All About Sweet Potato Vine
Sweet potato vines are a member of the Ipomoea family and are native to tropical regions around the world.
They are primarily grown for their ornamental value, although sweet potato vines can also be used for culinary purposes.
Sweet potato vines come in a variety of colors, including green, purple, and variegated, and can be grown in both indoor and outdoor settings.
When To Plant Sweet Potato Vine
Sweet potato vines are a warm-weather crop and should be planted after the danger of frost has passed.
In most regions, this will be in late spring or early summer. If you are planting sweet potato vines indoors, you can do so at any time of the year.
Sweet Potato Vine Care
Light & Temperature
Sweet potato vines are tropical plants that require bright light to grow well. In general, they prefer full sun to partial shade, although some varieties can tolerate more shade than others. If you are growing your sweet potato vine indoors, place it near a sunny window or under a grow light.
If you are growing it outside, be sure to choose a spot that receives at least six hours of direct sunlight each day. In terms of temperature, sweet potato vines prefer warm temperatures between 70-80°F (21-27°C).
They can tolerate slightly cooler temperatures, but anything below 50°F (10°C) can cause damage to the plant. If you are growing your sweet potato vine indoors, be sure to keep it away from drafty windows or doors.

Water & Humidity
Sweet potato vines require consistent moisture to grow well, but they do not like to be waterlogged. Water your plant deeply once a week or when the top inch of soil feels dry to the touch.
When you water, be sure to water the soil, not the leaves, to prevent fungal diseases. If you are growing your sweet potato vine in a container, be sure to use a well-draining potting mix to prevent waterlogging.
In terms of humidity, sweet potato vines prefer moderate to high humidity levels between 50-70%. If the air in your home or growing space is dry, you can increase humidity by misting the leaves with a spray bottle or placing a humidifier nearby.

Soil
Sweet potato vines prefer well-draining soil that is rich in organic matter. If you are growing your plant in a container, be sure to use a high-quality potting mix that is specifically designed for container gardening.
If you are planting your sweet potato vine in the ground, amend the soil with compost or well-rotted manure to improve drainage and fertility.

Fertilizer
Sweet potato vines are heavy feeders and require regular fertilization to grow well. Use a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium.
You can fertilize your plant every two weeks during the growing season or use a slow-release fertilizer once a month. Be sure to follow the manufacturer's instructions for application rates.

Repotting
Sweet potato vines grow quickly and can quickly outgrow their containers. If you notice that your plant is becoming root-bound, it may be time to repot it.
Choose a container that is one size larger than its current container and use fresh potting mix. Be sure to water your plant well after repotting to help it adjust to its new container.
Propagation
Sweet potato vines are easy to propagate from stem cuttings. To propagate your plant, take a stem cutting that is 4-6 inches long and remove the leaves from the bottom 2-3 inches.
Dip the cut end in rooting hormone and plant it in a container filled with moist potting mix. Place the container in a warm, bright location and keep the soil moist until the cutting has rooted.

Frequently Asked Questions
Why are my sweet potato vines dying?
There can be several reasons why your sweet potato vines are dying, including overwatering, underwatering, lack of sunlight, pests, or diseases.
To troubleshoot the problem, check the soil moisture level, the amount of sunlight the plant is receiving, and inspect the plant for any signs of pest infestation or disease.
Adjust the watering schedule, move the plant to a brighter location if necessary, and treat any pest or disease issues promptly. If the plant does not recover, it may be best to remove it and start fresh with a new plant.
What causes sweet potato vines to turn yellow?
Sweet potato vines may turn yellow due to a variety of reasons, such as overwatering, underwatering, poor soil quality, nutrient deficiency, or pests. Overwatering or poor drainage can lead to root rot, causing the plant to turn yellow.
Underwatering, on the other hand, can cause the leaves to wilt and turn yellow. A lack of nutrients, especially nitrogen, can also cause the leaves to yellow. Pests such as spider mites or whiteflies can also cause yellowing.
To address yellowing sweet potato vines, check the soil moisture level, adjust watering accordingly, ensure the plant is getting adequate nutrients, and treat any pest issues promptly.
Can sweet potato vines survive the cold?
Sweet potato vines are tropical plants and are not frost tolerant. They are sensitive to cold temperatures and can suffer damage or die when exposed to temperatures below 50°F (10°C).
If you live in a region with cold winters, it is best to grow sweet potato vines as annuals or as indoor plants during the winter months.
