As a general guideline, watering once or twice a week should be sufficient, but adjust the frequency based on the specific conditions of your garden.

Life cycle
Seed Planting (Planting Stage): Garden nasturtium is usually grown from seeds. The seeds can be directly sown into the garden bed or started indoors in seed trays 2-4 weeks before the last frost date. The ideal time for planting garden nasturtium seeds is in the spring, once the soil has warmed up and the risk of frost has passed. This is typically around March to May, depending on your specific location.
Germination and Seedling Stage: After planting the seeds, they will germinate within 7-14 days, depending on the conditions. During this stage, the seeds will sprout and develop into small seedlings with their first set of true leaves. Maintain moist soil and provide adequate sunlight or artificial light to support healthy growth.
Vegetative Growth Stage: As the seedlings continue to grow, they will develop more leaves and establish a stronger root system. This vegetative growth stage typically lasts for several weeks, during which the plants will focus on establishing a sturdy foundation before flowering.
Flowering Stage: Garden nasturtiums are known for their vibrant and showy flowers, which come in various colors like orange, yellow, and red. The flowering stage usually begins around 8-10 weeks after planting, depending on growing conditions and variety. This stage can last throughout the summer and into the fall, providing a long-lasting display of colorful blooms.
Harvest Stage: Garden nasturtiums are not only ornamental but also edible. The flowers, leaves, and immature seed pods (known as "capers") are all edible and can be harvested for culinary use. The flowers are typically harvested when fully open and at their peak freshness and color. The leaves can be harvested at any time, depending on your preference. The immature seed pods can be harvested before they become fully mature and hard. Harvesting can begin once the plants start producing flowers, and it can continue until the first frost arrives.Propogation

Spring
Collecting Seeds: Garden nasturtium produces seeds in its seed pods, which are typically formed after the flowers fade. Allow the seed pods to fully mature and dry on the plant. Once dry, the pods will turn brown and start to split open, revealing the seeds inside. Harvest the seeds by gently collecting them from the seed pods.
Direct Sowing: The most common and simplest method of propagating garden nasturtium is by directly sowing the seeds into the desired planting location. This can be done in the garden bed or in containers.
In temperate regions, sow the seeds in spring after the last frost date when the soil has warmed up and the risk of frost has passed.
In warmer climates, garden nasturtium can also be sown in the fall, as they can tolerate cooler temperatures.
Plant the seeds about 1 inch (2.5 cm) deep and 8-12 inches (20-30 cm) apart, as garden nasturtiums tend to spread and vine.
Seed Starting Indoors: If you prefer to get a head start or have a shorter growing season, you can start garden nasturtium seeds indoors. Start the seeds in seed trays or pots about 2-4 weeks before the last expected frost date.
Fill the trays or pots with seed-starting mix and plant the seeds about 1 inch (2.5 cm) deep.
Keep the soil consistently moist and provide adequate sunlight or artificial light for germination and growth.
Transplant the seedlings outdoors once the risk of frost has passed and the seedlings are well-established.
