Although it does not have significant economic or medicinal uses, it is grown as an ornamental in some parts of the world and has cultural significance in some traditional practices and rituals.
Light Requirements
The plant Schizaea robusta Baker prefers to grow under shady conditions. Direct exposure to sunlight can damage the leaves, and in some cases, it can stunt the growth of the plant. Partial shade or filtered light is ideal for this plant species. In natural conditions, the plant grows under tree canopies or in shaded areas of the forest floor. If you are growing the plant indoors, place it near a window that receives indirect sunlight or use artificial grow lights.
Temperature Requirements
The optimal temperature range for the growth of Schizaea robusta Baker is between 16°C to 24°C. The plant can tolerate temperatures as low as 8°C and as high as 30°C, but it will grow slower under these conditions. It is essential to maintain a stable temperature around the plant to create an optimal growth environment. Extreme fluctuations in temperature can stress the plant and inhibit its growth. In colder regions, you can grow the plant indoors or in a greenhouse to regulate the temperature and humidity levels.
Soil Requirements
Schizaea robusta Baker prefers well-draining soil that is rich in organic matter. The ideal soil pH for this plant species is between 5.5 to 7.5. The plant can tolerate a wide range of soil types, including sandy, loamy, and clay soils. However, the soil should not be waterlogged as the plant can suffer from root rot. You can add peat moss, compost, or other organic matter to the soil to improve its water-holding capacity and nutrient content. The plant does not require frequent fertilization, but you can add a slow-release fertilizer occasionally to promote its growth.
Cultivation methods
Schizaea robusta Baker, commonly referred to as the hard shield-fern, is a terrestrial, xerophytic fern. It is native to the coastal regions of South Africa, and it grows in well-drained sandy soils.
The plant prefers a semi-shaded or shaded location. Direct sunlight could damage the fronds. It grows well in temperatures between 20°C to 25°C but could tolerate temperatures as high as 30°C.
Schizaea robusta Baker requires soil with a pH of 6.0-7.5 for optimal growth. The soil should be moist, but not waterlogged.
Watering needs
The hard shield-fern is a drought-resistant plant that can go for weeks without water. It, however, requires regular watering, especially during the summer, to keep the soil consistently moist.
Avoid saturating the soil with water as it could lead to root rot. Always ensure to water the plant in the morning or late afternoon, preferably when the sun is not too hot, to prevent evaporation.
Fertilization
Schizaea robusta Baker is not a heavy feeder, and excessive fertilization could lead to the accumulation of salts in the soil, which is detrimental to the plant's health.
During the growing season, fertilize the plant with a balanced fertilizer, preferably every 2-3 weeks. Limit the use of nitrogen-rich fertilizers as it could result in lush foliage but weak stems.
Pruning
Pruning Schizaea robusta Baker is not necessary as it has a compact growth habit. However, it is advisable to remove any yellowing or damaged fronds as it could attract pests and diseases.
When pruning, use sterile pruners, and ensure to clean them after use.
Propagation of Schizaea robusta Baker
Schizaea robusta Baker is a fern species that can be propagated through spores and division methods.
Spore Propagation
Spore propagation is the easiest way to propagate Schizaea robusta Baker. The spores are easily obtained by collecting mature fronds that have sori. The collected fronds are dried and the spores are extracted. Once extracted, the spores are cleaned and sown onto a seed bed that has a mixture of sphagnum moss and sterile soil. The seed bed is then kept moist and in a shaded area. Once the spores germinate, the young plants are transplanted after a year or two, depending on their growth rate, to individual pots or an outdoors area with well-draining soil.
Division Propagation
Division propagation is another common method of propagating Schizaea robusta Baker. This method involves taking an established clump of the fern species and dividing it into smaller pieces. Each divided clump should have some roots and fronds. The divided pieces can then be potted or planted in well-draining soil. The timing for the division method is best during the plant's dormant period.
Propagation of Schizaea robusta Baker through spores or division can be an easy way to propagate new plants, provided that the propagator has the necessary knowledge, equipment, and patience to succeed.
Disease and Pest Management for Schizaea robusta Baker
Schizaea robusta Baker, commonly known as umbrella fern, belongs to the family Schizaeaceae. Like any other plants, it is vulnerable to diseases and pest infestations. Here are the common diseases and pests that might affect Schizaea robusta Baker and ways to manage them:
Diseases
1. Fungal diseases: Schizaea robusta Baker is susceptible to different kinds of fungal infections. The most common fungal diseases that affect the plant are Rhizoctonia solani, Phytophthora parasitica, and Fusarium oxysporum. Fungal infections can cause wilting of the leaves, yellowing of the foliage, and stunted growth. To manage fungal diseases, remove the infected parts of the plant and dispose of them properly. Take care not to overwater the plant, and avoid splashing water on the foliage. You can also apply fungicides as a preventive measure.
2. Viral diseases: Schizaea robusta Baker can also be affected by viral infections, such as Tomato spotted wilt virus (TSWV). Viruses are usually transmitted by pests like thrips and aphids. Once infected, the plant may show symptoms like yellowing, stunted growth, and deformed leaves. Unfortunately, there is no cure for viral diseases. Hence, you need to remove and destroy infected plants to prevent the spread of the virus. You can also use insecticides to control the pests that transmit the virus.
Pests
1. Spider mites: Spider mites are tiny pests that suck the sap from the leaves of Schizaea robusta Baker. Infested leaves will have discolored spots and may look dusty. To manage spider mites, you can use insecticidal soap or neem oil. You can also try spraying the plant with water to dislodge the mites.
2. Scale insects: Scale insects are small, immobile pests that feed on the plant's sap. They appear as small, waxy bumps on the leaves and stems. To manage scale insects, you can use insecticidal soap or neem oil. You can also remove the scales manually using a cotton swab dipped in alcohol.
3. Mealybugs: Mealybugs are soft-bodied insects that feed on the plant's sap, causing stunted growth and yellowing of the foliage. They also secrete a sticky residue that attracts ants. To manage mealybugs, you can use insecticidal soap or neem oil. You can also remove them manually using a cotton swab dipped in alcohol.
Overall, preventing diseases and pests from affecting Schizaea robusta Baker requires proper care and maintenance. Make sure that the plant is planted in well-draining soil, receives adequate light and water, and is regularly fertilized. Keeping the plant healthy and strong will make it less vulnerable to diseases and pests.
