Building work cement slag is near my natives. Is there anything I can do to help them survive this?

Answer: The cement slag or runoff can have a very detrimental effect on your soils. The lime in the cement can raise the pH in your soils to the point that nutrients become unavailable to the plants. Test the pH of your soils, you can by a test kit at most hardware and garden centres. Depending on the results you can apply Yates Soil Acidifier Liquid Sulfur to lower the pH back to the 6.0-7.0 range.
