Best varieties of Lilies to grow in New Zealand

There are several varieties of lilies that grow well in New Zealand’s climate. Here are some popular choices:

1. Asiatic Lilies (Lilium asiatic): These lilies are known for their vibrant colors and early summer blooming. They are hardy and can tolerate a wide range of soil conditions.
2. Oriental Lilies (Lilium oriental): Oriental lilies are known for their large, fragrant flowers that bloom in mid to late summer. They prefer well-draining soil and partial shade.
3. Trumpet Lilies (Lilium longiflorum): Trumpet lilies produce large, trumpet-shaped flowers and bloom in late summer. They prefer full sun and well-draining soil.
4. Martagon Lilies (Lilium martagon): Martagon lilies are native to New Zealand and are well-suited to the local climate. They have downward-facing flowers and prefer partial shade and moist, well-draining soil.
5. Tiger Lilies (Lilium lancifolium): Tiger lilies are known for their unique, spotted flowers. They are hardy and can tolerate a wide range of soil conditions, but they prefer full sun.
6. Daylilies (Hemerocallis): Although not true lilies, daylilies are popular in New Zealand gardens. They come in a wide range of colors and bloom throughout the summer. They are hardy and can tolerate a variety of soil conditions.

When selecting lilies for your garden, consider factors such as bloom time, height, and color to create a visually appealing display. Additionally, ensure that the soil is well-draining and amend it with organic matter if necessary.

When to plant Lilies in New Zealand

The best time to plant lilies in New Zealand is during the spring season, which is from September to November. This allows the bulbs to establish themselves before the warmer summer months. It is important to note that lilies prefer well-drained soil and a sunny position in the garden.

How to grow

Growing lilies in New Zealand can be a rewarding experience. Here are the steps and considerations to keep in mind:

1. Variety selection: Choose lily varieties that are suitable for New Zealand’s climate. Some popular choices include Asiatic lilies, Oriental lilies, and Trumpet lilies. Consider factors such as bloom time, color, and height when selecting varieties.
2. Site selection: Lilies prefer a sunny location with well-drained soil. Choose a spot that receives at least six hours of direct sunlight per day. Avoid areas prone to waterlogging, as excess moisture can cause bulb rot.
3. Soil preparation: Prepare the soil by removing any weeds, rocks, or debris. Lilies prefer slightly acidic to neutral soil with good organic matter content. Incorporate well-rotted compost or aged manure into the soil to improve its fertility and drainage.
4. Planting time: Lilies are typically planted in early spring or autumn. In New Zealand, autumn planting is more common as it allows the bulbs to establish roots before winter. However, if you choose to plant in spring, ensure the soil has warmed up sufficiently.
5. Planting depth: Dig a hole that is about three times the height of the bulb. Place the bulb in the hole with the pointed end facing upwards. Cover the bulb with soil, ensuring that the top of the bulb is about 10-15 cm below the soil surface.
6. Spacing: Space lily bulbs at least 15-20 cm apart to allow for proper air circulation and growth. If planting multiple bulbs, consider creating groupings or clusters for a more visually appealing display.
7. Watering: Lilies require regular watering, especially during dry periods. Keep the soil consistently moist but not waterlogged. Avoid overhead watering, as wet foliage can lead to fungal diseases. Water at the base of the plants to minimize moisture on the leaves.
8. Mulching: Apply a layer of organic mulch, such as straw or bark chips, around the lilies. Mulching helps conserve soil moisture, suppress weeds, and regulate soil temperature.
9. Fertilizing: Lilies benefit from regular feeding. Apply a balanced slow-release fertilizer or a bulb-specific fertilizer in early spring and again after flowering. Follow the manufacturer’s instructions for application rates.
10. Staking: Tall lily varieties may require staking to support their stems and prevent them from bending or breaking. Install stakes or plant supports early in the growing season to avoid damaging the bulbs or roots.
11. Pests and diseases: Keep an eye out for common pests such as aphids, slugs, and snails. Use organic pest control methods or insecticidal soaps to manage infestations. Lilies can also be susceptible to diseases like botrytis blight and lily mosaic virus. Ensure good air circulation and avoid overhead watering to minimize disease risks.
12. Deadheading and maintenance: Remove spent flowers to encourage continuous blooming and prevent seed formation. After the foliage turns yellow in late summer or autumn, cut it back to ground level. This allows the bulbs to store energy for the next growing season.

By following these steps and considerations, you can enjoy the beauty and fragrance of lilies in your New Zealand garden.

When do Lilies bloom in New Zealand?

Lilies typically bloom in New Zealand during the summer months, which is from December to February. However, the exact blooming period can vary depending on the specific type of lily and the region in which it is grown. Some lilies may start blooming as early as November, while others may continue blooming into March. It is important to note that New Zealand has diverse climate zones, so there may be some variations in blooming times across different regions of the country.

Other considerations

When growing lilies in New Zealand, there are several important considerations to keep in mind:

1. Climate: Lilies thrive in temperate climates, so it’s important to choose lily varieties that are suitable for your specific region in New Zealand. Some lilies prefer cooler climates, while others can tolerate warmer conditions. Be sure to check the recommended hardiness zones for each lily variety before planting.
2. Soil: Lilies prefer well-draining soil that is rich in organic matter. Before planting, amend the soil with compost or well-rotted manure to improve its fertility and drainage. Avoid heavy clay soils, as they can cause waterlogging and root rot.
3. Sunlight: Lilies require at least 6-8 hours of direct sunlight per day to thrive. Choose a sunny spot in your garden that receives ample sunlight throughout the day. If you have limited sun exposure, consider planting lilies in containers that can be moved to sunnier areas.
4. Watering: Lilies prefer evenly moist soil, but they don’t like to sit in waterlogged conditions. Water the plants deeply once or twice a week, depending on the weather and soil conditions. During hot and dry periods, you may need to increase the frequency of watering.
5. Mulching: Apply a layer of organic mulch around the base of lilies to help conserve moisture, suppress weed growth, and regulate soil temperature. Use materials like straw, wood chips, or compost, and ensure that the mulch does not touch the lily stems to prevent rot.
6. Fertilization: Lilies are heavy feeders and benefit from regular fertilization. Apply a balanced, slow-release fertilizer in early spring when new growth emerges. Additionally, you can supplement with a liquid fertilizer every 4-6 weeks during the growing season to promote healthy foliage and abundant blooms.
7. Pests and Diseases: Keep an eye out for common pests such as aphids, lily beetles, and slugs, which can damage lilies. Use organic pest control methods or insecticidal soaps to manage infestations. Lilies can also be susceptible to fungal diseases like botrytis and powdery mildew. Ensure good air circulation around the plants and avoid overhead watering to minimize the risk of disease.
8. Staking: Some lilies, especially taller varieties, may require staking to support their stems and prevent them from bending or breaking. Install stakes or plant lilies near other sturdy plants that can provide natural support.
9. Winter Care: In colder regions of New Zealand, lilies may require winter protection. Apply a layer of mulch or straw around the base of the plants to insulate the bulbs from freezing temperatures. Consider lifting and storing bulbs in a cool, dry place if your region experiences severe frosts.

By considering these important factors, you can successfully grow lilies in New Zealand and enjoy their beautiful blooms year after year.
