The size of gazania depends on the species and growing conditions. In the open ground, gazania can grow up to 30 cm tall and spread up to 45 cm wide, creating dense, ornamental carpets. In containers, it typically remains compact, not exceeding 20 cm in height.

The size of the plant also depends on the availability of suitable growth conditions. In greenhouses or with proper lighting, gazania can grow faster and form denser clumps with more vibrant flowers.

Growth rate

Gazania has a moderate growth rate. Under good care and optimal conditions, it can grow up to 5 cm per month during the active growing season, which usually lasts from spring to autumn. Flowering begins within two to three months after planting and can last until autumn.

However, in conditions of insufficient light or water, the growth of the plant slows down, and it may not reach its maximum height or size. To maintain vigorous growth and blooming, it is important to provide the plant with adequate light, water, and nutrients.

Lifespan

Gazania is a perennial plant that can live for 3-4 years with proper care. In some cases, it may live longer, especially in greenhouse conditions where the climate is stable. However, in colder climates or under improper care, the lifespan of gazania may be limited.

With age, gazania may begin to lose its ornamental value, especially if it does not receive enough nutrients or light. To prolong the life of the plant, it is important to provide regular care and repotting.

Temperature

Gazania prefers warm climates and grows best at temperatures between 18 and 30°C. The plant is sensitive to frost, and temperatures below 5°C can cause damage or even death. Gazania also does not tolerate sudden temperature fluctuations, so it is important to maintain a stable temperature and avoid cold drafts.

In winter, if grown indoors, the temperature should not drop below 10°C to preserve the health of the plant and allow it to continue developing.

Humidity

Gazania tolerates low humidity well, which makes it an ideal plant for dry, sunny areas. It is not particularly demanding on humidity levels, but for optimal growth, it is best to maintain humidity around 40–60%. Excessive moisture can lead to root rot, so it is important to avoid overwatering.

During winter, when heating may lower indoor humidity, using a humidifier or occasionally misting the leaves with soft water is recommended. High humidity can lead to fungal diseases, so it is crucial to monitor humidity levels to prevent waterlogging.

Lighting and placement in the room

Gazania prefers bright but diffused light. It grows well in areas with direct sunlight, but not too much exposure, as this can cause sunburns on the leaves. The best places for gazania are east- or west-facing windows where it can get enough light without being overheated.

In winter, when the daylight hours are shorter, gazania may require additional lighting.

Soil and substrate

For optimal growth, Gazania requires well-drained, nutrient-rich soil. The ideal soil mixture for Gazania consists of garden soil, peat, sand, and perlite in a ratio of 2:1:1:1. This combination provides good aeration for the roots, preventing root rot, while retaining enough moisture for normal plant growth. Perlite and sand help improve drainage, which is important because standing water in the soil can cause root decay.

For Gazania, it is recommended to maintain the soil pH within the range of 5.5–6.5, which corresponds to slightly acidic conditions. This acidity helps the plant absorb nutrients efficiently. To enhance drainage and ensure adequate aeration, adding a layer of expanded clay or small gravel at the bottom of the pot is advisable. This will prevent water accumulation in the container and protect the roots from rot.

Watering (summer and winter)

In the summer, Gazania requires regular but moderate watering. The soil should be moist but not overly saturated with water to prevent root rot. Water the plant when the top layer of soil begins to dry out, but ensure that excess water does not remain in the pot or saucer. Therefore, it is essential to use pots with good drainage holes so that excess moisture can escape.

In 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 over-watering. This is particularly important because excess water in winter can lead to fungal diseases and root rot.

Fertilization and feeding

Gazania requires regular feeding during its active growth period, from spring to autumn. Balanced liquid fertilizers with high phosphorus and potassium content are recommended, as these elements promote flowering and strengthen the plant. Fertilization should be applied every 2–3 weeks, diluted in watering water to avoid root burns and ensure the plant receives all the necessary micronutrients.

In winter, fertilizers are not needed as the plant is in its resting phase. Stopping the feeding during this period helps prevent the accumulation of salts in the soil, which can interfere with nutrient uptake. Fertilization resumes in spring when active growth begins, which helps stimulate flowering and recovery.

