Indian Nightshade
Indian nightshade (Solanum torvum) is a slow-growing evergreen shrub native to the tropical climates of the Indian subcontinent. It’s a bushy shrub and can reach up to 6 yards in height with a spread of around 3 yards wide. Indian nightshade has thick, glossy leaves and clusters of tiny white flowers. Its fruits can range in color from yellow to purple or red and they have a pleasantly sweet flavor when ripe. It’s a versatile plant that makes an excellent indoor houseplant or a great addition to a backyard garden. This plant is easy to care for and is known for its very waxy looking foliage.
Indian nightshade needs regular watering, but avoid overwatering as this causes root rot. Make sure the pot has good drainage and water it thoroughly whenever the soil is dry 1 inch below the surface. It’s best to reduce watering during the winter and check the soil to make sure it’s never waterlogged.
Indian nightshade can tolerate a wide range of light levels, although it does best in bright, indirect sunlight. In a typical indoor environment, medium to bright indirect sunlight will be enough and it should be placed near an open window with plenty of natural light. If the light is too low, you may eventually notice yellowing of the leaves. Too much direct sunlight can cause sunburn on the leaves, so be sure to avoid that.
Indian nightshade prefers temperatures between 60-75°F (15-24°C). This makes it ideal for an indoor environment with enough light and proper care. If the temperature starts to get too low, there is an increased risk of plant diseases like root rot. If the temperature is too high, it can cause the leaves to scorch.
Humidity levels should be kept between 40-60% for very best health. Low humidity causes leaves to dry out and can also increase the risk of disease. If the humidity is too low, you can try using a humidifier or simply misting the leaves. It’s also a good idea to keep your Indian nightshade away from direct drafts of cold air.
Indian nightshade prefers a well-draining soil with a slightly acidic to neutral pH. A cactus or succulent mix would be a good option, or you can mix your own with a combination of coarse potting soil, sand, and perlite. If you are mixing your own, it’s best to test the pH of the soil mixture first and add a bit of lime if the pH is too low.
Fertilizing your Indian nightshade is not necessary, but you can feed it with a balanced fertilizer that is formulated for houseplants. Be sure to dilute it to half strength and only fertilize during the growing season (spring through summer). Too much fertilizer can burn the roots and leaves, so use sparingly and follow the directions on the packaging.
Indian nightshade is susceptible to a few common pests, such as mealybugs, aphids, spider mites, and scale insects. Mealybugs and aphids tend to be most troublesome, appearing as tiny white clusters or a white, cottony material on the stems and leaves. Spider mites appear as tiny red or green spots that can cause the leaves to yellow and drop. Scale insects tend to form waxy, disc-shaped bumps on the leaves and stem of the plant. The best way to get rid of any of these pests is to use an insecticidal soap or a neem oil solution. Make sure to carefully inspect your plant frequently for any signs of these pests.
Indian nightshade needs to be repotted every 2-3 years, as its roots can become too bound in an insufficiently sized pot. Spring or early summer are the best times to do this. When repotting, use a basic potting mix with perlite or pumice added for better drainage. Make sure the new pot has plenty of drainage holes at the bottom.
Indian nightshade does not require any pruning, although you can trim any dead or damaged branches as needed. It’s best to avoid pruning during the hotter months as new growth is likely to get scorched with direct sunlight. If you do need to prune, make sure to use sterilized scissors or pruners to avoid the spread of disease from one plant to another.
The best mulch for Indian nightshade is a light, organic mulch such as compost or wood chips. This will help retain moisture and cut down on weeds. Avoid using very thick mulch layers around the base of the plant as this can cut off air circulation and cause root rot.
Indian nightshade can be propagated from both seed and cuttings. To propagate from seed, simply sow the seeds in a sterile potting mix and keep them at a temperature of 70-80°F (21-27°C) in bright, indirect light. Keep the soil moist but not soggy and the seeds should germinate in 10-14 days. To propagate from cuttings, take 4-5 inch cuttings and remove the lower leaves. Dip the lower end of the cutting in rooting hormone and plant in a sterile potting mix. Keep it in bright, indirect light and mist regularly to keep the soil moist. Roots should start to appear in 3-4 weeks.
Indian nightshade does not require any support, but if it gets too tall you can use a stake or bamboo pole to provide extra stability. This plant can also be used as a climber on a fence or wall.
Indian nightshade does not require a rest period and will continue to grow year-round as long as it’s kept in the proper temperature range. You may choose to prune back foliage if needed during the cooler months of the year.
Indian nightshade is considered toxic to cats, dogs, and other pets if ingested. The leaves contain saponins that are toxic to animals and care should be taken to keep it out of reach when grown indoors.
