spread reaches spacing
At 1 m (3 ft), mature canopies (about 1.3 m across) stay within the planner’s overlap limit.
Growth follows s(t) = sm − (sm − s0)·e^(−k·t) with k = 0.25 (medium growth), from a #7 install size of 0.60 m wide. Real growth varies with site and care. Emerald Green arborvitae facts · Reading mature plant sizes
Lay out hedges and masses at real spacing
In the planner, rows, masses and grids resolve into individual plants at the spacing you choose — and the overlap check runs on every pair.
