Lavenders require the soil to dry out between bouts of watering in order to keep their roots healthy. Lavenders require a light, sandy soil that drains quickly and they won’t grow well in soil that is heavily compacted or has a high content of clay.Ĭlay soils drain slowly and are far less porous then soil that has been amended with with sand or gravel. ![]() However they are very particular about certain soil conditions.

Other common problems include, slow draining soils, acidic soils over watering, the use of fertilizer or nutrient rich soil and not planting lavenders far enough apart. Lavenders require sandy, well draining, alkaline soils that are nutrient poor and full sun in order to grow properly. The reasons lavenders won’t grow is usually because of a lack of sun, planting lavenders in the wrong type of soil or growing lavender species that is not cold hardy in a cool climate.
