3 Things You MUST Do Now to Prepare Your Garden For Hot, Dry Weather


One of the biggest challenges as an Australian gardener, is our often unpredictable climate, particualrly hot dry weather. While Tasmania has had an above average rainfall, Victoria has experienced an unusually dry spring this year. This comes off the back of both states having a dry autumn and winter. The ongoing dryness in Victoria results in continual moisture being depleted from the soil [1]. As a result, preparing for hot and dry summer conditions is more critical than ever. Beginner gardeners, in particular, can struggle with managing water needs, often overwatering or under-mulching their plants. Let’s look at three actionable steps to help your garden thrive in the heat.


1. Prioritise Mulching

One common mistake new gardeners make is underestimating the power of mulch. Adding a thick layer of organic mulch, like straw, wood chips, or grass clippings, helps retain soil moisture, regulate temperature, and suppress weeds. Apply a layer about 5-7 cm thick, keeping it clear from plant stems to prevent rot. This is especially effective as soil moisture declines in drier springs.


2. Efficient Watering Practices

In dry conditions, water deeply but less frequently to encourage deep root growth, which makes plants more drought-resistant. Water early in the morning or late in the evening to reduce evaporation (and even consider both during particularly hot days). Beginners often fall into the trap of shallow, frequent watering, which can lead to weaker plants.


However, be mindful that particularly dry soil will not absorb water and instead the water runs off (potentially taking topsoil with it). This is easily observed when you scrape back the wet soil, it remains dry.

3. Shade Where Necessary

Hot sun can be brutal on young plants or sensitive crops like lettuce. Providing temporary shade with shade cloth, old sheets, or netting can protect your plants during the hottest parts of the day. Even small-scale gardeners can create microclimates by positioning taller plants to shield more delicate ones.


Why Prepare in Spring for Hot, Dry Weather?

Victoria’s conditions this spring highlight the need for proactive measures. Dry weather has increased the risk of plant stress, reduced soil moisture, and heightened fire risks. Preparing your garden ahead of summer ensures you conserve resources and help your plants withstand tough conditions.
