Classic four seasons with warm summers and cool winters. Occasional light frosts inland.
October falls in spring for most of Australia, but in temperate zones this means typical seasonal shifts that guide what crops perform best. The recommendations below are calibrated specifically for temperate conditions with local rainfall patterns, temperature ranges, and frost dates in mind.
Direct or in punnets
These crops perform best when direct-seeded or started in seed trays in October for temperate conditions.
Transplant-ready
These crops establish faster from nursery seedlings in October. Harden off for 3-5 days before planting out.
From earlier plantings
Crops typically ready for harvest in October in temperate zones, from plantings made in previous weeks.
Spring proper, the main planting season for summer crops. After last frost, all warm-season vegetables go in. October is the highest-ROI sowing month of the year; beds planted now will produce from December through April. Soil temperature above 15掳C for tomatoes.
October is an excellent time to refresh beds with aged compost and a slow-release organic fertiliser. In temperate zones, soil pH between 6.0 and 7.0 supports the widest range of vegetables. Test and adjust with lime or sulphur as needed.
In temperate zones during spring, water deeply and less frequently to encourage deep root systems. Morning watering reduces fungal disease risk. Raised beds typically need watering every 2-3 days in the current season.
Transitional spring months in temperate zones bring changing pest dynamics. Cabbage white butterfly activity increases in spring. Check undersides of brassica leaves for green caterpillars. Companion-plant nasturtiums and marigolds to confuse and deter common pests.
Avoid the feast-or-famine cycle by sowing fast-maturing crops, lettuce, radish, Asian greens, and spinach, every 2-3 weeks rather than all at once. In temperate zones during October, a fortnightly succession-sowing rhythm ensures continuous harvests rather than a single glut. Split your available bed space into thirds and plant each third 2 weeks apart. This applies to salad crops year-round and to beans and beetroot in the warmer months.

This guide is a great starting point, Plant Planner goes further with exact sowing dates, quantities based on your family size, companion planting suggestions, and weekly email reminders.
Australia spans five distinct climate zones, and the same calendar month means completely different growing conditions depending on where you live. A gardener in Sydney planting in October faces entirely different challenges and opportunities than someone in a cool alpine area like Canberra or Hobart.
For temperate zones specifically, October is the spring transition, a critical window where the right planting decisions set up your garden for the coming season. The planting recommendations on this page account for typical temperate frost dates, average temperatures, and seasonal rainfall patterns.
