Planting Nasturtiums: A Comprehensive Guide
When to Plant Nasturtiums
When it comes to planting nasturtiums in New Zealand, timing is crucial for successful growth. Nasturtiums thrive in warm conditions, making spring the ideal season for planting. In most regions, the best time to sow seeds is after the last frost date, typically between late September and early November. However, it’s essential to check local frost dates, as they can vary significantly across different areas of New Zealand.
For those living in warmer regions, such as Northland and Auckland, you may even start planting nasturtiums as early as late August. Conversely, in cooler areas like Otago or Southland, it’s wise to wait until mid-October to ensure that the risk of frost has passed.
Additionally, consider the seasonal changes when planning your planting schedule. Nasturtiums can also be planted in late summer for a fall harvest, particularly if you’re looking to enjoy their vibrant blooms and edible flowers into the cooler months.
Preparing Your Garden for Nasturtiums
Before you embark on planting nasturtiums, you need to prepare your garden properly. The first step is to evaluate your soil conditions. Nasturtiums prefer well-draining soil with a slightly acidic to neutral pH (around 6.0 to 7.0). Heavy clay soils can lead to root rot, so it’s essential to amend them for optimal growth.
To improve soil drainage and fertility, consider incorporating organic matter such as compost or well-rotted manure. This not only enriches the soil but also enhances its structure, allowing for better root development. If your soil is particularly poor, you may want to consider raised beds or container gardening, which allows for greater control over soil quality.
In terms of sunlight, nasturtiums thrive in full sun but can tolerate partial shade. If your garden has areas that receive a mix of sun and shade, don’t hesitate to plant nasturtiums there; they will still produce vibrant blooms and delicious leaves.
Step-by-Step Planting Guide
Now that you have chosen the right time and prepared your garden, it’s time to delve into the actual planting process. You have two primary options: sowing seeds directly into the soil or transplanting seedlings.
Choosing Seeds vs. Seedlings
If you decide to go with seeds, look for high-quality nasturtium seeds from a reputable supplier. Direct sowing is often preferred as it allows the plants to establish themselves in their final location, minimizing transplant shock. However, if you want to get a head start on the growing season, you can start seeds indoors about 4-6 weeks before the last frost date.
If you opt for seedlings, ensure they are healthy and robust before transplanting them into your garden. This method can be particularly beneficial if you’re looking to fill in gaps in your garden quickly.
Sowing Techniques: Direct Sowing vs. Transplanting
For direct sowing, plant the seeds about 1.5 cm deep and space them approximately 20-30 cm apart to allow for their sprawling growth. If you’re planting in rows, maintain a distance of about 30 cm between rows.
When transplanting seedlings, dig a hole slightly larger than the root ball and gently place the seedling in the hole, ensuring that the top of the root ball is level with the surrounding soil. Fill in the hole with soil and water thoroughly to eliminate air pockets.
Spacing and Depth Guidelines
Proper spacing is crucial for the growth of nasturtiums. Crowded plants can lead to poor air circulation, making them more susceptible to pests and diseases. As a general rule, provide at least 20-30 cm between each plant.
In terms of depth, sow seeds about 1.5 cm deep. If you’re transplanting seedlings, ensure the root ball is covered but avoid burying the stem, as this can cause rot.
Care After Planting
Once you have successfully planted your nasturtiums, the next step is to ensure they receive the right care. Watering is vital, especially during the initial establishment phase. Keep the soil consistently moist but not soggy, as overwatering can lead to root rot.
As the plants mature, they will become more drought-tolerant. However, during dry spells, ensure they receive adequate water, particularly if you’re growing them in containers.
Fertilizing is another aspect of care to consider. While nasturtiums are not heavy feeders, a balanced, organic fertilizer can help promote vigorous growth and flowering. Apply the fertilizer according to package instructions, typically once in early spring and again mid-season.
Encouraging Growth and Blooming
To maximize the beauty and productivity of your nasturtiums, consider deadheading spent flowers regularly. This practice encourages the plant to produce more blooms and can extend the flowering period. Additionally, pruning back any overly leggy growth will help maintain a bushy, attractive shape.
