How to plant
Space your sweet potatoes roughly 12 to 18 inches apart.
In locations where space is at a premium they may be planted as close as 8 inches apart.
Keep in mind they will need more regular watering if planted in a square foot garden style.
Like most plants, Sweet potatoes love compost, fish emulsion, seaweed and other naturally sourced fertilizers.
Over fertilizing may produce lush leafing out at the expense of root size.
As with tomato plants, a sweet potato plant will sprout roots anywhere along its stem. In warm conditions roots grow rapidly
Plant slips with only 1 - 2 leaves above ground as to ensuring as much soil contact with the stem as possible. Even planting at a bit of an angle parallel to the surface rather than deeper.
Water them well in the first couple weeks after planting to encourage them to grow and establish healthy root systems that will carry them through extreme heat.
