Butternut Squashes in Barr's Cottage

Sow seeds on their edge around 28th March - 4th April, about 2 cm deep in small pots. Keep them at 18–21 °C and do not sow too early, as seedlings go root-bound quickly in poor light.

Move seedlings on once they have their first true leaves, from 14th April. Handle them by the leaves, not the stem, and keep them growing on in bright light so they do not become lanky.

Gradually acclimatise plants around 4th April - 2nd May. Put them outside for a few hours at a time, then bring them back in if cold nights return, until they are ready for planting out.

Set plants into rich soil or a compost-enriched mound from 2nd May once frost risk has passed. Water them in thoroughly straight after planting, then give each plant plenty of room to run.

From 5th May, keep the young growth well watered and protect it with fleece or a cloche if nights turn cold. Lift developing fruit onto dry boards or tiles so they do not sit on damp soil and rot.

From 5th May to 29th September, water deeply at the base whenever the soil starts to dry. Feed every 14 days with a high-potash fertiliser once fruits begin to swell, and keep the leaves dry to limit mildew.

Harvest from 8th September to 6th October when the skin is hard, the colour is full, and the stalk is starting to cork. Cut each squash with a short stalk attached, then cure the fruits in the sun for 10-14 days to harden the skin for storage.
