This change may happen quite rapidly. If a new generation takes control of the estate and decides to move away from traditional "family" methods of working, into a commercial business world whereby every member of staff — especially senior employees such as head gardeners — is suddenly obliged to act in a commercial manner.
In complete charge
Essentially, a head gardener should be in complete charge of the garden. This includes taking responsibility for the day-to-day operations, plans, ordering of materials and supplies, decision making, minor purchases without reference to anyone else (hold a cash till and be authorised to spend up to a certain amount on minor items).
I will continue this article in next month’s issue by describing the transition from head gardener to gardens manager.
