In small garden beds, you can estimate the amount of lime you need with the following information. These figures refer to the amount of finely ground limestone needed to raise the pH of 100 square feet of soil one point (for example, from 5.0 to 6.0).

  • Medium loam soil – 7 pounds
  • Heavy clay soil – 8 pounds

How and When to Add Lime

For most gardeners, fall is a good time to add lime. Working lime into the soil in the fall gives it several months to dissolve before spring planting.
