How to Grow Nasturtium Flower Plants

Nasturtiums are a flower and a vegetable that begs to be ignored. Grow them in poor soils and if anything, keep the soil dry. Don’t bother with mulch, compost, and fertilizers. They do like full sun but will tolerate partial shade. They make great plants for those areas in your garden that other plants refuse to grow in.

Just remember, keep the soil con the dry side, and they will grow well.

Annual Nasturtium plants are susceptible to frosts and freezes. Protect young plants against unexpected late frosts. And, be ready to cover up the plants in the Fall. If they are still blooming as fall arrives, cover them on cold nights. If you plant them in a flower garden along your house, they just might be the last vegetable you harvest in the fall.

Saving seeds for next year’s crop? It’s easy. Just harvest the brown and dry seed pods before they crack open and spill their seeds. Yes, Nasturtium plants are good re-seeders.

Ideal Soil pH: 5.5 – 7.5.

Eat Your Nasturtium!

The edible leaves can be harvested as soon as several leaves are on the plant. Like any leaf type of plant, they taste better when young and older leaves can be bitter. The flowers are also edible but have less taste. Try using the seeds in pickling for a somewhat different taste.
