Description
Introduction to Alstroemeria
Alstroemeria ‘Yellow King,’ also known as the Peruvian Lily, Lily of the Incas, Princess Lilies, or Parrot Beak, is a tuberous-rooted herbaceous perennial. Belonging to the Alstroemeriaceae family, it is native to select regions in South America, including Chile, Brazil, and Peru. Once established, it is tough, reliable, and low-maintenance, blooming profusely for up to nine months in most climates. Its striking bright yellow blooms make Alstroemeria ‘Yellow King’ a favourite in gardens and floral arrangements. Suitable for large pots, containers, garden beds, and borders, its renowned long-lasting, fragrance-free flowers can last over two weeks in a vase. Their lack of fragrance makes them an ideal choice for allergy sufferers who may find scented gardens challenging.
Growing Alstroemeria ‘Yellow King’ in Various Australian Climates
Thriving in various climates, Alstroemeria ‘Yellow King’ can be successfully grown in cool to subtropical regions of Australia, including New South Wales, Victoria, Queensland, South Australia, Western Australia, Tasmania, and the Australian Capital Territory. While it is drought-hardy and tolerant of light frosts, making it ideal for challenging environments, growing it in arid and semi-arid regions can be difficult due to extreme temperatures and sparse rainfall. In these areas, it requires careful management of moisture levels and protection from intense heat to thrive.
How to Store Alstroemeria
If you need to store Alstroemeria tubers before planting them, especially to wait until after winter, follow these steps to ensure they remain healthy and viable. Upon receiving the plant, gently brush off any excess soil without washing it to prevent moisture retention. Allow the plant to air dry for a few hours in a well-ventilated area to remove surface moisture and reduce the risk of fungal infections.
Store the plant in a breathable container such as a paper bag, cardboard box, or wooden crate. Surround them with a dry, inert material like peat moss, vermiculite, or dry sand to keep them dry and prevent them from touching each other. Store the container in a cool, dark, and dry place with an ideal temperature range of 1.5-10°C (35-50°F), such as a garage or refrigerator, ensuring the area is frost-free and has good air circulation.
Periodically check the stored plants for any signs of mould, rot, or dehydration, and remove any affected plants immediately to protect the healthy ones. When ready to plant in spring, take them out of storage a few days prior, allowing them to acclimate to room temperature. If they seem dry, soak them in lukewarm water for about 30 minutes to rehydrate them before planting. By following these steps, you can store your Alstroemeria over winter and ensure they remain healthy and ready for planting when the weather is favourable.
Preparing to Grow Alstroemeria ‘Yellow King’
Alstroemeria ‘Yellow King’ thrives in various Australian climates, from cool to subtropical regions. It is essential to provide well-drained, organic-rich soil and consider the specific climate needs for optimal growth. Depending on your region, adjustments may be necessary to ensure the plant receives the right amount of sunlight, shade, and moisture.
Planting and Care Instructions
Since these can be planted from March onwards, you can plant them immediately or store them for later in the year. When you receive your bare-rooted Alstroemeria, start by soaking the roots in lukewarm water for about 30 minutes to an hour to rehydrate them. Prepare a sunny to partially shaded spot (refer to your climate region information) with well-draining, organically rich soil. Loosen the soil to a depth of about 12-15 inches (30-38 cm) and incorporate compost or well-rotted manure to enhance soil fertility and structure. Dig a hole large enough to accommodate the roots without bending them, place the roots in the hole with the roots just below the soil surface, and space the plants 12-18 inches (30-50 cm) apart. Take care not to bury shoots too deep. Backfill the hole gently, firming the soil around the roots, and water thoroughly to settle the soil. Apply a layer of organic mulch (straw, bark, compost) around the plants to retain moisture, regulate soil temperature, and suppress weeds, ensuring the mulch is kept away from the plant’s base to prevent rot. Continue to water regularly, keeping the soil consistently moist but not waterlogged, and avoid fertilising until the plants show signs of new growth. Protect newly planted Alstroemeria from extreme weather conditions, such as strong winds or heavy rains, until they are well established. Keep the soil moist until the plants begin to grow. Following these steps will help your bare-rooted Alstroemeria establish well and thrive in your garden.
Climate-Specific Growing Instructions for Alstroemeria ‘Yellow King’
Cool to Temperate Climates (Victoria, Tasmania, Australian Capital Territory)
Planting Time: March onwards. Planting in autumn allows the plants to establish roots and prepare for harsh winters and the next growing season. Alternatively, plant in late winter to early spring (August to September) to allow roots to establish before the colder weather sets in and to avoid extreme frost.
Location: Sunny spots with well-draining, organically rich soil to prevent root rot; light shade during hot weather to protect the plant from intense heat.
Mulching: Apply organic mulch (straw, bark, compost) when planting to retain moisture, regulate soil temperature, and suppress weeds; refresh in late summer or early autumn to maintain effectiveness. In winter, apply a thick layer of mulch to protect the roots from frost and maintain soil moisture.
Watering: Water weekly, ensuring soil remains moist but not waterlogged; adjust based on weather conditions to provide adequate moisture. In winter, reduce watering to prevent root rot, as the plant is dormant and requires less moisture.
Fertilising: Apply a general, slow-release fertiliser as a top dressing before the flowering season in spring to support growth and blooming; also fertilise in autumn to boost overall plant health. Do not fertilise in winter as the plant is dormant and not actively growing.
Pruning: Regularly remove spent flowers to encourage continuous blooming and conserve the plant’s energy. Trim dead foliage in late autumn to maintain plant health and appearance, making sure to cut back to 50 mm from the base. Top tip: When harvesting flowers, avoid cutting stems to prevent disease. Instead, gently pull the stem from the base to keep the plant’s root section clean and promote healthy growth.
Winter Care: Reapply thick mulch at the start of winter for frost protection and to maintain soil temperature; reduce watering during dormancy to prevent root rot.
Temperate to Subtropical Climates (New South Wales, Queensland)
Planting Time: March onwards. Planting in autumn allows the plants to establish roots and prepare for intense summer heat. Alternatively, plant in early to mid-spring (September to October) to ensure warm temperatures for root establishment.
Location: Sunny spots with well-draining, organically rich soil; partial shade during the hottest part of the day to prevent heat stress and protect the plant from intense sunlight.
Mulching: Apply organic mulch (straw, bark, compost) when planting to retain moisture, regulate soil temperature, and suppress weeds; refresh as needed to maintain effectiveness. In winter, apply a thick layer of mulch to protect the roots from temperature fluctuations and maintain soil moisture.
Watering: Water weekly, increasing during dry spells to keep the soil consistently moist but not waterlogged; use a soaker hose or drip irrigation for deep watering to ensure the roots receive adequate moisture. In winter, reduce watering to prevent root rot, as the plant is dormant and requires less moisture.
Fertilising: Apply a general, slow-release fertiliser as a top dressing before the flowering season in spring to support growth and blooming; also fertilise in autumn to boost overall plant health. Do not fertilise in winter as the plant is dormant and not actively growing.
Pruning: Prune spent flowers regularly to encourage continuous blooming and prevent energy wastage; trim dead foliage in late autumn to maintain plant health and appearance, making sure to cut back to 50 mm from the base. Top tip: When harvesting flowers, avoid cutting stems to prevent disease. Instead, gently pull the stem from the base to keep the plant’s root section clean and promote healthy growth.
Winter Care: Reduce watering during dormancy to prevent root rot; apply thick mulch in winter for frost protection and to maintain soil temperature. Ensure the mulch is kept away from the plant’s base to avoid excess moisture and potential rot.
Mediterranean Climates (South Australia, Western Australia)
