standout taste and impact as a garnish in high end cuisine.
