However, the plant is also able to tolerate slightly saline soils that are found in coastal areas.
Cultivation of Solanum Erianthum D.Don var. Adulterinum
Solanum erianthum D.Don var. adulterinum (Ham. ex G.Don) Baker & Simmonds, commonly known as "apple of Sodom," is a fruit-bearing plant that requires specific conditions for optimal growth and yield.
When cultivating Solanum erianthum D.Don var. adulterinum, it's important to start with healthy seedlings or saplings purchased from a reputable nursery. The plant prefers well-drained and airy soil that's rich in organic matter. It also requires partial shade, especially during the hottest parts of the day.
Watering Needs for Solanum Erianthum D.Don var. Adulterinum
Solanum erianthum D.Don var. adulterinum requires moderate watering, and it's essential to ensure that the soil doesn't stay soggy. Watering should be reduced during the winter months when the plant enters into dormancy. Overwatering can lead to root rot, which can be detrimental to the plant's growth.
Fertilization of Solanum Erianthum D.Don var. Adulterinum
The "apple of Sodom" plant requires regular fertilization to promote growth and fruiting. A balanced fertilizer with equal parts nitrogen, phosphorus, and potassium should be applied during the growing season (spring and summer) every two to three weeks. Fertilizer application should be reduced during the winter when the plant is dormant.
Pruning of Solanum Erianthum D.Don var. Adulterinum
Pruning is an essential part of Solanum erianthum D.Don var. adulterinum care. It's necessary to remove dead, diseased, or damaged branches to maintain the plant's health and vigor. Additionally, pruning helps to shape the plant and promote growth. The best time to prune is during the winter dormancy, but minor pruning can be done throughout the year.
It's important to wear gloves when pruning the "apple of Sodom" plant since its sap can cause skin irritation and other adverse reactions.
Propagation methods of Solanum erianthum D.Don var. adulterinum (Ham. ex G.Don) Baker & Simmonds
Solanum erianthum D.Don var. adulterinum (Ham. ex G.Don) Baker & Simmonds can be propagated by seeds, cuttings, or layering.
Propagation by seeds
To propagate Solanum erianthum D.Don var. adulterinum (Ham. ex G.Don) Baker & Simmonds by seeds, harvest the fruits when they are ripe and extract the seeds. The seeds must be cleaned and stored in a dry and cool place until planting.
Plant seeds in a well-draining soil mixture and cover them with a thin layer of soil. Water the seeds and keep the soil moist until germination. Germination typically takes 3-4 weeks.
Propagation by cuttings
To propagate Solanum erianthum D.Don var. adulterinum (Ham. ex G.Don) Baker & Simmonds by cuttings, take 8-10 cm long stem cuttings from the mother plant. Remove the leaves from the lower two-thirds of the stem, leaving 2-3 leaves at the top.
Apply rooting hormone on the cut end of the stem and plant it in a well-draining soil mixture. Water the soil and cover the cutting with a plastic bag to increase humidity. Keep the soil moist and remove the plastic bag once the cutting has rooted.
Propagation by layering
To propagate Solanum erianthum D.Don var. adulterinum (Ham. ex G.Don) Baker & Simmonds by layering, select a low-hanging stem that can reach the ground. Make a shallow cut on the underside of the stem and apply rooting hormone on the cut.
Bury the cut portion of the stem in a hole filled with soil, leaving the top of the stem exposed. Water the soil and wait until the layered stem produces roots. Once the roots are established, cut the layered stem from the mother plant and transplant it to a new location.
Disease Management
Solanum erianthum D.Don var. adulterinum is susceptible to several diseases that can affect its growth, yield, and overall health. It is important to take preventive measures to avoid the occurrence of diseases and to apply appropriate management techniques in case disease symptoms appear.
One of the most common diseases affecting Solanum erianthum D.Don var. adulterinum is bacterial wilt, caused by the bacterium Ralstonia solanacearum. Symptoms of bacterial wilt include leaf wilting, yellowing, and browning, followed by plant death. To manage bacterial wilt, it is recommended to use disease-free planting material, rotate crops, and avoid overwatering. Additionally, copper-based fungicides can help to control the spread of the disease.
Another disease that can affect Solanum erianthum D.Don var. adulterinum is verticillium wilt, caused by the fungus Verticillium dahliae. Symptoms of verticillium wilt include yellowing and wilting of the leaves, leading to plant death. To manage verticillium wilt, it is recommended to use disease-free planting material, rotate crops, and avoid overwatering. Additionally, soil fumigation and application of fungicides can help to control the spread of the disease.
Pest Management
Solanum erianthum D.Don var. adulterinum can also be affected by several pests that can cause damage to the plant, reduce yield, and transmit diseases. It is important to take preventive measures to avoid pest infestation and implement management strategies when pests are detected.
One of the most common pests affecting Solanum erianthum D.Don var. adulterinum is the potato tuber moth, Phthorimaea operculella. The larvae of this moth can cause damage to the leaves and tubers of the plant. To manage potato tuber moth, it is recommended to use insecticides and pheromone traps.
Another pest that can affect Solanum erianthum D.Don var. adulterinum is the root-knot nematode, Meloidogyne spp. Symptoms of root-knot nematode infestation include stunted growth, wilting, and yellowing of the leaves. To manage root-knot nematode, it is recommended to use nematode-resistant varieties, rotate crops, and use organic amendments to improve soil health.
Overall, it is important to monitor Solanum erianthum D.Don var. adulterinum regularly for signs of disease and pest infestation and to implement appropriate management strategies to avoid yield loss and ensure plant health.
