The Adenostemma viscosum J.R. & G. Forst. plant requires full sun or partial shade to grow well. It needs to be exposed to sunlight for at least 6 hours a day. Insufficient light causes slow growth, reduced flowering, and excessive foliage growth.
Temperature Requirements
The Adenostemma viscosum J.R. & G. Forst. plant thrives well in tropical and subtropical regions with warm to hot temperatures. It prefers temperatures between 20 and 30 degrees Celsius (68-86 degrees Fahrenheit). Cold temperatures and frost can harm the plant.
Soil Requirements
The Adenostemma viscosum J.R. & G. Forst. plant prefers well-drained and fertile soils rich in organic matter. The soil pH should range from acidic to slightly alkaline (5.0-7.5). Sandy loam soil with good drainage is ideal for the plant. Wet soils with poor drainage should be avoided as they can cause root rot.
Watering Requirements
The Adenostemma viscosum J.R. & G. Forst. plant requires regular watering during the growing season. It should be watered deeply at least once a week. The soil should be evenly moist, but not waterlogged. Overwatering can cause the roots to rot. Watering should be reduced in winter when the plant is dormant.
Fertilizer Requirements
The Adenostemma viscosum J.R. & G. Forst. plant requires periodic fertilization to promote growth and flowering. A balanced fertilizer with N-P-K ratio 10-10-10 or 20-20-20 is suitable. Fertilizing should be done during the growing season, about once a month. Overfertilizing can lead to excessive growth and reduced flowering.
Cultivation methods
Adenostemma viscosum J.R. & G. Forst. is a perennial plant that thrives in tropical and subtropical climates. It grows well in well-drained soils with a pH range of 5.5 to 6.5. The plant requires a lot of sunlight and can tolerate high temperatures.
Propagation can be done through stem cuttings at the beginning of the rainy season. The cuttings should be planted in a well-prepared nursery bed to sprout. After about 6 to 8 weeks, the seedlings can be transplanted to their permanent position.
Watering needs
Adenostemma viscosum J.R. & G. Forst. requires regular watering, especially during the hot and dry seasons. The plant should be watered deeply once or twice a week. Overwatering should be avoided as it can lead to root rot.
The soil should be kept evenly moist but not waterlogged. It is essential to monitor the moisture levels in the soil and adjust the watering schedule accordingly.
Fertilization
Fertilization should be done during the planting stage and regularly thereafter. Adenostemma viscosum J.R. & G. Forst. requires a balanced fertilizer with an NPK ratio of 4:2:1 or 3:1:2. Organic fertilizers such as compost and manure can also be used.
The fertilizer should be applied in a ring around the plant's base at the beginning of the rainy season and during flowering and fruiting. Care should be taken not to over-fertilize as this can lead to the burning of roots and leaves.
Pruning
Pruning should be done at the end of the dry season to remove dead or diseased branches and promote new growth. This will also help to maintain the plant's shape and improve its overall health.
When pruning, it is essential to use clean and sharp tools to avoid injuring the plant. Any tools used for pruning should be disinfected with alcohol or a bleach solution to prevent the spread of diseases.
Propagation of Adenostemma viscosum J.R. & G. Forst.
Adenostemma viscosum J.R. & G. Forst., commonly known as sticky snow white, is a perennial plant that belongs to the Asteraceae family. The plant is native to Southeast Asia and tropical regions of Australia.
The propagation of Adenostemma viscosum J.R. & G. Forst. can be done by seeds, cuttings, and division.
Propagation by seeds
The propagation of Adenostemma viscosum J.R. & G. Forst. by seeds requires proper collection, cleaning, and storage. The seeds should be collected from mature, healthy plants and dried in the shade. The dried seeds can be stored in airtight containers at room temperature for up to six months. Before sowing, the seeds can be soaked in water for 12 hours to improve germination rate. The seeds can be sown directly in the soil or in seed trays filled with a well-draining potting mix. The soil should be kept moist but not waterlogged.
Propagation by cuttings
The propagation of Adenostemma viscosum J.R. & G. Forst. by cuttings involves taking stem cuttings from mature plants. The stem cuttings should be about 15 cm long and should have a few leaves attached. The lower leaves should be removed, and the stem should be dipped in a rooting hormone powder. The cuttings can be planted in a well-draining potting mix and kept in a warm, humid place. The soil should be kept moist, and the cuttings should develop roots in about four to six weeks.
Propagation by division
The propagation of Adenostemma viscosum J.R. & G. Forst. by division involves dividing the root ball of a mature plant into smaller sections. This method can be used to rejuvenate an old plant or to create new plants. The plant should be carefully dug up, and the root ball should be divided into smaller sections using a sharp knife or garden tool. Each section should have a few stems and roots. The sections can be planted in a well-draining potting mix and kept in a warm, humid place until new growth appears.
Disease and Pest Management for Adenostemma viscosum J.R. & G. Forst.
Adenostemma viscosum J.R. & G. Forst. is a plant that is susceptible to various diseases and pests. Below are some common issues that may affect the plant and ways to manage them effectively:
