Haemanthus prefers temperatures between 18–25°C, making it suitable for indoor cultivation in moderately warm climates. During the winter months, the temperature should be slightly lowered but not fall below 10°C.

Sudden temperature fluctuations can negatively affect the plant's development, especially during the flowering phase. Therefore, it's important to avoid drafts and sharp changes in temperature.

Humidity

Haemanthus is a moisture-loving plant that requires high humidity for proper growth and flowering. The ideal humidity level for Haemanthus is between 60-80%. In dry air conditions, particularly during winter, the plant may experience stress, which can lead to yellowing of the leaves and a reduction in the number of flowers.

To create the appropriate environment, it's recommended to use humidifiers or periodically mist the plant with soft water to maintain the humidity at the necessary level.

Lighting and placement in the room

Haemanthus prefers bright but diffused light. The best location for placing the plant is a window facing east or west, where it will receive enough light but not be exposed to direct sunlight, which can cause leaf burns. Direct sunlight, especially in the summer, can damage Haemanthus' sensitive leaves, so it's essential to protect it from excessive sunlight.

In winter, when the daylight hours shorten, Haemanthus may experience light deficiency. In such conditions, additional artificial lighting, such as grow lights or LEDs, can help extend the light cycle and support the plant's continued growth and flowering. It's also important to ensure that the plant is not exposed to cold drafts, as sudden temperature fluctuations can harm its health.

Soil and substrate

For successful cultivation of Haemanthus, a well-draining, light, and nutrient-rich soil mixture is necessary. The ideal soil mix for this plant should consist of garden soil, peat, sand, and perlite in a 2:1:1:1 ratio. This combination provides good root aeration, preventing root rot, and maintains the required moisture for healthy plant growth. Perlite and sand help improve drainage, which is essential, as stagnant water can cause root decay.

The recommended pH of the soil for Haemanthus should range from 5.5 to 6.5, which is slightly acidic. This level of acidity aids in better nutrient absorption by the plant. To further improve drainage, a layer of expanded clay or fine gravel can be added to the bottom of the pot. This prevents water accumulation in the pot and helps protect the roots from rot.

Watering (summer and winter)

In the summer, Haemanthus requires regular but moderate watering. The soil should remain moist but not overly saturated. Excess moisture can lead to root rot. Watering should be done when the top layer of soil begins to dry. It is important to ensure that excess water does not remain in the saucer or pot, as this can lead to waterlogging. Therefore, pots with good drainage holes are essential.

During winter, watering should be reduced as the plant enters a dormant phase and requires less moisture. The soil should dry slightly between waterings to avoid overwatering. In winter, it is also important to monitor the humidity levels in the room, as dry air can negatively affect the plant’s health.

Fertilization and feeding

Haemanthus should be regularly fertilized during its active growing season, from spring to autumn. Balanced liquid fertilizers with a high phosphorus and potassium content are recommended, as these elements promote blooming and strengthen the plant. Fertilization should be applied every 2–3 weeks, mixed with water for irrigation, to prevent root burns and ensure the plant receives the necessary micronutrients.

In winter, fertilization is not required as the plant is in a dormant phase. Stopping fertilization during this time helps avoid salt buildup in the soil, which can disrupt nutrient absorption. Feeding should resume in spring, when the plant begins its active growth cycle, stimulating new growth and flowering.

Flowering

Haemanthus flowers in spring and summer, depending on environmental conditions. The flowers are arranged in dense, spherical or semi-spherical clusters, which can be white, pink, red, or orange, depending on the species. These flowers have a pleasant fragrance and attract pollinators. Flowering typically lasts several weeks, and with proper care, the plant may bloom multiple times a year.

To ensure continuous and abundant blooming, it is essential to maintain regular watering, good lighting, and timely fertilization. A lack of light or improper care can result in weak flowering or a complete cessation of blooming, so it’s important to create optimal conditions for the plant.

Propagation

Haemanthus can be propagated by both seeds and vegetative methods. Seed propagation requires high humidity and warm conditions. Seeds should be sown in light, moist soil at temperatures between 20–25°C and typically germinate within 2–3 weeks. However, plants grown from seeds may take 2–3 years to bloom, which makes this method less suitable for gardeners seeking faster results.

