Likely not, but adding some compost as a soil amendment to the pockets and top of the Garden Tower every year is recommended. In many instances, the condition of the soil can improve with time for several reasons. However, excessive drying during the off-season should be avoided to prevent soil structure damage and keep compaction to a minimum. Lighter soils will have less compaction over time and thus lower maintenance. Plant roots and compost will contribute organic structure to the soil and worm activity will help maintain aeration and a steady rate of soil renewal. Avoiding woody-rooted perennial species (such as mints), or removing woody root masses between growing seasons is suggested soil maintenance for the Garden Tower.
