Growing The Sweet Potato Vine

Growing the sweet potato vine is pretty simple. The best time to plant the vine is in the early part of spring or right at the start of summer. Basically, as long as there is not frost danger, then you can expect the Ipomoea batatas to thrive. They are rather sensitive to the cold, so if the ground temperature regularly drops below 45 degrees, chances are they will get damaged or even die off. Any temperature under 55 degrees will hinder proper growth. The best place to plant Ipomoea batatas is in an area that gets plenty of sun and that has soil that drains well. For indoor or potted sweet potato vines, make sure to use well-draining soil that is rich and nutritious.

The best place to plant this colorful vine is in a sunny area that has ample humidity. While they do love heat, dry heat like the desert will cause plant failure. You can house the sweet potato vine indoors if you live in a cooler climate. Simply make sure that you choose a wall that faces south into the sun and that you maintain the proper level of humidity in the room. Patios that face the sun are also ideal since they will absorb enough heat for your vine to thrive. Another great thing about Ipomoea batatas plants used for ground cover is that they are generally deer resistant so you don’t have to worry about your plants being grazed overnight.

Watering The Sweet Potato Vine

Watering the Ipomoea batatas plant is rather simple. They need to maintain a moderate moisture level and once weekly watering should suffice. If your area gets very hot, you can water a bit more, but make sure not to saturate the plant. They should also not be allowed to dry out. You can add water-soluble fertilizer once a month during a watering session if you prefer this method of feeding over slow-release pellets. The sweet potato vine prefers moisture, so if you plan to keep yours indoors an indoor humidifier may be a good idea.

This herbaceous perennial needs well-draining soil to prevent root rot. A pH of 5.5 to 6.5 is ideal for both indoor and outdoor growth. Being that this is a tropical plant, it is a good idea to maintain a general humidity level of at least 60%, though it can survive on less. Mature sweet potato vines are drought-tolerant and can tolerate periodic stretches of low-water, but they will grow abundantly when frequently watered. You can easily tell if your plants are not getting enough water because the leaves will begin to wilt. Simply increase the amount or frequency of your watering sessions to accommodate their need.

Propagating The Sweet Potato Vine

Propagating sweet potato vines is very easy since this fast-growing plant loves to spread its roots. You can take clippings in the early spring, just be very careful with the stems since they are highly fragile. After removing the mother plant from the pot, with a gentle hand loosen the roots. Separate a clump from the main plant and put it aside for your new plant. Replant the mother vine in rich soil. Take your new plant and place it in a hole that is about mid-depth in the soil of the container. Loosely pack down the soil around the base of the plant, but don’t make it too compact. Water the new plant well but make sure that the soil drains completely. When planting in the ground, space your new plants about a half of foot to one foot apart. If you are using a large Ipomoea batatas specimen, then you will need to plant the cuttings at least two feet apart.

The sweet potato vine can be a prolific grower, so make sure to prune it when it becomes too leggy. For plants that are pot bound, you can trim it to help it maintain an attractive shape. All-purpose potting soil is best for indoor plants while outdoor Ipomoea batatas plants can be covered in well-draining compost. When you plant the cuttings, use a slow-release fertilizer for the best results.
