The Natal plum can be grown indoors, especially in regions where the winter temperatures drop below its preferred range of 50-65 degrees Fahrenheit. By bringing the plant indoors, you can provide it with a controlled environment that meets its temperature requirements.
Growing the Natal plum indoors does require some attention to ensure its well-being. Since it prefers day temperatures of 68 degrees or higher, it is important to place the plant in a location where it can receive sufficient sunlight. Ideally, a south-facing window or a spot with bright, indirect light would be suitable for the plant’s growth. However, if natural light is not sufficient, you can also use artificial grow lights to supplement the light requirements.
One challenge when growing Natal plum indoors is maintaining the right humidity levels. The plant prefers a moderately humid environment, but high humidity can increase the risk of fungal infestations. To mitigate this, it is advisable to use a nearby fan to improve air circulation around the plant. The fan helps to reduce excess moisture on the foliage and prevents the growth of fungi. Additionally, placing a tray filled with water near the plant can also help increase humidity levels without creating a damp environment.
When it comes to watering, it is crucial to strike a balance. Overwatering can lead to root rot, while underwatering can cause stress to the plant. It is best to water the Natal plum when the top inch of soil feels dry to the touch. Use room temperature water and ensure that the pot has drainage holes to allow excess water to escape. During the winter months, when the plant is in its dormant phase, watering should be reduced.
In terms of fertilization, the Natal plum benefits from regular feeding during the growing season. A balanced, water-soluble fertilizer can be applied every 2-4 weeks, following the instructions on the fertilizer packaging. However, it is important not to over-fertilize, as this can lead to salt build-up in the soil, which can harm the plant.
Pruning is also an important aspect of Natal plum care. Regular pruning helps maintain the plant’s shape and encourages bushier growth. It is best to prune the plant in early spring before the growing season begins. Remove any dead, damaged, or overgrown branches, and shape the plant as desired. Be sure to use clean, sharp pruning shears to avoid tearing or injuring the plant.
With proper care and attention to its temperature, light, humidity, watering, fertilization, and pruning needs, the Natal plum can thrive indoors. It may require a bit more effort compared to growing it in its natural outdoor environment, but the beauty and fragrance of the plant make it a worthwhile addition to any indoor garden.
