Sweet Potatoes in Old Struan

Place slips in trays of moist compost at 3rd April - 17th April and keep them warm and bright. Pot them on once roots show and shoots are growing strongly.

Move each rooted slip into a small pot once the roots fill the starter compost. Keep the compost just moist and give them plenty of light so they do not go leggy.

Acclimatise the plants gradually for 12th June - 26th June by moving them outside for longer each day. Keep them under fleece or in a cold frame at night if temperatures dip.

Set the plants in their final position once the soil is warm and all frost risk has passed. Space them 30–45 cm apart, water in thoroughly straight away, and use cloches or fleece early on if nights are cool.

As growth spreads from 23rd July, tuck stray stems back into the row and keep weeds down around the plants. Avoid heavy feeding, as that pushes foliage rather than tubers.

Lift a sample tuber from 22nd September once the plants have had enough warm growing time. Harvest the main crop through 29th October before frost damages the foliage, and handle the tubers carefully because their skins bruise easily.
