Budget Garden Ideas Australia: Bunnings Picks Under $300

Gardening in tuckara.com/post/best-cheap-mattresses-australia" title="Best Budget Furniture Australia">Australia is one of the best value hobbies available — plants are relatively cheap, the climate is excellent for growing things, and the return on effort is high. The challenge is knowing where to start and how to avoid the common mistakes that cost money and kill plants.

This guide is for Australians who want a genuinely good-looking outdoor space for under $300, using Bunnings as the primary source.

Step 1: Assess Before You Spend Anything

Before buying a single plant or pot, spend 20 minutes assessing your space. Note:

• Sun hours: How many hours of direct sun does the space get per day? Full sun = 6+ hours, part shade = 3–6 hours, full shade = under 3 hours. This determines which plants will survive.
• Soil quality: Is the existing soil heavy clay, sandy, or decent garden soil? Clay drains poorly; sandy drains too fast. Both need amendment.
• Water access: How easy is it to water? This affects how drought-tolerant your plant choices need to be.
• Space constraints: Balcony or ground? Rental (can't dig) or owned?

Matching plants to conditions is the most important thing you can do — a $6 plant in the right spot outperforms a $30 plant in the wrong one every time.

Step 2: The $300 Budget Breakdown

• Soil, compost, mulch: $40–$60
• Plants: $100–$150
• Pots (if needed): $50–$80
• Basic tools: $30–$50 (if you don't have them)
• Fertiliser and water crystals: $20–$30

The Best Value Plants at Bunnings Australia

Lavender — $5–$8 per plant

Lavender is one of the best value garden plants in Australia. It thrives in full sun, is extremely drought tolerant once established, smells wonderful, attracts bees and butterflies, requires almost no maintenance, and looks beautiful from spring through summer. Plant in well-drained soil or a pot with good drainage. Purple flowering lavender borders or clusters are a classic, low-cost garden impact maker.

Native Grasses — $6–$12 per plant

Lomandra, Kangaroo Grass, and native tussock grasses are virtually indestructible in Australian conditions, require no irrigation once established, stay green year-round, and add movement and texture to any garden. Use them as border plants, in mass plantings, or in pots. Bunnings stocks a reliable range in most states.

Salvia — $5–$10 per plant

Salvias are underused in Australian gardens. They flower prolifically, come in a huge range of colours (deep purple, red, pink, white), are drought tolerant, and attract birds and pollinators. They look more expensive than they are. A cluster of three to five salvia in a border or large pot is an immediate garden impact.

Pothos and Indoor/Outdoor Trailing Plants — $5–$12

For balconies and shaded outdoor areas, trailing pothos, devil's ivy, and similar plants fill hanging baskets and trail down walls beautifully. They're almost impossible to kill, grow fast, and cost very little at Bunnings.

Herbs — $3–$8 per pot

A herb garden near the kitchen is one of the most functional garden investments. Rosemary, thyme, sage, parsley, chives, and mint all grow easily in Australian climates, are productive within weeks, and cost $3–$8 per pot at Bunnings. Grow in pots near the kitchen door for easy access. Mint must be kept in its own pot — it will take over a garden bed.

Succulents — $3–$8 each

Succulents are the ideal Australian balcony or low-maintenance garden plant — drought tolerant to an extreme degree, low cost, and increasingly stylish in pots and arrangements. Bunnings stocks a wide range. Group them in a shallow tray or wide pot for a low-maintenance display that looks great and needs almost no attention.

Pots That Look Good Without the Price Tag

Bunnings stocks a terracotta pot range that's improved significantly. Standard terracotta pots ($3–$15 depending on size) are the best-looking affordable pot option in Australia — they develop a patina with age that looks intentional, work with every plant aesthetic, and are permeable which helps roots breathe. For larger statement pots, the Bunnings concrete-look and Italian terracotta ranges at $20–$50 are strong value.

Soil and Compost — Don't Cheap Out Here

The most common beginner gardening mistake is planting expensive plants in poor soil. Good soil costs $15–$25 for a large bag of quality potting mix or garden soil at Bunnings. It's worth every cent — plants in good soil grow faster, need less water and fertiliser, and survive drought better. If planting in garden beds, add a bag of compost ($10–$15) dug in before planting. One afternoon of soil preparation saves months of plant struggles.

The Balcony Garden — $150 Starter Kit

For renters or apartment dwellers with a balcony: three large pots ($15–$25 each), a bag of quality potting mix ($18–$25), and five to seven plants — two lavenders, two salvias, a trailing plant, and a herb pot. Total: $100–$150. The result is a balcony that feels alive, smells good, and provides fresh herbs for cooking.

