Characterized by their round, shield-like leaves and bright, trumpet-shaped flowers, nasturtiums come in a variety of colors, including shades of orange, red, yellow, and cream. Their growth habit is typically sprawling, making them ideal for ground cover or cascading over garden walls and containers.
Originating from South America, nasturtiums have a rich history that dates back to the time of the Aztecs, who valued these plants for their medicinal properties and culinary uses. Over the years, nasturtiums have made their way across the globe, becoming a beloved staple in gardens and kitchens alike.

Planting Nasturtiums in New Zealand
Best Time to Plant Nasturtiums
When it comes to planting nasturtiums in New Zealand, timing is crucial to ensure a thriving garden. The optimal time for planting nasturtiums generally falls between late spring and early summer, specifically from September to December. This timing aligns with New Zealand’s temperate climate, where the risk of frost significantly diminishes after the last frost date in spring.
In cooler regions, particularly in the South Island, it’s advisable to wait until the soil temperature has warmed up to at least 15°C (59°F) before sowing seeds directly into the ground. For gardeners in frost-sensitive areas, starting nasturtium seeds indoors and transplanting them outdoors once the danger of frost has passed can be an effective strategy. This method not only provides a head start but also allows for better control over the growing conditions.
In addition to traditional planting times, local gardening clubs often provide insights on microclimates and specific regional conditions that may affect planting schedules. Engaging with these communities can enhance your understanding of the best practices for planting nasturtiums in your area.
Ideal Growing Conditions
Nasturtiums are remarkably adaptable and can thrive in a variety of conditions, but certain factors can optimize their growth. First and foremost, the choice of soil is vital. Nasturtiums prefer well-draining soil with a pH level between 6.0 and 7.0. Sandy or loamy soils are ideal, as they allow for proper drainage while retaining some moisture. It’s advisable to amend heavy clay soils with organic matter to improve drainage and nutrient availability.
Sunlight is another critical factor in the successful planting of nasturtiums. These vibrant flowers flourish best in full sun, requiring at least six hours of direct sunlight each day. However, in particularly hot regions, providing some afternoon shade can help prevent the leaves from scorching. Conversely, in cooler areas, nasturtiums can tolerate partial shade, although this may result in slower growth and reduced flowering.
Watering is essential, particularly during the initial stages of growth. Nasturtiums require consistent moisture, especially in the early weeks after planting. However, it’s important to avoid overwatering, as this can lead to root rot. A well-draining potting mix or garden bed can help mitigate this risk. Once established, nasturtiums are relatively drought-tolerant, making them a perfect choice for New Zealand gardeners looking for low-maintenance plants.
Propagation Methods
When it comes to propagating nasturtiums, gardeners have a couple of effective methods at their disposal: direct sowing and transplanting. Direct sowing is the most common method, where seeds are sown directly into the garden bed or pots. This method is particularly advantageous in New Zealand’s mild climate, as it allows the plants to acclimate to their environment from the outset.
To sow seeds directly, create small holes or furrows in the soil, spacing them about 25-30 cm apart. Place the seeds approximately 1-2 cm deep and cover them lightly with soil. Ensure that the soil remains moist until germination, which typically occurs within 7 to 14 days, depending on the temperature.
Alternatively, for those who prefer a more controlled environment, starting seeds indoors can be beneficial. This method involves planting seeds in seed trays or pots filled with seed-starting mix. Once seedlings have developed a few true leaves and the outdoor conditions are favorable, they can be carefully transplanted into the garden. When transplanting, handle the seedlings gently to avoid damaging their delicate roots.
Regardless of the propagation method chosen, selecting high-quality seeds is crucial. Many New Zealand gardening clubs offer locally sourced seeds that are well-suited to the local climate. This not only supports local growers but also enhances the chances of successful germination and growth.
Companion Planting and Pest Control
Nasturtiums are not only beautiful and edible; they also serve as excellent companions in the garden. One of the primary benefits of planting nasturtiums alongside other crops is their ability to deter pests. The strong scent of nasturtiums can mask the smell of nearby plants, making it harder for pests like aphids, cabbage moths, and whiteflies to locate their preferred hosts.
