Spring in Perth is the prime window for warm-season crops once frost risk passes, tomatoes, beans, zucchini, cucurbits all go in now. The city sits in mediterranean/temperate territory, winter lows around 9°C, summer highs around 35°C, and the spring months (September, October, November) carry a recognisable rhythm that's worth knowing before you plant.
From seed in Perth this spring: Tomato, Cucumber, Zucchini, Beans, Pumpkin, Sweet Corn, Basil, Capsicum, Spring Onion, Okra. That's a long list, which is the upside of Perth's mediterranean/temperate conditions in spring, direct-sowing into raised beds gives you the best germination and the strongest root systems for the season ahead.
As seedlings in Perth this spring: Tomato, Capsicum, Eggplant, Cucumber, Zucchini, Lettuce, Silverbeet, Sweet Potato, Capsicum (heat-tolerant), Pumpkin. Buying seedlings from a local nursery shortens the calendar by 4-8 weeks compared to seed, which matters most in Perth's shoulder windows.
Harvesting in Perth this spring: Broccoli (side shoots), Peas, Broad Beans, Lettuce, Kale, Silverbeet, Leek, Peas (last), Lettuce (last before heat), Radish, Spring Onion, Tomato, Zucchini, Cucumber, Beans, Garlic. The harvest peak runs across the season's middle month, when warm-season crops planted in the previous shoulder are coming into full production.
Perth's dry summers require drip irrigation or soaker hoses rather than overhead watering, conserve water and reduce fungal disease risk simultaneously. Unlike east coast cities, Perth's best tomato planting window is actually August-October for a summer harvest, with a second planting possible in late February. If you want the printable, see the full Perth planting calendar.
Perth's spring suits raised beds for the simple reason that raised beds warm faster than ground-level soil, giving germination a head start and pushing transplants ahead by a week or two, which compounds across a 12-week growing window. The raised bed calculator sizes the bed; the companion planting guide fills it out.
