• Nasturtiums do well in poorer soils and do not typically need extra fertilizer (unless your soil is extremely poor). Too much nitrogen will encourage more foliage than flowers.
• Soil should be well-draining.
• Plant nasturtiums in full sun (6–8 hours of sunlight) for the best results. They will grow in partial shade (3–6 hours of sunlight), but won’t bloom as well.
• Be conscious of the growing habit of the type of nasturtium you’re growing. Plan to provide supports for trailing types.

• How to Plant

• Sow the seeds about half an inch deep and 10 to 12 inches apart in the garden.
• Plants should appear in 7 to 10 days.
  

  How to Care:

  • Water regularly throughout the growing season, but be careful not to overwater your plants. Nasturtiums are somewhat drought tolerant, but still prefer to grow in moist soil. Plus, water-stressed plants will have subpar blooms and flavor.
  • 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. This encourages the plants to produce new foliage.
  • In summer, nasturtiums may stop blooming if they become heat-stressed. Their flavor may become more intense, too. Keeping them sufficiently watered can help to mitigate the effects of extreme temperatures.

Nasturtium flowers are said to symbolize patriotism.  Best suitable for container garden. creeper type can be trained in pergolas