For instance, nasturtiums are often planted alongside brassicas, such as cabbage and kale, to protect them from common pests. Additionally, their flowers attract beneficial insects like ladybugs and hoverflies, which prey on harmful pests. This natural pest control method aligns perfectly with the principles of organic gardening, which is gaining popularity among New Zealand gardeners.
Moreover, nasturtiums can improve the overall health of the garden ecosystem. Their deep roots help to break up compacted soil, improving aeration and drainage. This can be particularly beneficial in areas with heavy clay soils, where nasturtiums can thrive while enhancing the growing conditions for nearby plants.
Incorporating nasturtiums into a companion planting strategy not only promotes a healthier garden but also adds a splash of color and flavor to your culinary creations. The edible flowers and leaves can be harvested alongside other crops, providing a delightful addition to salads and garnishes.
In conclusion, planting nasturtiums in New Zealand is a rewarding endeavor that offers both aesthetic and culinary benefits. By understanding the optimal planting times, ideal growing conditions, propagation methods, and the advantages of companion planting, gardeners can cultivate these vibrant flowers successfully. Whether you are a seasoned gardener or a beginner, nasturtiums are an excellent choice for enhancing your garden and culinary experiences. Embrace the joy of planting nasturtiums and enjoy the myriad flavors and colors they bring to your table.
Harvesting Nasturtiums
When to Harvest
Harvesting nasturtiums at the right time is crucial for maximizing their flavor and nutritional value. The best time to begin harvesting is when the flowers and leaves are fully developed but before they start to wilt or lose their vibrancy. Generally, nasturtium flowers can be harvested from late spring to early autumn, depending on your local climate and planting schedule.
For optimal flavor, it’s recommended to harvest flowers in the morning after the dew has dried but before the sun reaches its peak. This timing ensures that the flowers are at their freshest and their essential oils are most concentrated. Leaves, on the other hand, can be harvested throughout the growing season. Look for young, tender leaves, which are typically more flavorful than older, tougher ones.
If you are part of any New Zealand gardening clubs, you may find that members have specific tips or local knowledge about the best times to harvest nasturtiums in your area. Observing your plants closely will help you learn their specific growth patterns and optimal harvesting times.
How to Harvest Nasturtiums
Harvesting nasturtiums requires a gentle touch to avoid damaging the plant. Use clean, sharp scissors or garden shears to snip flowers and leaves. For flowers, cut the stem just below the bloom, ensuring you leave enough stem on the plant to encourage further growth. When harvesting leaves, cut them at the base of the stem, taking care not to pull on the plant, which can cause stress and inhibit future growth.
It’s best to harvest only what you need at the moment to keep the plants healthy and productive. Regular harvesting encourages new growth, so feel free to return to your nasturtiums for additional flowers and leaves as the season progresses.
If you’re new to harvesting or are part of a community gardening initiative, consider joining a workshop or event through local gardening clubs in New Zealand. These clubs often offer hands-on experiences and tips on best practices for harvesting and using edible plants like nasturtiums.
Storage and Preservation
Once you’ve harvested your nasturtiums, proper storage is essential to maintain their freshness. Fresh nasturtium flowers can be stored in the refrigerator for up to a week. Place them in a container with a damp paper towel to keep them hydrated. For leaves, it’s advisable to wash them gently and dry them before storing them in a breathable container, like a paper bag, to prevent moisture buildup.
If you want to preserve nasturtiums for longer periods, consider drying them. To dry nasturtium flowers and leaves, spread them out in a single layer on a clean, dry surface away from direct sunlight. Once fully dried, store them in an airtight container in a cool, dark place. Dried nasturtiums can be used in teas, infused oils, or as a colorful garnish for various dishes.
Another preservation technique is freezing. To freeze nasturtiums, wash and dry the leaves and flowers, then place them in a single layer on a baking sheet. Freeze them until solid, then transfer them to a freezer-safe bag or container. This method allows you to enjoy the bright flavors of nasturtiums even in the off-season.
Incorporating these storage and preservation methods into your culinary routine can enhance your dishes year-round. As you become more familiar with harvesting and using nasturtiums, consider sharing your experiences with fellow members of New Zealand gardening clubs, who may appreciate your insights and tips.
Conclusion
Harvesting nasturtiums is a rewarding experience that allows you to enjoy their vibrant flavors and nutritional benefits.
