Aim for three to four plants per square foot of growing area (roughly 6 to 12 inches apart). It takes pachysandra about three years to fill in a planting area.

How do you encourage pachysandra to spread?

The plant actually spreads by underground runners, and it is true that a light shearing or pinching in early spring can encourage the plants to send up more runners and thus thicken the planting faster. This can be done by hand or in some cases with a lawn mower.

How wide does pachysandra spread?

Each Windcliff pachysandra will form underground stolons or rhizomes and spread 2-feet wide with glossy, thick, serrated leaves.
