The journal will re-launch from 27 April as a quarterly publication, reduced from 11 editions a year.
In addition, the Landscape Institute's monthly printed newsletter Vista is being scrapped and replaced with a fortnightly online service.
Director of policy and communications Paul Lincoln said the move away from printed material was part of a drive to save cash. He would not reveal how much money was being saved, but told HW: "We are going to be saving an awful lot of paper and postage.
"Although clearly we have needed to make changes I am excited by the fact we have responded very positively and will provide a really good quality journal and useful news service."
A preview copy of the journal will be available at the Street Design exhibition in Birmingham tomorrow (21 April), where the Landscape Institute is running a series of seminars on green infrastructure in street design.
The seminars are:
