The plant genus 'speedwells' generally prefers an area in full sun to partial shade and well-drained soil, whether it's loamy, sandy, or clay. They tolerate a wide pH range, from slightly acidic to slightly alkaline. When planting, first prepare the area with some organic matter to make the soil nutrient-rich. Next, position the 'speedwells' plant so the top of the root ball is level with the surface of the soil. Water well after planting, and for the first few weeks while the plant establishes. Always remember, individual 'speedwells' species may have specific needs.
