Light Requirements
Aulacocalyx jasminiflora Hook.f. var. brevis N.Hallé requires bright, indirect light to thrive. Too much direct sunlight can scorch the leaves, and too little light can lead to weak growth and poor flowering. Ideal indoor locations for these plants include east- or west-facing windows where it can receive bright light but not direct sun exposure.
Temperature Requirements
The ideal temperature range for Aulacocalyx jasminiflora var. brevis is between 65 to 75 degrees Fahrenheit during the day, dropping 10 degrees at night. In general, they cannot tolerate temperatures below 50 degrees Fahrenheit or sudden temperature changes, which can cause leaf drop and shock the plant. Therefore, keep them away from drafty areas and air conditioning vents. In addition, they prefer high humidity, so it might benefit from a pebble tray or a humidifier nearby.
Soil Requirements
Aulacocalyx jasminiflora var. brevis thrive in well-draining soil that is rich in organic matter. A soil pH of around 6 to 6.5 is ideal. The soil must be kept moist, but not waterlogged, as overly wet soil can promote root rot and other diseases. To improve soil drainage, you can add perlite, vermiculite, or sand. During the growing season, feed the plant every two weeks with a balanced liquid fertilizer to promote healthy growth and flowering.
Cultivation Methods
Aulacocalyx jasminiflora Hook.f. var. brevis N.Hallé is a shade-loving plant that prefers a humid environment. It can be grown in pots or in a shady part of the garden with well-draining soil, enriched with organic matter. To propagate this plant, stem cuttings should be taken from healthy, mature plants during the growing season, and rooted in a suitable rooting medium. Once rooted, the cuttings can be planted in pots or in the garden.
Watering Needs
Aulacocalyx jasminiflora Hook.f. var. brevis N.Hallé requires consistent moisture to thrive. Water the plant regularly, keeping the soil in the pot or garden bed evenly moist. It is important not to overwater the plant as it can lead to root rot. During the winter months, reduce watering but do not allow the soil to dry out completely.
Fertilization
The Aulacocalyx jasminiflora Hook.f. var. brevis N.Hallé plant requires regular feeding for vigorous growth and flowering. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium, available in slow-release granules or liquid form. Apply the fertilizer every two weeks during the growing season, and reduce feeding during dormancy in the winter months.
Pruning
Aulacocalyx jasminiflora Hook.f. var. brevis N.Hallé does not require heavy pruning, except to remove damaged or dead parts of the plant. Pinch off any faded blooms to encourage new growth and prolong the flowering period. Regularly remove any yellowing or dried leaves to prevent any diseases and maintain the plant's appearance.
Propagation of Aulacocalyx jasminiflora Hook.f. var. brevis N.Hallé
Aulacocalyx jasminiflora Hook.f. var. brevis N.Hallé, commonly known as 'Siam Tulip', is a rhizomatous perennial plant found in Southeast Asia. It produces attractive, trumpet-shaped pink or white flowers. The plant can be propagated through various methods, including:
Division
Division is the most common method of propagation for Aulacocalyx jasminiflora Hook.f. var. brevis N.Hallé. In this method, the plant is dug up and divided into sections, with each section containing a piece of the rhizome and several shoots. Division is best done in spring before the plant begins to grow again.
Seeds
The plant can also be propagated by seeds, which are small and black. However, Aulacocalyx jasminiflora Hook.f. var. brevis N.Hallé is not commonly grown from seed as it can take up to 10 years for the plant to flower from seed. If using seeds for propagation, sow them in a well-draining soil mix and maintain a warm and moist environment until germination.
Cuttings
Aulacocalyx jasminiflora Hook.f. var. brevis N.Hallé can be propagated from stem cuttings, but the success rate is low. Use cuttings that have at least one node and several leaves. Dip the cuttings in a rooting hormone and plant them in a well-draining soil mix. Maintain high humidity around the cuttings until roots form.
