A one-gallon ground cover is planted at what spacing?

When planting one-gallon ground covers, a spacing of one foot on center (o.c.) is recommended for optimal growth and coverage. This spacing allows sufficient room for the plants to establish their root systems and spread their foliage without overcrowding. By maintaining this distance, the ground covers will be able to grow evenly and fill in gaps more quickly, creating a lush, uniform appearance in the landscape.

Ground covers are typically planted closely together to form a dense mat that suppresses weeds and reduces soil erosion, so one foot o.c. strikes a balance between providing adequate space for growth and achieving the desired aesthetic and functional benefits of ground cover planting.
