Nasturtium care at a glance

☀ïļ Light
Full sun to part shade; best flowering in full sun.
💧 Water
Water when the top inch dries; drought-tolerant, and lean conditions boost flowering.
ðŸŠī Soil
Poor to average, well-draining soil; rich soil gives leaves not flowers.
ðŸ’Ļ Humidity
Warm-season annual; frost-sensitive (zones 2-11 as an annual).
ðŸū Toxicity
Non-toxic to cats and dogs; the peppery flowers and leaves are edible for people.

How to propagate Nasturtium

Seed

Difficulty: Very easyTimeline: Germinates in 7-12 days; blooms in 5-7 weeks.
  1. Soak the large seeds overnight to speed germination.
  2. Sow 1/2-1 inch deep directly in place, as they dislike transplanting.
  3. Keep evenly moist until germination.
  4. Thin seedlings to 10-12 inches apart.

Common Nasturtium problems & fixes

Cuttings rot before they root

Too wet or no airflow. Use a free-draining mix, water sparingly, and vent the humidity cover daily.

Cuttings wilt after taking them

Normal at first — keep humidity high under a dome, out of direct sun, until roots form and perk them up.

Powdery mildew on leaves

Poor airflow and damp foliage. Space plants out, water at the base, and improve circulation.
