Planting Essentials

Butternut squash is easy to grow. Below we address some common queries:

  • Hardiness: this species is half-hardy and must be protected from frost.
  • Planting In Pots: suitable for growing in pots 45cm (18in) deep or larger.
  • Position: place in full sun for best results.
  • Soil Types: sow in fertile, well-drained soil.

Germination Requirements: place seeds in a propagator or clear plastic bag; alternatively sow outdoors in May in soil that has been pre-warmed with a cloche.

Planting Distance (Seed Tray): sow seeds 2.5cm (1in) deep in small pots, or around 2.5cm (1in) apart.

Planting Distance (Ground): make planting pockets 90cm (3ft) apart, and sow 2-3 seeds 2.5cm (1in) deep.

Soil Preparation: remove weeds and large stones, dig in compost or horse manure.

Thinning: if more than one seed has germinated per hole, thin out the weaker one.

Pest Control: protect from birds and insects using row covers or copper rings.

Watering Requirements: water regularly, particularly during dry periods.

Seeds Jargon

  • F1 Hybrids: hybrid seeds are produced from two specially selected varieties that are kept in isolation. As they are produced from only two plants, seeds are almost identical genetically.
  • Open Pollinated: open pollinated plants aren't isolated from other varieties, so are more genetically diverse.
  • Heirloom: heirloom seeds are historic, some going back to Victorian times, others more recent. Heirloom varieties can be good or bad, depending on how careful the breeder is to maintain genetic similarity.
Hybrids vs Open Pollinated

As hybrids are produced from two specially selected varieties, the quality is more consistent, with a higher germination rate and improved cropping. But, as they require time, resources and know-how to create, they come to the market at a higher cost. They are also genetically unstable, and so if you keep the seeds from the resultant crop, performance is usually poor. Open Pollinated seeds are highly diverse and have often been grown for successfully for decades. Seeds from the resultant crop are usually perform well.

Annual, Biennial and Perennial

Annual plants complete their life cycle within a year, biennials in two years (usually only flowering in the second year) and perennials can live on indefinitely.

Hardy, Half-Hardy and Tender

Hardy and half-hardy plants can survive a light frost, but the latter are best moved indoors during periods of bad weather. Tender plants must be kept indoors, until after the last frost.

We believe that anyone, regardless of ability can successfully grow their own plants at home, and do so in an eco-friendly and sustainable way.
