Authors and Reviewers

Editorial team

Plant records, relationship records and guides are written by the Garden Planner editorial team following the published methodology. Every record names its reviewer and review date.

Independent review: pending

We have not yet completed an independent horticultural review. Until a qualified reviewer has checked a record, it is labelled "pending independent horticultural review". We do not list reviewer names or credentials that are not real. When reviews take place, reviewers will be named here with their affiliation, the records they reviewed and the date.

Conflicts of interest

Nobody involved receives payment from seed, tool, fertiliser or pesticide companies. The site carries no advertising at present; if advertising is added later, it will never influence a status, a tier or a recommendation, and ad placements will be kept away from planner controls and evidence.
