Soil & Water: Climbing nasturtiums are easy to grow in any well-drained soil. Fertilizer is usually not necessary and too much nitrogen will create bountiful foliage without much flowering. You'll need to train young plants onto their supports with loose ties, then they'll climb easily and bloom non-stop. Do not let plants dry out during blooming season.

Planting & Growing:To Start Outdoors: Sow seeds in spring, once all danger of frost is over, in full sun (or part shade in hot climates). Poke seeds into well-worked soil about 1" deep and 3 - 4" apart. Press soil firmly over the seeds and keep moist. When seedlings are large enough to handle, thin to stand 10" apart, or 6 - 8" apart if training seedlings up vertical supports. To Start Early Indoors: Sow 2 seeds in individual 4" pots of well-drained seed starting mix 3 weeks before last expected frost date. Cover 1" deep. Provide a strong light source. When seedlings have several sets of leaves, pinch out the weaker seedling leaving 1 seedling per pot. When weather is evenly in the 50's, gradually acclimate to outdoor conditions. Transplant as above in full sun.
