Alkarty — Nasturtium (Tropaeolum majus) Seeds

Easy, edible, and dazzling — nasturtiums are perfect for beginners, containers, beds and companion planting. This Alkarty-focused guide explains how to grow from seed, care for plants, the health & garden benefits, and key advantages.

Alkarty product notes

Alkarty lists a nasturtium flower seeds product (pack contains multiple seeds and a short "learn how to grow" note). Use the packet instructions alongside the general guidance below for best results. :

1) How to grow nasturtium from seed

Indoor seed starting

  1. When: Start 3–4 weeks before the last expected frost if you want an early crop; otherwise seed outdoors after frost risk has passed. :
  2. Soak (optional): Soaking larger nasturtium seeds overnight can speed germination, but it's not required.
  3. Medium: Use a free-draining seed mix in cells or small pots; moisten before sowing.
  4. Sowing: Plant seeds 1/2"–1" (1.2–2.5 cm) deep or press into surface (they germinate readily). Keep soil moist until sprouting (usually 7–14 days).
  5. After germination: Move seedlings to bright light, pot up when they have true leaves, and harden off 7–10 days before planting out. Avoid transplanting very late — nasturtiums dislike root disturbance. :

Direct sow outdoors (recommended for best success)

  1. Timing: Sow in spring after all danger of frost when soil has warmed. In mild climates sow earlier.
  2. Site: Choose full sun for the brightest blooms (some varieties tolerate partial shade). Ensure very good drainage.
  3. Sow & space: Plant seeds 1/2"–1" deep, space 8–12" (20–30 cm) apart for bush types; vining types need supports/trellis and more room. Thin to strongest seedlings.
  4. Care while germinating: Keep seed bed evenly moist; germination typically 7–14 days but can take longer in cool soils.

2) Care & ongoing maintenance

AspectRecommendation
Light Full sun gives the best and most abundant flowers; some shade in very hot climates is tolerated.
Soil Prefer poorer, well-drained soil. Rich, high-nitrogen soils produce lush foliage but fewer flowers — avoid over-fertilizing.
Watering Keep evenly moist for seedlings. Once established nasturtiums are fairly drought tolerant — water deeply but infrequently; allow topsoil to dry between waterings. :
Support Provide trellis or supports for vining types; keeping vines up prevents flowers and leaves from getting dirty and encourages better airflow.
Pests & disease Nasturtiums can attract aphids (they're used as trap crops) and may get fungal leaf spots in humid conditions — good airflow, avoiding overhead watering, or using them as sacrificial trap plants helps.
Pruning & seed saving Deadhead to extend flowering or let some flowers set seed — nasturtiums readily self-seed; collect dry seed pods for saving next season.

3) Benefits (health, culinary & garden)

  • Edible & nutritious: Leaves, flowers and immature seedpods are edible with a peppery, watercress-like flavor and provide vitamin C and minerals. Use fresh in salads, as garnishes, or pickled as caper substitutes.
  • Natural pest management: Nasturtiums act as trap crops for aphids and whiteflies, protecting other plants.
  • Wildlife & pollinators: Flowers attract bees and beneficial insects, supporting garden biodiversity. :
  • Soil & landscape uses: Useful as quick groundcover, in containers, hanging baskets, or on slopes — many varieties are low-maintenance and drought tolerant once established.
  • Medicinal research: Preliminary studies show nasturtium extracts have antimicrobial and other potential health properties (consult healthcare sources before medicinal use).

4) Advantages of growing Alkarty nasturtium seeds

  • Economical & easy: Seeds are inexpensive and germinate easily — perfect for beginners and bulk planting.
  • Versatile varieties: Bush and vining types suit containers, beds or vertical spaces — pick the type you want when buying seeds.
  • Low input needs: Thrive in poorer soils with minimal fertilizer and modest watering once established.
  • Dual-purpose: Beautiful flowers plus edible leaves/flowers give both ornamental and culinary value.

Quick start checklist

  • Sow outdoors after last frost; or start indoors 3–4 weeks before and transplant after hardening off.
  • Plant 1/2"–1" deep; space 8–12" apart (vining types need supports).
  • Keep evenly moist until germination (7–14 days); then moderate watering.
  • Avoid high-nitrogen fertilizers — poorer, well-drained soil encourages blooms.
  • Use as trap crop for pests, harvest edible flowers/leaves, and save seeds from dry pods.
