Growing Nasturtium

Introduction to Nasturtium

Nasturtiums are a gardener's delight, boasting vibrant blooms and edible leaves. They thrive in poor soil, making them a versatile choice for almost any garden.

Their peppery taste adds a unique flair to salads and dishes. Imagine your garden filled with the fiery hues of these flowers.

Why Choose Nasturtium?

Easy to Grow: Nasturtium adapts well to neglect.

No green thumb needed here!

Did you know? Nasturtium thrives even in rocky, sandy, and neglected soil.

Planting Nasturtium

Site Selection

Nasturtium loves the sun. Find a sunny spot, and you’re halfway there.

Although they tolerate partial shade, full sun brings out their best colors.

Soil Requirements

Forget the fertilizer; nasturtium prefers poor, well-drained soil. Too much richness produces more leaves than flowers.

Avoid excessive nutrients. They thrive where other plants may not.

Pro tip: Direct sowing nasturtium seeds in lean soil results in more prolific blooms.

Sowing Seeds


Plant seeds in spring after the last frost. Soil temperatures around 55-65°F (13-18°C) are ideal for germination.


  • Soak seeds overnight for faster germination.
  • Plant each seed about half an inch deep.
  • Space them 10-12 inches apart.

Water the soil lightly after planting. Nasturtiums germinate in 7-10 days.

Caring for Nasturtium


Keep the soil slightly moist but not waterlogged. Overwatering can lead to root rot.

Pest Control

Nasturtiums can attract aphids. Regularly check under the leaves and use insecticidal soap if needed.

They're also good companion plants, deterring pests from other crops.

Nasturtiums repel harmful insects while attracting beneficial ones like bees.

Harvesting and Using Nasturtiums


Pick flowers and leaves early in the morning for the best flavor. Regular harvesting encourages more blooms.

Culinary Uses

  • Flowers add color and spice to salads.
  • Leaves make a zesty pesto.
  • Seeds can be pickled and used like capers.

Experimenting with nasturtium in the kitchen opens up a world of flavors.
