Planting
Nasturtium is a quick-growing, colorful annual with edible flowers. They like full sun. They’re great as a cover crop and companion plant to other vegetables. They also work well in containers, hanging baskets, and window boxes. Plant 1/2 to 1 inch deep, 10-12 inches apart. Soak and score the seeds to spur the germination process, which takes about 7-10 days. Water regularly, but not overly so.
Harvesting
Cut off faded or dead flowers to prolong blooming. The entire plant is edible and can provide a beautiful garnish to a meal.
Seed Saving
Let the seeds dry on the plant. Some might fall on the ground. You can pick them when they’re still a bit green if you’re worried about critters. Brush off the dirt and you’re good! Store seeds in a cool, dry area.
