SPRING GARDENING IN THE SOUTH WEST

HOW TO MAKE YOUR GARDEN BLOOM

As the winter rains ease and the days start to warm, spring arrives and gardeners know exactly what that means: it’s time to get outside, roll up your sleeves, and bring your garden back to life.

From Bunbury to Busselton, Margaret River to Manjimup, this season is your chance to revive your soil, plant new life, and prepare your garden for the long, dry summer ahead. Here’s how to make the most of it.

Start with Healthy Soil

The South West’s climate means wet winters and dry summers, which can leave your soil compacted and depleted.

Loosen and aerate the soil using a garden fork or tiller.

Mix in organic compost or aged manure to boost nutrients.

Apply a thick layer of mulch (5–10 cm) to lock in moisture and suppress weeds — it’ll also help your plants cope with the summer heat.

Tip: In sandy coastal areas (like Busselton or Bunbury), improving soil structure with bentonite clay and compost makes a world of difference.

Choose the Right Plants for the Season

Spring is planting season, and the South West offers ideal growing conditions for both edible gardens and ornamental blooms.

Veggies & Herbs

Plant your warm-season favourites:

Tomatoes, zucchinis, cucumbers, beans, pumpkins

Herbs like basil, parsley, mint and chives thrive now

Try fast-growing greens such as lettuce and rocket for instant rewards

If you’re near the coast, choose salt-tolerant varieties, and in cooler inland areas (e.g., Bridgetown), start seedlings under cover until frost risk passes.

Flowers & Natives

Brighten your beds with marigolds, petunias, salvias and daisies.

For low-maintenance colour, plant WA natives like kangaroo paw, Geraldton wax, or bottlebrush — they’re adapted to local soils and attract birds and bees.

Climbers and shrubs like bougainvillea and hibiscus also establish well in spring.

Water Wisely

Spring brings fluctuating temperatures, so water deeply but less frequently to encourage strong root growth.

Water early morning or late evening to reduce evaporation.

Group plants by water needs.

Check and repair drip irrigation systems before summer arrives.

Waterwise tip: Install a simple rain gauge — you’ll be surprised how much natural rainfall can offset your watering.

Stay Ahead of Pests and Weeds

As the days warm up, so does the pest activity!

Keep an eye out for aphids, caterpillars and slugs on young plants.

Use natural controls like neem oil, pyrethrum spray or companion planting (e.g., marigolds deter aphids).

Mulch generously to reduce weed growth and moisture loss.

Weeding early in spring prevents a battle later in summer.

Prune, Feed and Refresh

After winter dormancy, your plants are ready to grow — give them a head start.

Prune back winter shrubs and dead wood to encourage new growth.

Feed lawns and garden beds with a slow-release organic fertiliser.

Deadhead spring blooms regularly to keep flowers coming.

Tip: For citrus trees, a balanced fertiliser in early spring will boost flowering and fruit set.

Plan Ahead for Summer Heat

Spring gardening isn’t just about colour — it’s about preparing for summer survival.

Plant shade trees or install garden structures like pergolas for natural cooling.

Use mulch and groundcovers to protect soil from drying out.

Collect rainwater now for use during dry spells.

If you’re establishing new lawns, spring is ideal — the soil is warm, and there’s still enough rainfall for root development.

 Spring is one of the most rewarding times of year to garden. The mild weather, clear skies, and bursts of colour make it easy to fall in love with your backyard all over again.  Take a moment to enjoy the scent of flowering natives, the buzz of bees, and the satisfaction of a thriving garden that’s ready to carry you through summer.

 Gardening in spring in the South West isn’t just about pretty flowers — it’s about building resilience for the months ahead. With a little planning, local knowledge, and love for the soil, your garden will not only survive but flourish through the hottest parts of the year.

 So grab your gloves, turn the soil, and let your garden — and your spirits — bloom this spring.
