Answer: In your gardening region, Nasturtiums are annual plants. There are a few reasons for non-blooming; too much nitrogen fertilizer (which encourages lush green growth at the expense of flowers), or not enough sunshine. If your plants have been growing in shady conditions, you'll need to gradually adjust them to sunnier conditions. Start by giving them a few hours of morning sun but protecting them from sunshine from noon on. After a few days of morning sun, extend the time they stay in the sunshine, but give them protection from hot afternoon sunshine. In a few days, move them into sunnier and sunnier spots until they get both morning and afternoon sunshine. This gradual adjustment will keep them from wilting in the hot sunshine and will also encourage lots of brightly colored flowers. Best wishes with your garden!
