Growing Peruvian Lilies in New Zealand

Growing Peruvian Lilies in New Zealand

New Zealand's climate is generally conducive to growing Peruvian lilies. The country's mild temperatures and varying regional climates provide an excellent environment for these plants to thrive. These plants thrive in areas with mild temperatures and well-drained soil, which are common in many parts of New Zealand. Here's how you can successfully cultivate these beauties in your NZ garden.

Best Location and Planting Advice

Peruvian Lilies thrive in most NZ climates, making them ideal for borders, pots, or cut flower gardens. In this article, we’ll cover everything you need to know to grow healthy, flowering Peruvian Lilies in your own garden.

Choosing the Right Location

• Select a spot that receives full sun to partial shade. Peruvian lilies prefer a location that is protected from wind, which can damage their stems and flowers. In regions prone to high winds, consider planting them where they will receive generous shelter. Additionally, ensure that the selected site has enough space to accommodate their growth to avoid overcrowding and for them to put on an amazing display.

Preparing the Soil

• The best soil for Peruvian lilies is rich, well-draining, and slightly acidic. Before planting, work organic matter like compost into the soil to improve its fertility and drainage. This not only enhances soil structure but also increases its nutrient content, providing a better growing medium for the lilies. If the soil is poorly drained and this cannot be corrected, we recommend not attempting to grow them there and choose an alternate location.

Planting

• When planting potted plants, do not try and spread out the roots as this can damage them. Rather, place the plant in the hole and ensure the soil is at the same level as the soil in the pot it was growing in. Consistent watering during the initial weeks after planting is crucial to help them settle and establish a robust root system.

Peruvian Lily Care Tips

Caring for Peruvian lilies involves regular attention to watering, feeding, and pruning. By dedicating time to these tasks, you can ensure your plants remain healthy and continue to bloom profusely. Here are some tips to keep your plants healthy and blooming:

Watering

• Peruvian lilies need consistent moisture, especially during their growing season. Water them regularly, but ensure the soil does not become waterlogged, as this can lead to root rot. Using a drip irrigation system can help provide consistent moisture while preventing excess water accumulation. Mulching around the base of the plants can also help retain soil moisture and keep roots cool.

Feeding

• Feed your lilies with garden fertiliser in early spring and again in mid-summer. This will provide the nutrients they need for robust growth and vibrant blooms. Be sure not to over-fertilise the plants as this can cause damage to the plant.

Pest and Disease Management

• Peruvian lilies are relatively pest-resistant, but you should still watch for common garden pests like aphids and slugs. Regular monitoring of your plants can help you catch any issues early. Use organic pest control methods or insecticidal soap if necessary to manage infestations. Encouraging beneficial insects, such as ladybugs, can also help control pest populations naturally.

Peruvian Lily Pruning

Pruning is essential for maintaining the health and appearance of your Peruvian lilies. Regular pruning helps prevent diseases and encourages more vigorous flowering.

• Deadheading: Remove spent blooms to encourage more flowers and prevent the plant from wasting energy on seed production. This practice also helps maintain a neat appearance in your garden.
• Cutting Back: At the end of the blooming season, cut back the stems to about 10 cm above the ground. This helps prepare the plant for the next growth cycle. Regularly check for damaged or diseased stems and remove them promptly to maintain plant health.

Propagation Techniques

Peruvian lilies can be propagated through division, which is best done every few years to prevent overcrowding and rejuvenate the plants. Regular propagation ensures your plants remain vigorous and productive. Here's how:

• Timing: The best time to divide Peruvian lilies is in early spring or late summer. These periods allow the plants to recover quickly and establish before extreme weather conditions.
• Process: Carefully lift the clump of lilies from the ground and gently separate the tubers. Replant the divisions at the same depth they were growing before. Ensure each division has a healthy set of roots and stems to support new growth. Water thoroughly after replanting to help them settle in their new location.

Understanding Peruvian Lily Varieties

Peruvian lilies come in a dazzling array of colors and sizes. Their diversity means there's a variety to suit every garden style and colour scheme. Some popular varieties include:

• Alstroemeria Inca Ice: Known for its soft, cream-colored petals with a hint of pink, 'Inca Ice' can add a touch of elegance to any garden. Its subtle hues make it a perfect companion plant for more vivid flowers.

Frequently Asked Questions

How long do Peruvian lilies bloom?

Peruvian lilies typically bloom from late spring to early fall, providing a long season of colorful flowers. Their extended blooming period makes them an excellent choice for gardeners looking to maintain vibrant colour throughout the growing season. With proper care, you can extend their flowering period even further.

Are Peruvian lilies toxic to pets?

While they are generally safe, some varieties of lilies can be toxic to pets if ingested. Cats are particularly sensitive to lily toxicity, so it's best to keep them out of reach of curious cats and dogs. If you have pets, consider planting these lilies in areas that are inaccessible to them or opt for non-toxic plant varieties.

Can Peruvian lilies be grown in containers?

Yes, Peruvian lilies can thrive in containers. Choose a large pot with good drainage, and use a high-quality potting mix to ensure adequate root growth. Regular feeding and watering are crucial for container-grown lilies, as their confined environment can lead to quicker nutrient depletion. Consider using a pot with a built-in reservoir to help maintain consistent moisture levels.
