— When To Add Lime To Clay Soil. Lime can be added to clay soils any time of the year, but the best time is in the fall. This gives it a chance to start working over the winter before spring planting. Lime moves down through the soil slowly so it needs time to incorporate. Apply lime at least 2-3 months before growing plants that need high pH levels.
