Fabricia plicata Thunb. requires bright, indirect light to thrive. It can be grown outdoors in partial shade or in a location that receives morning sun and afternoon shade. If grown indoors, it should be placed near a window that receives filtered or indirect light. Direct sunlight can cause the leaves to burn.
Temperature Requirements
Fabricia plicata Thunb. prefers warm temperatures between 18°C to 27°C (64°F to 81°F). It can tolerate temperatures slightly outside of this range, but extreme temperatures should be avoided. If grown outdoors, it should be protected from frost, as it cannot survive temperatures below 4°C (40°F).
Soil Requirements
Fabricia plicata Thunb. grows best in well-draining soil that is rich in organic matter. It prefers soil that is slightly acidic with a pH between 5.5 to 6.5. The soil should be watered regularly to keep it evenly moist, but not waterlogged. Overwatering can lead to root rot, which can be fatal to the plant.
Cultivation of Fabricia plicata Thunb.
Fabricia plicata Thunb., also known as the Japanese jewelweed, is a beautiful plant that can be cultivated in gardens or indoor pots.
The plant thrives in a moist and well-draining soil with a pH level of about 6 to 7.5. Ensure that the soil is rich in organic matter.
Plant the seeds or seedlings in bright but indirect sunlight or partial shade. It is advisable to transplant or move the plant to a warm, sheltered spot in winter.
Watering requirements
The Japanese jewelweed requires regular watering, especially during the hot and dry season. Water the plant once a week, and ensure that the soil is continually moist.
However, avoid over-watering the plant as it can lead to root rot. Water it only when the top inch of the soil is dry. You can also mist the leaves to increase the humidity around the plant.
Fertilization
To promote healthy growth, fertilize Fabricia plicata Thunb. with a balanced fertilizer, rich in nitrogen, phosphorus, and potassium, every two weeks during the growing season. Avoid over-fertilizing the plant as it can lead to disease and pest infestation.
Pruning
Pruning Fabricia plicata Thunb. is not mandatory, but it can help to shape the plant, promote bushiness, and improve its appearance. Prune the plant in early spring when it is coming out of dormancy.
Cut back any dead or damaged stems, and reduce the size of the plant by up to one-third. Prune the plant just above a node or leaf to prevent dieback.
Propagation of Fabricia plicata Thunb.
Fabricia plicata Thunb. is a perennial herbaceous plant that belongs to the family Scrophulariaceae. It is also known as folded dragonhead, and it is native to Japan, Korea, and China. Propagation of Fabricia plicata Thunb. can be done through various methods such as seed, division, and cutting.
Propagation by Seed
The propagation of Fabricia plicata Thunb. by seed is straightforward and does not require any special treatment. The seeds can be collected from the plant when they are fully mature, and the pods start to dry. After collecting the seeds, they should be stored in a cool and dry place until the next season's planting begins.
The best time to plant the seeds is in late winter or early spring, approximately six to eight weeks before the last frost. The seeds should be sown in trays or pots containing well-draining soil, and they should be covered with a thin layer of soil. The trays or pots should be placed in an area with bright, indirect light and kept moist until the seedlings emerge.
Propagation by Division
Propagation of Fabricia plicata Thunb. by division is an easy and practical method, and it is best done during the plant's dormant period in early spring or autumn. The plant should be carefully dug out of the ground, and the root system should be gently divided into smaller sections.
Each section should contain at least one healthy shoot and a portion of the root system. The sections should then be planted immediately in well-draining soil, and they should be kept moist until they are established.
Propagation by Cutting
Fabricia plicata Thunb. can also be propagated by stem cuttings. This method is best done during the plant's active growing season in late spring or early summer.
The stem cuttings should be taken from healthy and disease-free plants, and they should be approximately six inches long. The leaves on the lower half of the cutting should be removed, and the cutting should be dipped in rooting hormone before being planted in a well-draining soil mixture.
The cuttings should be watered regularly and kept in an area with bright, indirect light until they develop roots and start to grow. Once they are established, the cuttings can be transplanted into their permanent location in the garden.

Powdery mildew: Powdery mildew is a fungal disease that affects the leaves of the plant, causing a white powdery substance to form on them. To manage this disease, remove the affected leaves and dispose of them properly. Ensure that the plant has adequate air circulation and avoid overwatering. Apply a fungicide to the remaining leaves as a preventative measure.
Common Pests
Spider mites: Spider mites are common pests that prefer dry conditions. They are small and difficult to see but they cause yellowing and leaf drop in the plant. To manage this pest, wash the plant with high-pressure water to remove them. Apply insecticidal soap or neem oil to the remaining plant as a preventative measure.
Scale insects: Scale insects are small, oval-shaped pests that attach themselves to the leaves and stems of the plant, sucking out the plant's sap. They cause yellowing of the plant's leaves and can be difficult to remove. To manage this pest, remove the affected plant and dispose of it properly. Apply an insecticidal soap or neem oil to the remaining plant as a preventative measure.
Thrips: Thrips are small, slender insects that can damage the plant's leaves and flowers. They cause distortion and discoloration of the plant's leaves and flowers.
