Common questions

Bare root plants are field-grown and lifted dormant — the cheapest way to plant a hedge. Pot grown plants have an established root system and can be planted year-round. Root ball plants are mature field-grown plants lifted with a soil ball for instant height.
Pot grown plants can go in the ground at any time of year. Bare root is supplied dormant from November to March, and root ball plants are lifted in that same window.
