This is a list of steps to show how to grow butternut squash.
1. Sow Butternut Squash seed indoors in April, so they have a long enough growing season.
- Plant 1 seed in a small pot , point bit facing up.
- Cover with some clingfilm and put on a frost-free window sill.
- Temperature needs to be above 60F for germination.
- Remove the cling film when they emerge (takes 1 or 2 weeks)
- They will be ready to plant out 4 weeks after planting or when they have 3 leaves.
- Don’t rush because squash like warm soil and will be killed by frost.
- Introduce them to outside conditions gradually, by putting the pots outside during the day for a bit, so they harden off.
Plant the butternut squash out:
- when the soil has warmed up & all risk of frost has gone.
- plant in a sheltered spot, out of cold winds.
- protect with a cloche or cold frame if possible.
- dig a bucket sized hole, & fill it with soil mixed with compost or well rotted farmyard manure
- plant the butternut squash in the soil mixture
- the butternut squash plants should be at least 1m apart
- mulch the soil with compost or well rotted farmyard manure.
- watch out for slugs – they will eat the shoot off if given a chance
Growing the butternut squash:
- feed the plants once a week
- water regularly – they will drink a lot
- keep the plants under glass or plastic, if possible, unless the sun is very hot
Ripening the butternut squash:
- the squash will start to ripen in September
- remove any leaves covering the fruit so the sun can reach them
- leave the squash on the plant to ripen, unless the days get cold. Do not leave on the plant if frost is forecast
- when the fruit has turned yellow it is ripe
- cut the squash off the plant with a knife, leaving a short 5cm stalk
- leave the butternut squash on a sunny windowsill to dry out and ripen, for 2 weeks, before putting into store
Storing butternut squash:
- allow the fruit to dry completely before storing
- store in a cool, dark, airy place
