Gardening – Lime

Why lime matters in New Zealand gardens

Across Aotearoa, acidic soils can stunt plant growth and lock up vital nutrients. Applying garden lime (calcium carbonate) raises pH, improves microbial activity and unlocks phosphorus, while dolomite lime adds magnesium as well. Whether you’re nursing roses, fruit trees or a vege patch, understanding lime helps you grow stronger, more productive plants.

Common types of garden lime

• Agricultural (calcitic) lime – pure calcium carbonate, ideal for general pH correction.
• Dolomite lime – contains roughly 10% magnesium; choose when soil tests show magnesium deficiency.
• Hydrated lime – fast-acting but caustic; best for composting or disease control rather than broad lawn use.

Choosing the right product

1. Test your soil first. DIY kits or laboratory tests tell you current pH and magnesium levels.
2. Match the grade. Fine powders react quicker; coarse chips suit windy sites where drift is an issue.
3. Check application rates. Typical lawns need 50–100 g/m², while heavy-clay vege beds may require up to 250 g/m².

Application tips for garden lime

• Timing – Spread in autumn or early spring so rain works it into the soil before peak growth.
• Even coverage – Use a drop spreader for lawns; for gardens, broadcast by hand and rake in lightly.
• Water afterwards – Moisture accelerates dissolution and reduces dust.
• Avoid overlap with fertilisers – Leave at least two weeks between lime and ammonium-based fertilisers to prevent nitrogen loss.

Safety first

Wear gloves, goggles and a dust mask when handling hydrated or finely ground lime. Store bags in a dry spot to maintain potency.

Project inspiration

Combine lime-washed pathways with lime-green planters for a cohesive look, or contrast bright lime tools against natural timber decking. Our suppliers offer sample swatches and expert advice to help you nail the palette.
