Growing tips
Sowing of Climbing Nasturtium
Sow under cover or in place when the soil reaches 12–15 °C. Use a light and draining substrate, maintain regular moisture without excess. Germination occurs in 7 to 14 days. Can be guided on trellis or left as ground cover.
Key takeaway
- Temperature: 15–20 °C
- Humidity: Moist substrate, not soggy
- Light: Full sun after germination
- Transplanting: 3–4 true leaves
Conditions and preparation for planting climbing nasturtium
The climbing nasturtium (Tropaeolum majus) is planted after frosts, when the soil exceeds 12 °C. Install near a support (trellis, fencing) in well-drained and moderately fertile soil — overly rich soil promotes foliage at the expense of flowers.
Key takeaway
- Depth: Crown level with the soil, do not bury
- Spacing: 25–30 cm between plants, 40 cm between rows
- Watering: Basin watering at establishment, then regular in summer
- Mulching / Protection: Light mulch 3 cm, staking as soon as established
Growth and vigor management of the plant
Guide the stems on the support, water regularly without excess, and remove faded flowers to prolong blooming. The nasturtium tolerates moderate drought but produces more flowers with consistently moist soil.
Key takeaway
- Soil type: Well-drained, poor to medium, neutral pH 6.0–7.5
- Maintenance: Staking, removing faded flowers, pinch if growth is too long
- Watering: Regular in summer, keep soil moist, avoid waterlogging
- Preventive action: Good aeration, avoid overly rich soil, light mulching
