Growing butternut squash at home or on the allotment is easy, given a sunny spot and a rich, free-draining soil. Plenty of compost and horse manure should be added to the soil when preparing the planting area.

Being large and flat, butternut squash seeds are easy to work with, and make good sowing projects for children.
For the earliest crops, sow indoors from late April. Sow individually in small pots filled with multi-purpose compost. Yoghurt pots are a good alternative. Sow the seeds about 1 inch deep on their sides. Place pots in a propagator or clear plastic bag and set on a warm windowsill until seeds germinate. At this point, remove covers but keep in the warmth.
Young butternut squash plants are easy to handle thanks to large foliage and thick stems, but treat them delicately as you transfer them to the garden or allotment. Harden them off for a week or so, after all danger of frosts and plant out.
Alternatively, sow outdoors in May in soil that has been pre-warmed with a cloche. Sow two seeds per station and thin to the strongest seedling if both seeds germinate.
Trailing varieties are best left for the vegetable patch. For success in pots, choose compact bush varieties such as Barbara. Use the largest pot you can, aiming for a minimum of 45cm (18in) diameter and just as deep. Two plants should perform well in a grow bag. Set in a spot and water regularly to prevent compost from drying out. Do away with frequent feeding through the season by adding incredicrop® to your compost at planting time. With 7 months coverage it will last the life of these long season plants.
As plants begin to sprawl and grow into each other it can be hard to locate the centre of the plant for watering. Set a cane by each plant when planting out to act as a marker later in the season.
Double up on space by growing butternut squash around the base of sweetcorn plants.
