Planting Sweet Potato Plants
Sweet potato plants are heat-loving, low-maintenance garden vegetables. They have a vining growth habit and the plants establish quickly. They enjoy full sun (at least 6-8 hours during the growing season) and thrive in loose, well-drained, nutrient-rich soils – although they will tolerate almost any planting site.
NOTE: This is part 3 in a series of 8 articles. For a complete background on how to grow sweet potato plants, we recommend starting from the beginning.
When to Plant Sweet Potato Plants
The best time to plant sweet potato plants is after the ground is thawed and after the last spring frost date has passed. If the ground doesn’t freeze in your location, then the best time to plant is usually a month after your last spring frost date.
Planting Location for Sweet Potato Plants
Sweet potatoes enjoy full sun (at least 6-8 hours during the growing season) and thrive in loose, well-drained, nutrient-rich soils – although they will tolerate almost any planting site.
Soil Preparation for Sweet Potato Plants
Sweet potatoes grow well in nutrient-rich soil, so prepare the sunny, well-drained planting site with compost or well-aged manure prior to planting. If your soil has water-retention issues, you may need to amend with coir, or Coco-Fiber Potting Medium. If your soil is compact or composed of heavy clay, it is recommended that you build raised beds or large mounds of top soil (amended if needed) to plant and grow sweet potatoes. Building up 10-12 inches above the native soil should work fine.
Proper Spacing for Sweet Potato Plants
Space planting holes at least 12 inches apart and space planting rows about 36 inches apart. This allows space for vigorous vines to grow and avoids light or nutrient competition, while also giving you room to move easily through your planting site to mulch, water, and eventually harvest.
