How to Balance pH for New Zealand Flax Plants

To balance the pH for New Zealand flax plants, it’s essential to maintain a slightly acidic to neutral soil pH, ideally between 6.0 and 7.0. This step-by-step guide provides advanced hands-on details and home remedies to help DIY users achieve the perfect pH for their New Zealand flax plants.

Soil Testing

Before planting, test the soil pH using a home testing kit or by sending a sample to a local agricultural extension service. Knowing the current pH level is crucial for determining the necessary amendments.

If the soil pH is too high, you can lower it by adding organic matter like compost and sand. This will improve drainage and slightly acidify the soil. For container plants, use a rich, organic mix over traditional potting soil.

Home Remedy

If the pH is still too high, consider using a natural acidifier like lemon juice. Add lemon juice to water at a ratio of 1 tablespoon per gallon to lower the pH by about 1 point. Test the pH after adding lemon juice to ensure it’s within the desired range.

Keep the soil consistently moist but not waterlogged, especially during summer’s heat. Avoid allowing the plant to sit in wet soil for a prolonged period.


Use a liquid organic fertilizer monthly throughout the summer to provide necessary nutrients and maintain soil pH.

Quantity, Days, Shade, and Temperature

  • Quantity: For soil amendment, add a 50/50 mixture of compost and sand at a rate of 2 parts soil to 1 part amendment. For lemon juice, add 1 tablespoon per gallon of water.
  • Days: Test the soil pH every 2-3 weeks during the growing season to ensure it remains within the desired range.
  • Shade: New Zealand flax prefers full sun but tolerates partial shade, especially in hotter climates.
  • Temperature: Keep the plants at temperatures above 50°F (10°C) during winter dormancy.
