How to Grow Eggplant in Mediterranean 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.
