Nasturtiums are a joy to grow, requiring minimal care and soil inputs. They prefer nitrogen-poor soil, which encourages flower production over lush foliage growth. Adding a layer of mulch and providing some afternoon shade can help keep the soil cool and your nasturtiums happy in hot summer areas. Nasturtium seeds are quite large and easy to plant, which makes them an excellent choice for young budding gardeners. Consider adding them to your vegetable garden for their peppery flavors and pollinator-attracting qualities. Smaller varieties can be grown in pots while trailing types can be trained to climb fences and trellises with some assistance by tying them in. Finally, place a handful of blooms in old sea-green glass canning jars for the perfect bouquet.