In summary, planting nasturtiums in your New Zealand garden involves careful planning and preparation. By selecting the right time, preparing your soil, and following proper planting techniques, you can enjoy a vibrant display of color and flavor from these delightful edible flowers. Whether you’re growing them for their culinary uses or ornamental appeal, nasturtiums are sure to enhance your garden experience.
As you embark on your journey of planting nasturtiums, remember that patience and care are key. With the right conditions and attention, your nasturtiums will flourish and provide an abundance of beautiful blooms and delicious leaves to enjoy throughout the growing season.
Caring for Your Nasturtiums
Watering and Fertilizing
Proper watering and fertilizing are crucial for the healthy growth of nasturtiums. These vibrant plants thrive in well-drained soil and prefer a moderate amount of water. Overwatering can lead to root rot, while underwatering can stunt their growth. When planting nasturtiums, aim to maintain consistent soil moisture, especially during dry spells.
A good rule of thumb is to water your nasturtiums deeply but infrequently. This encourages the roots to grow deeper into the soil, making the plants more resilient to drought conditions. Generally, watering once a week is sufficient, but this may vary depending on your local climate and soil conditions. During particularly hot or dry periods, you may need to adjust your watering schedule accordingly.
Fertilizing is another important aspect of caring for nasturtiums. These plants are not heavy feeders, and in many cases, they thrive in poor soil conditions. However, if your soil is particularly lacking in nutrients, a light application of a balanced, slow-release fertilizer can promote better growth. It’s best to fertilize nasturtiums at the time of planting and then again mid-season if needed. Be cautious not to over-fertilize, as this can lead to excessive foliage growth at the expense of flowers.
Pests and Diseases
Nasturtiums are generally hardy plants, but they can still fall victim to various pests and diseases. In New Zealand, common pests that may affect nasturtiums include aphids, whiteflies, and spider mites. Aphids, in particular, are notorious for sucking the sap from young leaves and stems, which can weaken the plant and lead to stunted growth.
To manage these pests organically, consider introducing beneficial insects such as ladybugs and lacewings, which feed on aphids. Additionally, you can use insecticidal soap or neem oil to treat infestations. These organic solutions are effective and safe for both the plants and the environment.
Diseases like powdery mildew can also affect nasturtiums, particularly in humid conditions. To prevent this, ensure good air circulation around your plants by spacing them adequately and avoiding overcrowding. If you notice signs of powdery mildew, remove affected leaves immediately and consider applying a fungicidal spray if the problem persists.
Pruning and Maintenance
Pruning is an essential part of maintaining the health and appearance of your nasturtiums. Regularly removing dead or yellowing leaves not only enhances the plant’s aesthetic appeal but also helps to prevent disease. Additionally, deadheading—removing spent flowers—encourages the plant to produce more blooms throughout the growing season.
When pruning nasturtiums, use clean, sharp scissors or garden shears to make precise cuts. Aim to prune during the morning hours when the plant is hydrated, which can help reduce stress on the plant. Focus on cutting back any leggy growth to promote a bushier appearance and encourage more flowering.
In terms of maintenance, keep an eye on the overall health of your nasturtiums. Regularly inspect the plants for signs of pests or diseases, and take action promptly if you notice any issues. Additionally, consider mulching around your nasturtiums to help retain soil moisture and suppress weeds. Organic mulch, such as straw or wood chips, can be particularly beneficial.
When it comes to planting nasturtiums, spacing is also a vital consideration. Ensure that you provide enough room between plants to allow for proper airflow and growth. This not only helps to prevent disease but also allows each plant to thrive without competing for resources.
Companion Planting with Nasturtiums

This gardening technique can enhance growth, deter pests, and improve overall garden health. Nasturtiums are particularly well-suited for companion planting due to their natural pest-repelling properties and their ability to attract beneficial insects.
When selecting companion plants for nasturtiums, consider those that can benefit from their presence. For example, nasturtiums are known to deter aphids and other pests, making them an excellent companion for vegetables like tomatoes, cucumbers, and brassicas. By planting nasturtiums alongside these crops, you can create a more balanced ecosystem in your garden.
Best Companion Plants for Nasturtiums
