Cucurbita spp.
Sow after frost in spring; in tropical areas sow all year. Pumpkins need a good-sized area, grow them on a fence if space is limited. Sow seed 2.5 cm deep, directly into hills of compost, 1 metre apart, into warm soil. Pinching out the growing tip or leader on a pumpkin plant will divert energy and nutrients to the lateral growth or side branches. This stops the vine from sprawling and taking over your garden; it also encourages fruit formation. When the plant is about 1.5 metres long, pinch 2 cm off the very end. The growth tip or apical meristem is the site of growth hormone production; removing the tip stops suppression of the lateral branches' growth. This results in a less sprawling plant with more fruit. Incorporate plenty of well-rotted animal manure before planting. Harvest Pumpkins when fully coloured and the stem is brown. Pick with a stem 6 cm long and dry in the sun before storing.

The Three Sisters Garden
This is a traditional Native American planting method using an inter-crop of corn, beans and squash. This vegetable guild sustained the Native Americans both physically and spiritually. In legend, the plants were a gift from the gods, always to be grown together, eaten together and celebrated together. Each of the sisters contributes something to the planting. Together, the sisters provide a balanced diet from a single planting. As older sisters often do, the corn offers the beans needed support and are planted first. The beans, the giving sister, add nitrogen to the soil for the benefit of all three. The large leaves of the squash vines protect the threesome by creating living mulch that shades the soil, keeping it cool and moist and preventing weeds. In this case it needs to be a running squash, not a bush squash like zucchini. In North American the term 'summer squash' is used for zucchini and button squash that are thin-skinned and do not store well; 'winter squash' is used to describe pumpkins and thicker-skinned squash like 'Delicata' or 'Vegetable Spaghetti'. Good choices are smaller leafed and smaller vines of Butternut Cucurbita moschata, 'Delicata' or 'Vegetable Spaghetti' Cucurbita pepo rather than the biggest pumpkins Cucurbita maxima like 'Queensland Blue' and 'Australian Butter'. Together, the three sisters provide both sustainable soil fertility as well as a healthy diet.

Q. Why don't my pumpkin, squash or zucchini set fruit?
A. The most obvious problem can be lack of bees. Many gardeners find they need to hand pollinate. To encourage a visit by bees, avoid using overhead sprinklers and any form of insecticide. Bees also do not like windy conditions.

There are a range of other factors that influence pollination and successful fruit set:
  • too much rich nitrogen fertiliser will cause leaf growth at the expense of flowering,
  • too high a summer temperature will do the same,
  • being stung by Cucumber fruit fly can cause tiny fruit to drop off the vine,
  • moisture stress will do the same, and
  • lack of calcium or boron will also cause young fruit to yellow and drop off.
At Green Harvest we are passionate about open-pollinated, heirloom seed as we believe it is a resource belonging to all people, not a product to be exploited by a few. Open-pollinated vegetable seeds are genetically diverse treasures that have been passed on from generation to generation of gardeners.
