Description
Zucchini is one of those plants that grow prolifically in the garden, producing an abundant crop when conditions are right. There are dozens of varieties of zucchini to choose from with a wide range of colours and shapes, from round to crookneck and cylindrical. Both the flower and the fruit are edible and can be used in both sweet and savoury dishes – a must have in every summer veggie patch.
Growing conditions
Like most summer squash, pumpkins, melons and other sprawling vine plants, zucchini prefers well- drained soil rich in compost or aged manure. Plant in full sun, applying a monthly application of liquid fertiliser, particularly when fruits start to grow. Mulch well to retain moisture and water regularly at the base of the plant to avoid wetting the leaves, as this can increase chances of fungal problems. The plant will produce both male (short stems) and female flower (longer stems with small zucchini fruit) which require pollination. Insects and bees will pollinate flowers; however they can also be hand pollinated with a small brush by gently brushing the pollen from the male flower to the centre of the female flower.
Sowing Zucchini Seeds
The seeds are quick to germinate and should be sown in Spring and Summer approximately 2-3cm deep and 50-90cm apart. Whilst not necessary, however if growing in a small space, zucchini can be trained on a small trellis or stake to minimise sprawling.
Harvesting and Using Zucchini
When conditions are favourable, zucchini can be harvested as early as 7-10 weeks. To harvest, use sharp snips or secateurs to cut the stem approximately 2-3cm from the fruit to not damage the vine or any other fruit that may be growing. Pick when the fruit is young (15-20cm). Zucchini can be used in both sweet or savoury dishes such as zucchini bread, spiralled into noodles, roasted, added to fritters, or preserved in a relish. The flowers are also a delicacy and can be roasted, added to salads, or stuffed, however removing flowers may impact pollination of further fruit development.
