How to grow sweet potatoes
Sweet potatoes are grown from plant cuttings called ‘slips’ This can be produced either from older plants or by inducing the tubers to sprout by keeping them covered by moist sand or making it stand in water with its 90% above water for a few days.
Once the slips are hardened they can be transferred to a prepared bed or a large pot which is stuffed with well composted farm yard manure and wood ash or leaf mould and vermin compost. While it grows allow it to root in as many nodes as possible as they all will turn into tubers. These rarely flower and may have seeds too but it is of no value in re-growing as the slips are always used in growing this.
If planting on a prepared raised bed plant each slip 12 inches apart and that will soon grow and cover the bed. When the vines mature and older leaves turn yellow, stop watering, preferably 3-4 weeks, before harvesting. This will allow the tubers to form well and grow in size.
Pests: This is a hardy plant which needs no much care but some insect pests like the golden tortoise beetle attack the leaves and eat off the leaves.
Harvesting sweet potatoes
The pots can be emptied and the tubers separated. If in raised beds, the sides can be dug.
