Western Australia · Mediterranean/Temperate Climate
A month-by-month planting calendar for Perth gardeners. Perth has a classic Mediterranean climate, hot, dry summers and mild, wet winters, giving it a completely different growing rhythm to the east coast. The long, dry summer (November-April) demands water-wise gardening and heat-hardy varieties, while the cooler months from May to October are Perth's prime growing season. Perth's warm winters mean brassicas, leafy greens, and tomatoes can all produce through the cooler months without frost damage.

Perth's mediterranean/temperate climate means your gardening calendar differs significantly from gardeners in other parts of Australia. With average winter minimums around 9°C and summer maximums reaching 35°C, selecting the right varieties for your conditions is just as important as timing. Focus your energy on March-May (autumn) and August-October (spring), these are your highest-value planting windows when conditions align for strong germination and vigorous growth.
Raised garden beds are particularly well-suited to Perth conditions. They warm faster than ground-level beds in cooler months, drain freely to prevent waterlogging, and allow you to create an ideal growing medium regardless of your native soil type. A depth of 30-40cm gives most vegetables ample root run, while a 1.2m width ensures you can reach the centre from either side without compacting the soil.
Perth's dry summers require consistent irrigation. Raised beds dry out faster than in-ground beds and may need watering every 1-2 days in summer. Installing drip irrigation or soaker hoses on a timer is a worthwhile investment that pays off in reduced time and water use.
With careful planning, Perth gardeners can achieve near year-round harvests from raised beds. The key is succession planting, rather than planting everything at once, sow small batches of fast-growing crops like lettuce, radish, and spinach every 3-4 weeks. This spreads harvests over a much longer window and prevents the frustrating "feast or famine" cycle. The Perth planting calendar above shows exactly when each window opens and closes for your climate.
Perth soils can range from sandy to heavy clay depending on the suburb. For raised beds, start with a 50/50 mix of quality compost and garden loam, adding aged manure and a handful of blood-and-bone per square metre. Mulch heavily with sugar cane or pea straw to protect against summer drying.
For most Perth home gardeners, a 1.2m × 2.4m raised bed at 40cm depth is the ideal starter. It fits a family of 4's core vegetable needs, lets you reach the centre from both sides, and contains enough soil volume to buffer against drying. Use our raised bed calculator to size it for your space.
Well-designed companion combinations reduce pest pressure without chemicals. Plant basil with tomatoes, marigolds along bed edges, and nasturtiums near brassicas. Keep onions away from peas, and never plant tomatoes next to brassicas. See our companion planting guide for the full matrix.
Frost months in Perth: Frost-free (coastal), rare light frosts in hills July-August. Protect frost-tender crops (tomato, basil, beans, zucchini) with a frost cloth, cloche, or cold frame on nights below 4°C. Raised beds warm faster after a cold night than in-ground beds, which means you can remove covers earlier in the morning.
A well-planned 1.2m × 2.4m raised bed in Perth produces around 50-80kg of fresh vegetables per year with succession planting. That covers roughly 30-40% of a family of 4's vegetable consumption, enough to dramatically reduce your supermarket bill. Plant Planner's family calculator does the maths for any bed size.
Perth's mediterranean/temperate climate (winter lows around 9°C, summer highs around 35°C) is well-suited to a wide range of vegetables. The best planting months are March-May (autumn) and August-October (spring). Reliable crops for Perth gardeners include tomatoes, zucchini, beans, lettuce, silverbeet, kale, broccoli, cauliflower, carrots, beetroot, garlic, and herbs like basil and parsley. The month-by-month calendar above shows exactly what to plant when.
In Perth, the most productive planting windows are March-May (autumn) and August-October (spring). Spring plantings (September-November in temperate/cool zones) deliver summer harvests of warm-season crops like tomatoes, beans, and cucumbers. Autumn plantings (March-May) set you up for winter and early-spring harvests of brassicas, leafy greens, peas, and garlic. Frost risk months in Perth: Frost-free (coastal), rare light frosts in hills July-August.
Yes, Perth gardeners can harvest something almost every month of the year with careful planning. The key is succession planting (sowing small batches every 3-4 weeks) and choosing crops that match each season. Raised beds extend the shoulder seasons by warming faster in spring and draining better in wet winter months. Plant Planner generates a 12-month rolling schedule automatically, enter your Perth postcode to get personalised dates.

A 1m × 2m raised bed in Perth can easily feed a family of four across a season with staggered plantings. For example: 4 broccoli + 6 lettuce + 1 row silverbeet + garlic block (winter), rotating to 3 tomato + 6 bean plants + 2 zucchini + herbs (summer). Our raised bed calculator at /raised-bed-calculator does this maths for any bed size.
