How to Grow Eggplant in Cold / Highland Australia

Soil
Rich, well-drained soil with generous compost and aged manure. Slightly acidic preferred. Heavy feeders.
Salt
Moderately sensitive. Copes with a little salt, but the harvest drops on salty bore water.
pH Range
5.5-6.5
Sunlight
Full sun (minimum 8 hours). More heat-demanding than tomatoes. The warmest, most sheltered position in the garden.
Spacing
60cm apart, 80cm between rows
Watering
Consistent deep watering 2-3 times per week. Irregular watering causes bitter fruit and blossom end rot. Drip irrigation ideal. Avoid wetting foliage.
Good companions
Dwarf Beans, Lettuce, Basil, Marigold, Capsicum
Keep away from
Fennel, Galangal, Guava, Mustard greens (Listed under 'keep apart from' for mustard greens; no reason is given.), Potato, Strawberry (share Verticillium wilt), Walnut (juglone sensitive)
Grow before it
Leafy greens and brassicas (Lettuce, Silverbeet, Broccoli)
Grow after it
Roots and alliums (Carrot, Beetroot, Onion)

Give the bed 3 turns before nightshades go back in. Tomato, capsicum, eggplant and potato share wilts and blights that live on in the soil.

Harvesting Eggplant

When ready: Fruit should be glossy and firm. Press gently. Flesh should spring back. Skin colour at variety-typical stage (deep purple, white, striped etc.). Dull skin and brown seeds inside indicate over-maturity. Fruit will be bitter and seedy.

How to harvest: Cut with sharp secateurs (stems are woody and thorny). Leave 2-3cm of stem. Do not pull. Wear gloves as some varieties have thorns on calyx. Harvest in morning.

Storing and preserving eggplant

How to keep it
  • Freezing (Cooked). Slice eggplant 1cm thick. Grill, roast or pan-fry until soft and golden. Cool completely. Lay on tray to flash-freeze. Transfer to freezer bags. Use in pasta, curry, moussaka from frozen. Do NOT freeze raw. The texture becomes spongy and unpleasant. Keeps: 12 months.
  • Dehydrating. Slice 5mm thick. Optional: lightly salt and stand 20 minutes, pat dry. Arrange on dehydrator trays. Dry at 60C for 8-14 hours until leathery or crispy. Store in airtight jars. Rehydrate in warm water or oil before use. Keeps: 12 months.
  • Baba Ganoush (Freeze). Char whole eggplant over gas flame or under grill until skin is blackened and flesh is completely soft. Peel. Mash with tahini, lemon juice, garlic, salt. Portion and freeze flat in bags. Keeps: 6 months frozen.
  • Pickled (Middle Eastern Style). Slice small eggplants lengthwise. Salt and press 2 hours to remove bitter liquid. Stuff with garlic, walnuts, chilli. Pack into jars. Cover with white vinegar. Seal and process in water bath 15 minutes. Keeps: 12 months.
