Seasonal Garden Care
Perennials and ornamental grasses reward gardeners who work with the seasons rather than against them. In the Riverina, where we experience hot, dry summers, cool winters and distinct seasonal shifts, understanding the rhythm of the year is essential to building resilient, long-lived plantings.
Each season brings its own priorities—moments to act, moments to observe, and moments to step back.
Spring: Growth and New Beginnings
Spring is a time of energy and expansion. As soil temperatures rise, perennials and grasses emerge quickly, putting on fresh growth and establishing new root systems.
This is the ideal time for planting, dividing overcrowded clumps, and applying organic compost or mulch to support healthy growth. Keep an eye on early weeds, which compete fiercely at this time of year, and ensure new plantings are watered deeply but infrequently to encourage strong root development.
Avoid heavy pruning in early spring—many plants are still drawing energy from last season’s growth.
Summer: Observation and Water Management
Summer in the Riverina is about restraint and awareness. Heat and dry conditions place plants under stress, so thoughtful watering becomes critical. Deep, less frequent watering supports deeper roots and better drought resilience, particularly for ornamental grasses.
This is also a time to observe rather than intervene. Notice which plants thrive, which struggle, and where shade or shelter may be needed in future plantings. Deadheading can encourage repeat flowering in some perennials, but avoid excessive cutting back during peak heat.
Autumn: Structure, Planting and Preparation
Autumn is one of the most valuable gardening seasons. Cooler temperatures and warmer soil make it an excellent time for planting perennials and grasses, allowing roots to establish before winter.
This is when structure starts to matter. Leave seed heads and dried foliage intact—ornamental grasses and many perennials provide movement, texture and habitat through the colder months. Light tidying is fine, but avoid the temptation to cut everything back.
Winter: Rest and Restraint
Winter is a time of patience. Many perennials and grasses enter dormancy, and standing growth helps protect plant crowns from frost while also supporting beneficial insects and wildlife.
Knowing what not to do is just as important as knowing what to do. Heavy pruning is best saved for late winter or early spring, once the risk of severe frost has passed. Cutting back too early can expose plants to damage and weaken their performance in the coming season.
