Melbourne's notorious 'four seasons in one day' weather means always have frost cloth ready from April through October, sudden cold snaps can damage tender seedlings even in spring.
The dry, hot northerly winds in summer (particularly January-February) can desiccate plants overnight, water in the morning and mulch heavily.
Melbourne's cold winters are perfect for broad beans and garlic, both need cool temperatures to produce well, making April-June planting essential.
Use raised beds to overcome Melbourne's often clay-heavy soils, they warm faster in spring and drain better in the wet winters.