Step 2: Create Your Budget Breakdown

With a $300 budget, here's how to allocate your funds for maximum impact:

• Seeds and seedlings: $80-100 (30-35%)
• Soil and compost: $60-80 (20-25%)
• Basic tools: $50-70 (15-20%)
• Pots and containers: $40-60 (15-20%)
• Mulch and fertiliser: $30-50 (10-15%)
• Seeds for ongoing planting: $20-30 (5-10%)

This breakdown ensures you're not overspending on any single category whilst covering all the essentials for a thriving garden.

The Best Value Plants at Bunnings

Vegetables That Give Maximum Return

Focus on vegetables that produce continuously rather than single-harvest crops:

• Cherry tomatoes ($4.98 per plant): One plant can yield 2-3kg of tomatoes worth $15-20 at the supermarket
• Lettuce mix ($2.48 per punnet): Cut-and-come-again varieties provide salads for months
• Herbs bundle ($12 for basil, parsley, and mint): Fresh herbs cost $3-4 per small pack at Coles
• Spring onions ($2.48): Regrow endlessly from kitchen scraps
• Silverbeet/Rainbow chard ($2.98): Hardy, colourful, and productive year-round

Flowers for Instant Impact

Choose plants that flower for extended periods:

• Marigolds ($2.48 per punnet): Bright, pest-deterrent, and flower for months
• Petunias ($3.48 per punnet): Continuous bloomers in multiple colours
• Impatiens ($3.98 per punnet): Perfect for shaded areas
• Portulaca ($2.98 per punnet): Drought-tolerant with vibrant flowers

Essential Tools Without Breaking the Bank

Bunnings' Taskmaster range offers excellent value for beginner gardeners:

• Hand trowel ($4.90): Essential for planting and weeding
• Secateurs ($9.90): For pruning and harvesting
• Garden fork ($12.90): Better than a spade for breaking up soil
• Watering can (9L) ($8.90): More water-efficient than a hose for small gardens
• Garden gloves ($3.90): Protect your hands and improve grip

Total tool cost: Under $45, leaving more budget for plants and soil.

Soil Solutions on a Shoestring

Improving Existing Soil

Rather than replacing all your soil, improve what you have:

• Seasol Premium Potting Mix ($6.50 for 25L): Mix with existing soil at 50:50 ratio
• Bunnings Garden Soil ($4.90 for 25L): Cheaper option for larger areas
• Organic compost ($3.50 for 25L): Add 20% to any soil for nutrients
• Cow manure ($2.90 for 25L): Slow-release fertiliser and soil conditioner

Container Growing Solutions

If your existing soil is hopeless, containers are your friend:

• Large terracotta pots ($12-18): Classic look, good drainage
• Plastic planters ($6-12): Lightweight, retain moisture better
• Self-watering pots ($15-25): Reduce watering frequency
• Hanging baskets ($8-15): Maximise vertical space

Seasonal Planting Guide for Maximum Success

Autumn (March-May)

Perfect time to start in most Australian climates:

• Cool-season vegetables: lettuce, spinach, peas, broad beans
• Herbs: parsley, coriander, chives
• Flowers: pansies, calendula, sweet peas

Winter (June-August)

Focus on maintenance and planning:

• Prepare beds with compost and manure
• Plan your spring garden layout
• Grow microgreens indoors on windowsills

Spring (September-November)

The traditional planting season:

• Warm-season vegetables: tomatoes, peppers, cucumbers
• Annual flowers: marigolds, zinnias, sunflowers
• Herbs: basil, oregano, thyme

Summer (December-February)

Heat-tolerant options only:

• Drought-resistant natives
• Succulents and cacti
• Heat-loving herbs like rosemary

Money-Saving Propagation Techniques

Growing from Cuttings

Many plants can be propagated for free:

• Herb cuttings: Mint, basil, and rosemary root easily in water
• Succulent propagation: Break off leaves and let them root in soil
• Geranium cuttings: Take 10cm cuttings in autumn, root in potting mix

Seed Starting Indoors

Start expensive plants from seed using household items:

• Use yoghurt containers as seed trays (poke drainage holes)
• Newspaper pots cost nothing and can be planted directly
• Egg cartons work perfectly for small seeds
• Clear plastic containers create mini-greenhouses

Common Mistakes That Waste Money

Overwatering

The biggest killer of plants and money-waster. Check soil moisture by sticking your finger 2cm deep - if it's damp, don't water. Most Australian natives prefer to dry out between waterings.

Wrong Plant, Wrong Place

Placing sun-loving plants in shade (or vice versa) leads to weak, pest-prone plants that need replacing. Always read the plant tags and match them to your assessed conditions.

Buying Mature Plants

Large, established plants cost 3-5 times more than seedlings but don't necessarily perform better. Young plants often establish faster and stronger root systems.

Ignoring Companion Planting

Some plants help each other grow, whilst others compete. Plant marigolds near tomatoes to deter pests, and avoid planting mint directly in garden beds where it can take over.
