Spacing calculator

How many plants for a run, how many to fill an area, and how far to keep a tree off a wall, a pool, or a sewer line.

Measure the length you want covered. Spacing is center to center, meaning trunk to trunk, not the gap between the pots.

Length of the run, in feet

How solid do you want it

Tighter fills in sooner and costs more. Looser takes an extra season.

For groundcover, perennials, and mass plantings. Enter the bed size and how far apart the plants go.

Width, in feet

Depth, in feet

Spacing

Before you dig. Enter the mature width from the plant page and this returns how far back it needs to sit.

Root behavior

Center to center Measure from the middle of one plant to the middle of the next. Most people measure the gap between pots instead, plant too far apart, and end up with a hedge that never closes.