Flowering

Gazania begins to bloom during the warmer months, typically from late spring to early autumn. The flowers of the plant can be various shades—from yellow and orange to red, pink, and even purple. The flowers often have contrasting stripes or spots, making them especially attractive. The blooming period can last for several weeks, and under optimal conditions, it can repeat several times per year.

For prolonged and abundant flowering, it is important to maintain regular watering, good lighting, and timely fertilization. Lack of light or improper care can result in weak blooming or complete cessation of flowering.

Propagation

Gazania can be propagated by both seeds and vegetatively. Seed propagation is a slower process that requires high humidity and warmth. 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 usually do not flower for 2–3 years, which makes this method less desirable for gardeners seeking immediate blooms.

Vegetative propagation by cuttings is a faster and more reliable method. Healthy shoots are selected and rooted in a mixture of sand and perlite. Cuttings generally root within 2–3 weeks, and this method ensures that the offspring retain the characteristics of the parent plant. Vegetative propagation is an excellent way to quickly produce new decorative specimens.

Seasonal features

From spring to autumn, Gazania grows and blooms actively, requiring regular watering, fertilization, and good lighting. During this period, the plant continues to develop, producing new leaves and flower spikes. Maintaining these conditions ensures healthy growth and prolonged flowering.

In winter, Gazania enters a dormant phase, and its growth slows down. The need for water and nutrients decreases significantly. It is important to provide stable conditions so the plant can store energy for the next growth and flowering cycle in the coming season.

Care features

Caring for Gazania requires regular attention, especially with regard to watering and lighting. The plant prefers bright, diffused light and should be kept away from direct sunlight, which can cause leaf burns. Additionally, it is important to maintain a stable temperature and protect the plant from cold drafts to ensure optimal growing conditions.

Particular attention should be given to watering—Gazania does not tolerate over-watering, so it is important to ensure that no water remains in the saucer. Regularly inspecting the plant helps identify any problems early on and adjust care accordingly.

Care at home

For successful growth of Gazania indoors, several key factors need to be maintained. The plant prefers bright but diffused light, so it is best placed on a window facing east or west. Direct sunlight can cause leaf burns, so protection from it is essential, especially during the summer months.

Gazania requires moderate humidity, which is particularly important in winter when indoor heating can reduce humidity levels. It is recommended to use humidifiers or regularly mist the leaves with soft water. The room temperature should be between 18–25°C, and it is important to avoid sharp temperature fluctuations to avoid damaging the plant.

Repotting

Gazania should be repotted every 2–3 years or when its root system outgrows the pot. When selecting a new pot, its diameter should be 2–3 cm larger than the previous one to allow the roots to develop freely. The pot should have a good drainage system to prevent water stagnation, which could cause root rot.

The best time to repot Gazania is in the spring before the active growth period begins. When repotting, carefully remove the plant from its old pot, ensuring not to damage the roots, and transplant it into fresh soil with good drainage. After repotting, reduce watering slightly to allow the plant time to adjust.

Pruning and crown formation

Pruning Gazania is necessary to maintain its compact shape and encourage the growth of new shoots. Removing dead or damaged parts helps maintain its ornamental value and prevents disease buildup. Regular pruning also encourages more abundant flowering by stimulating side shoot growth.

If the plant becomes too sparse or leggy, a more extensive pruning can be performed by cutting the stems back by 10 cm from the base. This will improve the plant's density, stimulate its growth, and ensure more intense flowering.

Potential problems and solutions

One of the main problems Gazania owners face is root rot, often caused by over-watering or poor drainage. To prevent this, it is essential to monitor watering patterns, ensure good drainage, and avoid leaving water in the saucer. In cases of root rot, damaged parts should be carefully removed, and the plant should be repotted into a new pot with quality drainage.

Nutrient deficiency can also become an issue, especially if the plant is not flowering or its leaves are yellowing. In such cases, it is important to start regular feeding with a balanced fertilizer containing essential micronutrients, such as phosphorus and potassium.
