Light Requirements
Nestlera biennis generally prefers part shade to full shade conditions. When grown in full sun, the plant may struggle to survive and is susceptible to sunburn. As such, it is recommended to grow Nestlera biennis in locations that receive filtered light or partial shade.
Temperature Requirements
The optimal temperature range for Nestlera biennis growth is between 24 - 28 °C. The plant does not tolerate frost or extreme fluctuations in temperature and will not survive in freezing conditions. The minimum temperature that the plant can tolerate is 16 °C. It is important to keep the plant in a warm environment with adequate humidity.
Soil Requirements
Nestlera biennis prefers well-draining soils with a pH range of 6.5 to 7.5. The soil should be rich in organic matter, moisture-retentive, and able to provide adequate aeration to the plant's roots. The plant does not grow well in water-logged soil and can easily develop root rot if the soil is not well-draining. A soil mixture of peat moss, sand, and perlite can be used to create a suitable growing environment for Nestlera biennis.
Cultivation Methods
Nestlera biennis, commonly known as the Giant Crinum Lily, is a lovely ornamental plant found in tropical forests. To cultivate this plant, you need to ensure it gets a bright, partially shaded location. If planting in a pot, use a deep pot that accommodates the plant's long roots and provides enough space for the bulb to grow.
For outdoor planting, dig a hole and place the bulb around 30 cm deep in well-draining soil that has been enriched with compost. The plant should be positioned upright and covered with soil. After planting, water the area generously and avoid allowing the soil to dry out during the establishment phase
Watering Needs
Nestlera biennis needs regular watering, especially during the growing season. You should ensure that the soil is always moist; however, do not overwater as this can lead to bulb rot. Check the soil's moisture level regularly by inserting your finger into the soil, and if it feels dry, water the plant.
During the dormant season, lower the watering frequency but do not let the soil dry out completely because this may damage the bulb. Alternatively, you can store the bulb in a dry and cool location and gradually re-introduce water when the season approaches.
Fertilization
Fertilization is necessary to obtain healthy and robust N. biennis bulbs. When planting or repotting, gradually mix compost and slow-release fertilizer into the soil
You can also fertilize this plant once the growing season commences. Use a balanced NPK (Nitrogen, Phosphorus, Potassium) fertilizer and apply it every 3-4 weeks until fall. Over-fertilizing can burn the plant's roots, and thus, it is crucial to follow the recommended instructions on the fertilizer packaging.
Pruning
Pruning is not necessary for N. biennis. However, you can remove old, yellow or damaged leaves to promote better growth for the younger leaves. Cut flower stalks after the blooms have faded.
Trimming the leaves can cause plant stress, and it should be avoided unless necessary. Additionally, avoid cutting the bulb's neck, which absorbs water and nutrients to sustain the entire plant.
Propagation of Nestlera biennis (Jacq.) Spreng.
Nestlera biennis (Jacq.) Spreng. or commonly known as "macaranga" is a native plant of Southeast Asia. It belongs to the family Euphorbiaceae and is often used in traditional medicine. There are several ways to propagate this plant:
Seed propagation
One of the easiest ways to propagate Nestlera biennis is through seeds. The ideal time to collect seeds is when the fruit starts to turn brown. Collect the fruit and let it dry for a few days. Once the fruit is dry, remove the seeds and sow them immediately. The soil should be moist, well-draining with a pH of 6-7. Place the pot in a shaded area and keep the soil moist until germination.
Cuttings
Another way to propagate Nestlera biennis is through stem cuttings. Take a 6-8 inch stem from the mother plant and strip the lower leaves. Dip the cut end in rooting hormone powder and plant it in a pot filled with well-draining soil. Place the pot in a shaded area and keep the soil moist. After a few weeks, the cutting will start to grow roots and new leaves.
Air layering
Air layering is another method to propagate Nestlera biennis. Take a healthy stem from the mother plant and make a small cut in the middle of the stem. Insert a toothpick to keep the cut open and wrap damp sphagnum moss around the cut. Then, wrap it with plastic to keep it moist. After a few weeks, roots will start to grow from the moss. Cut the stem below the roots and plant it in a pot with well-draining soil.
Division
Division is a method that can be used if the mother plant is large enough. Carefully remove the plant from its pot and divide it into smaller parts. Ensure that each part has roots and leaves and plant them into separate pots. Water the plants thoroughly and place them in a shaded area until new growth starts.
Disease Management
Nestlera biennis (Jacq.) Spreng. is susceptible to various fungal and bacterial diseases. Here are some common diseases that can affect this plant:
- Leaf Spot: It is caused by fungi like Cercospora and Phyllosticta. Symptoms include small, circular, brown or black spots on the leaves. To manage leaf spot, remove infected plant material and avoid overhead watering. Fungicidal sprays containing copper or chlorothalonil can be used.
- Anthracnose: This disease is caused by fungi like Colletotrichum and Glomerella. It can cause wilting, yellowing, and necrosis of leaves and stems. To manage anthracnose, remove infected plant material and avoid overhead watering. Fungicidal sprays containing copper or chlorothalonil can be used.
- Botrytis Blight: It is caused by the fungus Botrytis cinerea and affects flowers and foliage. Symptoms include gray-colored, fuzzy mold on leaves and flowers. To manage Botrytis blight, remove infected plant material and avoid overhead watering. Apply a fungicidal spray containing thiophanate-methyl or chlorothalonil.
Pest Management
Nestlera biennis (Jacq.) Spreng. can also be susceptible to various insect pests. Here are some common pests that can affect this plant:
- Aphids: They are soft-bodied insects that suck sap from the leaves, causing curling and yellowing of leaves. To manage aphids, spray the plant with insecticidal soap or neem oil.
- Spider Mites: They are tiny pests that can cause discoloration and stippling on the leaves. To manage spider mites, wash the leaves with water to remove the pests. Apply insecticidal soap or neem oil regularly.
- Thrips: They are tiny insects that feed on the leaves, causing distortion and silvering of leaves. To manage thrips, remove all weeds and debris around the plant. Apply insecticidal soap or neem oil regularly.
