Description
Hippeastrums, also known as Amaryllis, are renowned for their spectacular trumpet-shaped flowers that come in a dazzling array of colours. From rich reds and pinks to pristine whites and striking multicoloured patterns, these large and beautiful blooms grace gardens and containers with their vibrant presence during spring and summer. Emerging from bare bulbs, Hippeastrum flowers can last for several weeks. Typically, each flower lasts about 2-3 weeks, and a single bulb can produce multiple flower stalks, each with several blooms. This results in an extended blooming period, often ranging from 6-8 weeks in total. Keep in mind that red varieties typically bloom earlier than white varieties, with others falling somewhere in between, due to their flower pigmentation. However, the exact timing can vary depending on growing conditions.
With proper care, such as adequate watering, appropriate lighting, and suitable temperatures, the blooming period can be maximised, allowing you to enjoy their stunning flowers for an extended time. Even after the blooms fade, the glossy foliage adds ornamental value to the garden or container throughout the warmer months before naturally receding in winter.
When planting Hippeastrum bulbs, choose a well-draining potting mix with good organic content for pots, or use well-drained, organically rich soil for garden beds. Planting in pots is ideal from September to December, while autumn and beyond is the best time for planting in garden beds. Plant bulbs with one-third to one-half of the bulb above the soil level, ensuring the neck remains exposed. Place bulbs in a location with bright, indirect light, as they prefer moderate sunlight. Water thoroughly after planting, allowing the soil to dry slightly between waterings to prevent rot. During active growth, maintain regular watering and apply a balanced fertiliser every 2-4 weeks. In colder climates, consider planting in pots that can be brought indoors during winter to protect them from frost.
Hippeastrums do not require pruning in the traditional sense like many other plants. However, after the flowers have finished blooming, it’s beneficial to remove the flower stems by cutting them close to the bulb. This helps redirect the plant’s energy back into bulb growth rather than seed production. Additionally, in late spring or early summer, you may trim back any yellowing or dead leaves to tidy up the plant and promote its overall health. This minimal maintenance ensures that the plant remains vigorous and prepares it for the next flowering cycle.
Hippeastrums should be divided every three to five years to ensure they remain healthy and continue to bloom abundantly. Dividing the bulbs helps reduce crowding, improve airflow, and provide each bulb with enough nutrients. The best time to divide hippeastrum is in late summer or early autumn after the foliage has died. When dividing, ensure each section has healthy roots and store the bulbs in a warm place at around 20°C, dusting them with micronised sulphur to protect against fungal infections during storage. When ready, replant in fresh, well-draining soil, ensuring there is ample room for growth.
Hippeastrums can be susceptible to several diseases, including leaf blight (Stagonospora curtisii), which causes brown or black spots with yellow halos on leaves and can lead to foliage yellowing. Bulb rot, often caused by fungi like Fusarium and Rhizoctonia species, manifests as soft, water-soaked spots on bulbs and can lead to bulb decay. Botrytis blight (Botrytis spp.) affects flowers and leaves with greyish mould and lesions, thriving in humid conditions. Basal rot (Rhizoctonia spp.) targets the bulb’s base, causing rot due to overwatering or poor drainage. Though less common, viral diseases can also occur, showing symptoms like mottled or streaked foliage and stunted growth. Managing these diseases involves maintaining good air circulation, avoiding overwatering, and promptly removing infected plant material to minimise spread.
May attract slugs and snails; take preventive measures if necessary.
The bulbs are supplied dormant and should be unpacked promptly and stored in a well-ventilated area to prevent the roots from drying out, even if planting is delayed. If you are delaying planting to time the flowering for a specific occasion, such as potted Christmas gifts, we recommend placing the bulbs in a fridge crisper at around 5 degrees Celsius to slow flower development. DO NOT FREEZE! To ensure Christmas blooms, remove the bulbs from the crisper in mid-November and pot them following the instructions provided.
Caution: Harmful if ingested; may irritate skin and eyes.
