Keep in mind when planting that Carolina Ruby is thought of as tender, so it is really important to plant out well after your last frost date. Ideally plant in loamy, sandy and silty soil and try to keep the ph of your soil between the range of 6.1 and 7.8 as Carolina Ruby likes to be in weakly acidic soil to weakly alkaline soil.
Sow at a depth of approx.
3.9 inches (10.0 cm) and aim for a distance of at least
1.46 feet (45.0 cm) between Sweet Potato plants.
By our calculations, you should look at sowing Carolina Ruby about 20 days after your last frost date.
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Carolina Ruby is a tender plant.