Vegetative propagation, such as through division or cuttings, is a faster and more reliable method. Cuttings or divisions usually root within 2–3 weeks, and this method allows the new plants to retain the same characteristics as the parent plant. Vegetative propagation is ideal for quickly producing new decorative specimens.

Seasonal features

From spring to autumn, Haemanthus actively grows and blooms, requiring regular watering, fertilization, and good lighting for healthy development. During this period, the plant actively forms new leaves and flower spikes, as well as blooming profusely. Maintaining these conditions will support healthy growth and extend the blooming period.

In winter, Haemanthus enters a dormant phase, and its growth significantly slows down. Water and nutrient needs decrease. It is important to provide stable conditions for the plant to regain energy and accumulate strength for the next growing and blooming season.

Care features

Caring for Haemanthus requires attention to watering, lighting, and temperature conditions. The plant prefers bright but diffused light and cannot tolerate direct sunlight, which can cause leaf burns. It also should be kept away from sharp temperature fluctuations and cold drafts, as these can damage the plant. Maintaining a stable temperature and regularly moisturizing the soil is essential for optimal growth.

It is also important to monitor soil moisture levels, as Haemanthus does not tolerate drought, but it also cannot tolerate water stagnation. Regular inspection of the plant will help identify potential problems with watering or other aspects of care in time.

Care at home

For successful cultivation of Haemanthus indoors, it is necessary to create comfortable conditions. The plant needs bright but diffused light, so it is best to place it on an east- or west-facing window where it will receive sufficient light without exposure to direct sunlight, which can damage its leaves. Direct sunlight, especially in summer, can harm the sensitive leaves of Haemanthus, so protection from excessive sunlight is necessary.

Haemanthus prefers high humidity, so in winter, when heating often reduces indoor humidity levels, it is recommended to use humidifiers or mist the plant regularly. The room temperature should be between 18–25°C, and the plant should be shielded from sudden temperature changes and cold drafts.

Repotting

Haemanthus needs repotting every 1–2 years or when its root system outgrows its current pot. When selecting a new pot, consider its size: the new pot should be 2–3 cm wider in diameter than the root system. It is also important that the pot has a good drainage system, as water stagnation in the container can lead to root rot. Ideally, the pot should be made of plastic or ceramic, as both materials provide good thermal insulation and protect the roots from overheating.

The best time to repot Haemanthus is in spring, before active growth begins. This allows the plant to adapt to new conditions more quickly and minimizes stress. When repotting, carefully remove the plant from its old pot, gently clean the roots from the old soil, and place it in a new pot with fresh, well-drained soil. After repotting, reduce watering slightly to allow the plant time to adjust.

Pruning and crown formation

Haemanthus does not require intensive pruning, but periodic removal of dry and damaged leaves helps maintain the plant’s decorative appeal. Pruning also stimulates the growth of new shoots, which helps improve the overall shape and density of the crown. To form a beautiful and compact crown, you can prune excess old leaves, especially if the plant appears too sparse. This also helps the plant focus its energy on developing younger, healthier parts.

If the plant becomes too tall or its growth becomes excessively long and unruly, more extensive pruning can be performed. Pruning should be done with caution, not removing more than 30% of the plant at once. This will stimulate the growth of lateral shoots and improve its appearance.

Possible problems and solutions

One of the most common problems with Haemanthus is root rot, caused by overwatering or poor drainage. To prevent this, it is important to follow proper watering routines and ensure good drainage in the pot. If root rot occurs, remove the damaged roots carefully and repot the plant into a new pot with fresh soil. It is also important to monitor the condition of the leaves and remove dry or damaged leaves to prevent fungal diseases.

Another problem may be nutrient deficiency, which manifests as yellowing leaves and weak flowering. To resolve this issue, use balanced fertilizers containing phosphorus and potassium, which promote better flowering and overall plant health. It is important to monitor fertilization regularity and avoid overfeeding, as this can also harm the plant.
