Gypsum is a slow-release source of sulphur and calcium which play a key role in improving soil structure, aeration and water retention. So you can grow better, healthier crops.
When Gypsum dissolves, it releases equal proportions of calcium and sulphate. Calcium sulphate improves the structure and consistency in soil and most other growing media allowing better water penetration and retention.
Gypsum is an environmentally friendly, natural mineral that is mined from ocean deposits formed centuries ago. It's non-toxic and not harmful to people or animals.
- Loosens clay and compacted soils.

Tui Lime is a staple ingredient for healthy, thriving gardens, and is a natural source of calcium for strong, healthy, plant growth. Lime improves soil structure, encouraging decomposition of organic matter and earthworm activity. Lime naturally adjusts soil pH levels, boosting plant growth and improving nutrient absorption by plants. Tui Lime can also be used on lawns to encourage lush green growth, and in compost bins to speed up the decomposition process.
Use in your garden beds to reap the rewards of healthy soil and plants.
Tui Blood & Bone is an essential garden ingredient, promoting healthy plant growth and conditioning your soil to encourage earthworm and microbial activity, so your garden can perform at its peak. The addition of Tui Blood & Bone to your garden provides a natural source of nitrogen for healthy plant growth, and phosphorus for strong root development.
Use throughout your garden to reap the rewards of thriving plants and healthy soil.
Tui Compost is the natural garden ingredient - the staple in every Kiwi shed! Healthy, conditioned soil is essential to get the most from your plants.
Tui Compost adds nutrient-rich organic matter to replenish your soil with nutrients used during the growing season. The combination of organic matter, blood and bone and gypsum will: help break up heavy or clay soil; improve drainage in compacted soil; and increase water holding capacity in sandy soil. It also increases microbial activity, and encourages earthworms - a gardener's best friend!
