The Sweet Potato Plant: A Complete Guide and Care Tips
When it comes to gardening, sweet potato plants are a great choice. Not only do they produce delicious tubers that can be used in a variety of dishes, but they also have lovely foliage that can add visual interest to your garden. However, growing sweet potatoes isn’t always easy. Here’s everything you need to know about planting and caring for these versatile plants.
Choosing the Right Location
- Sweet potatoes require full sun; choose an area with at least six hours of sunlight per day.
- The soil should be well-draining and rich in organic matter.
- A pH between 5.0 and 6.5 is ideal for sweet potatoes.
- Avoid planting sweet potatoes in areas where other members of the Nightshade family (such as tomatoes) have grown recently as this could lead to pest infestations.
Planting Sweet Potatoes
- In most areas, you’ll want to plant your slips (baby sweet potato plants) after the last frost date has passed.
- To create your own slips from a mature sweet potato, place it in water until roots begin to grow; then cut off the sprouts and plant them outside or in pots indoors until warmer weather arrives.
Caring For Your Plants
- Sweet potatoes require regular watering but avoid overwatering which could lead to rotting tubers or fungal diseases.
- Fertilize sparingly with low-nitrogen fertilizer throughout the growing season.
- Weed regularly around your plants so that their roots aren’t competing with other vegetation for nutrients.
Pests and Diseases
- Slugs and other pests can be discouraged by using organic repellents or diatomaceous earth.
- Sweet potatoes are susceptible to several fungal diseases, including black rot. To prevent these diseases, keep your plants well-ventilated and avoid overwatering them. If you do notice signs of disease, remove infected plants immediately to prevent the fungus from spreading.
Harvesting Sweet Potatoes
It typically takes between 100-140 days for sweet potato vines to mature enough for harvest. The leaves will begin to yellow at this point, indicating that it’s time to start digging up your tubers.
- Dig carefully around each plant with a garden fork or trowel so as not to damage the tubers.
- Cure harvested sweet potatoes by keeping them in a warm (85°F), humid environment for about two weeks before storing them in cool (55°F) conditions where they can last up to six months.
In Conclusion
Growing sweet potato plants is both challenging and rewarding. With the right care and attention, you can have a bountiful harvest that will last well into the winter months.
If you’re looking for an easy-to-grow crop that yields delicious results, then give sweet potatoes a try this season!
