Q: We had a concrete wall repaired. There are now thousands of small concrete pieces in the nearby flower bed. Will the concrete leach into the soil and cause harm?

A: There might be a small rise the soil pH but it is probably nothing to worry about. Soil has a remarkable ability to buffer changes in pH. That’s why it takes so much lime to negate the acidity of clay soil in your lawn. Remove as much of the concrete as you can but don’t obsess over it.
