How to Grow Tomato in Cool Temperate Australia
- Soil
- Well-drained, rich loam with plenty of compost. Deep soil preferred. pH-adjusted with lime if acidic.
- Salt
- Moderately sensitive. Copes with a little salt, but the harvest drops on salty bore water.
- pH Range
- 6.0-7.0
- Sunlight
- Full sun (minimum 6-8 hours daily). More sun = more fruit = more flavour.
- Spacing
- 60cm apart, 90cm between rows
- Watering
- Deep watering 2-3 times per week, consistent and at the base. NEVER overhead water, promotes fungal disease. Inconsistent watering is the #1 cause of blossom end rot and fruit splitting. Drip irrigation is ideal.
- Good companions
- Nasturtium, Carrot, Radish, Basil, Chives
- Keep away from
- Broccoli, Cabbage, Chickpeas, Chinese cabbage, Collards, Dill (attracts tomato hornworm), Fennel, Galangal, Kale, Kohlrabi, Mustard greens (Listed under 'keep apart from' for mustard greens; no reason is given.), Peach, Pear, Popcorn (Listed as a bad companion for corn.), Potato (shared diseases), Raspberry (share diseases), Strawberry, Sweet Corn (shared corn earworm), 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.
