Proven Ways to Save More

🌱

Seed Saving

Harvest and store seeds from your healthiest plants each season. One heirloom tomato yields enough seeds for dozens of plants next year — completely free. Learn the dry and wet processing methods for different plant families.

Saves: $50–$200/year
♻️

Composting

Turn kitchen scraps and garden waste into premium fertiliser worth $8–$15 per bag at garden centres. A simple three-bin system produces enough compost for an average garden at zero cost within 8–12 weeks.

Saves: $100–$300/year
🌧️

Rainwater Collection

A 200-litre water butt connected to a downpipe can collect enough water to irrigate a 50-square-foot bed through a dry summer, eliminating mains water usage for your garden entirely.

Saves: $80–$150/year
🤝

Seed Swapping

Gardening communities and local seed libraries let you access hundreds of varieties without spending a penny. One packet of seeds can be shared among four families, cutting costs by 75% immediately.

Saves: $40–$120/year
🏺

Preserve & Store

Canning, freezing, pickling, and drying extend your harvest through winter months when produce prices peak. A single glut of tomatoes can yield sauce, salsa, and passata to last six months.

Saves: $200–$500/year
📐

Succession Planting

Instead of one big harvest, stagger plantings every 2–3 weeks for continuous yield. This reduces waste from gluts and ensures you're always harvesting rather than buying from shops.

Saves: $100–$250/year

Extend Your Harvest

Preserve Year-Round

Four methods to make your summer abundance last through winter.

🥫

Canning

Water-bath and pressure canning lock in flavour and nutrients for up to two years. Ideal for tomatoes, jams, pickles, and sauces.

❄️

Freezing

Blanch and freeze most vegetables in minutes. Beans, peas, corn, and herbs retain 80%+ of their nutrients and last 12 months.

🧂

Pickling

Fermentation and vinegar pickling add probiotic value while extending shelf life. Cucumbers, cabbage, and onions excel here.

☀️

Drying

Dehydrate herbs, chillies, and tomatoes. Dried herbs store for 1–3 years and are worth 10× their weight in shops.
