Winter squash

Cucurbita maxima

Belonging to the Cucurbita genus, Winter squash has a botanical name of Cucurbita maxima.

Pumpkins grow on a spreading vine which may be trained to spread over a trellis or the roof of a building (shed, veranda). Generally they are grown at ground level where they may spread anywhere between a 1metre and 5 metres, depending on the variety.

It is an edible vegetable / fruit and is treated mainly as an annual, so it grows best over the course of a single year. Normally growing to a mature height of 50.0 cm (1.62 feet), Winter squash grows with a vinelike habit. This plant tends to bloom in early summer, followed by first harvests in late summer.

Mexico is believed to be where Winter squash originates from.

Due to how easy it is to grow in a variety of conditions, Winter squash is great for beginner gardeners and those that like low maintainance gardens.

How to grow Winter squash

  • Full Sun

    +
  • Medium

In some circumstances fruit may rot and fall off before gaining any size, small losses are not necessarily a concern. If this problem persists then it may be attributed to a lack of pollination which can be remedied by hand pollinating. In the early morning, take a male flower (generally on a long stalk, no fruiting body present) and apply it to the female flower (small bulb or fruiting body, at the base of the flower) so as to transfer pollen from male to female, thus mimicking the action of pollinating insects.

Water the plant by dripper or applying water directly at soil level (soaker hose, etc.), no splashing, misting or spraying foliage. Do this sometime between sunrise and before sundown, to allow humidity levels around the plant to stabilise and reduce fungi disease problems.

Powdery mildew may become a problem if humidity becomes too high – try a weekly spraying of a water and milk solution (1 part milk: 9 parts water) over the leaves at the first signs of mildew.

Position in a full sun location and remember to water moderately. Use Zone 10 - Zone 12 as your guideline for the appropriate climate for this plant. A soil ph of between 6.1 and 7.5 is ideal for Winter squash as it does best in weakly acidic soil - weakly alkaline soil. Keep in mind when planting that Winter squash is thought of as tender, so remember to ensure that temperatures are mild before moving outdoors.

Growing Winter squash from seed

Seed will generally sprout with no assistance, however if the seed coating has not naturally cracked, light scarifying with sand paper may be used if germination issues occur.

Aim to sow 1.17 inches (3.0 cm) deep and try to ensure a gap of at least 2.27 feet (70.0 cm). Soil temperature should be kept higher than 21°C / 70°F to ensure good germination.
