Growing Eggplant in Western Australia

Introducing Eggplant

Eggplants are known by many names and various varieties have been cultivated in vast regions of the globe. They come in a variety of shapes and sizes and are attractive bushes which make a stunning addition to any vegetable garden. They love the heat, so they thrive in the Western Australian summers and are reasonably drought tolerant. Plant them in a sunny spot and they’ll reward you with an abundant harvest all summer long.

Classic Mistakes

Eggplants need their space. If you follow square foot gardening or companion planting methods, be sure to give them enough space to grow. They don’t want to be shaded or have to compete for nutrients.

Sunlight

Grow in: Full Sun

Soil Preparation

Eggplants are heavy feeders. Be sure to work some compost and well-rotted manure into your soil before planting. Remember not to plant where tomatoes, peppers, eggplants or potatoes have grown the previous year.

Sowing Seed

Sow seed: August-December
Sowing depth: 5 - 10 mm

Soak seeds in water overnight.

Eggplants need really warm soil to germinate. You can start them in the garden once the soil is warm, but its easiest to start them indoors, preferably on a heat mat. Simply cover the seeds with soil and keep them warm and moist. If you want to get a head start on the growing season, then its quicker and easier to plant seedlings.

Planting

Plant seedlings: September-January

Plant seedlings at least 50cm apart and stake for support. The bushes can grow quite large and they need a bit of extra support to protect them in windy weather. Stakes or cages are both good options for support. It’s also a good idea to add some bonemeal to your planting holes. They like the extra calcium in the bonemeal and it helps them to produce a strong root system.

Care

Pinch out the growing tips for a bushier plant and limit fruits to 5 or 6 per plant for better a size and quality of fruit.

Watering

The hot, dry Western Australian summers cause the ground to dry out very quickly. Make sure your eggplants get watered regularly, but don’t let the soil get soggy or water logged. They can handle the soil drying out, but will really struggle in waterlogged soil.

Feeding

If your soil was well prepared, then your eggplants shouldn’t need feeding again until the flowers appear. As soon as they start to flower, give them a low-nitrogen feed to encourage flowers and fruit. Compost tea, a balanced organic fertilizer or a tomato fertilizer are all good options. Feed every 3 or 4 weeks through the fruiting season.

Mulching

A thick layer of organic mulch helps to stop water from evaporating in the hot, dry, Victorian summers. Lucerne, pea straw or sugarcane are all great, organic options. The mulch will break down and add organic matter to your soil over time, so keep topping it up throughout the growing the season.

Harvesting

Harvest: 10 to 15 Weeks After Planting

You can pick the fruit at any stage, depending on your requirements. As soon as the fruits reach the size you would like, use a sharp knife or secateurs to cut the fruit from the plant. The fruits should be firm and glossy. If they start looking dull, they’re past their best. They can still be eaten, but will be slightly more bitter and spongy.

What to Plant Now

What to do about Bacterial Wilt?

Can be caused from growing eggplants in a spot where tomatoes or potatoes grew in the previous year. There is no cure but the best way to avoid it is crop rotation.

What to do about Powdery Mildew?

Milk spray or baking soda solution work well and can be sprayed on affected plants.
