The garden is maintained by a volunteer group of local residents called Friends of the Gamble Garden who hold working bees each Tuesday morning from 9-11am. There is also a meeting of the Friends on the second Tuesday of each month (except January), held at the cottage at 11am . New members are always welcome at the working bees or at the meetings. There is an annual membership fee of $5.

The current office holders are:
