Sweet potato vine – plant care

When growing ornamental sweet potato vines, it’s essential to water the plants – especially during the first stage of their development. When your potato vine develops tuberous roots, it means it can accumulate water, and is more likely to survive hot days. In practice, you have to water the plants every day, and when they develop tubers, you can limit watering to once per week.

The soil should be moist all the time, but only slightly. Both excess and insufficient amounts of water are dangerous to the plant.

Sweet potato vine grows quite fast and, therefore, it needs a lot of nutrients. Before planting it in a particular spot, make sure to enrich the soil using a slow-release fertilizer. During the vegetation period, dilute fertilizer designed for balcony plants and water the plant with it every 2-3 weeks.
