nasturtium instructions

PLANTING

  • You can start the seeds indoors 4 to 6 weeks before the last spring frost. 
  • Plant nasturtium seeds in early spring in moist, well-drained soil in full sun. They can grow in partial shade, but they will not bloom as well.
  • Nasturtiums prefer poorer soils and they do not need fertilizers (unless your soil is extremely poor). Fertile soil will produce fewer blooms and more foliage.
  • Plant the seeds about half an inch deep and 10 to 12 inches apart. Plants should appear in 7 to 10 days.

CARE

  • Water regularly throughout the growing season, but be careful not to over-water your plants.
  • Cutting off the faded/dead flowers will prolong blooming.
  • If you’re growing nasturtiums in containers, they may need to be trimmed back occasionally over the growing season.
