A New Horticulture: Designing Landscapes for Climate Change

The world is finally, at the last minute, waking up to the impending effects and consequences of climate change. In the scramble to work out what we must do (apart from the obvious cessation of burning fossil fuels), one thing, one factor is looming large: we need to put carbon back into the soil, where

Concrete and alternatives

Concrete is a wonderfully versatile material, which has been in use since Roman times and with it we can build amazing structures that would otherwise be impossible. Unfortunately it also carries a huge environmental cost, caused mostly in the cement binding used. Whilst gravel extraction is also an issue, for that there are some alternatives

Rain gardens

Rain gardens are a relatively new approach on how to deal with water in the environment. In the last 10-15 years, there has been a big rise in the use of SUDS (sustainable urban drainage systems), the practice of delaying the entry of rainwater into the drainage system by the use of swales, ditches and

The beauty of resilient planting design

The emergence of the idea of resilient planting is a response to a number of different pressures which all have one underlying cause – climate change. Whatever the cause – and I’ll get on to that later – I see it as the most exciting change to the way we design our gardens and landscapes.

Biomembranes for living buildings

NOTE: This article was first written in 2006, so some aspects have been updated to reflect current realities. Biomembranes is a term I’m borrowing from biology (the structure bounding a cell) to describe the outer skin of future self-sustaining buildings. I have stated elsewhere that I believe that for the built environment – and therefore

The future of gardens in an age of climate change

This article was first published in 2007 and has been updated 2018. Future gardens will be an integral part of a living bio-system that is part house, part garden, an energy conserving and production environment.  It will also be a resource for water retention and cleansing, food production area, biomass and environmental haven. Above all,

Naturalized exotic plants in arid climates

A problem, or an opportunity for a new landscape paradigm? I was recently working on a tree project in Abu Dhabi when I came across a derelict site which intrigued me with it’s range of exotic self-seeded, non-native plants.  The site was next to the Corniche and sandwiched between the Formal Park, my hotel and

The (near) future of urban landscapes

UPDATE September 2022:  Given the increasing urgency of climate change and the overwhelming stresses this will place on our civilisation for the near, medium and long-term future, I now doubt this scenario will ever come about.  A glimpse of what might have been, maybe, had we taken climate seriously and managed to move through that

Maintenance of Green Walls

We are now a decade into the explosion of living or green walls.  There have been many successes and some notable failures along the way, some of of which may be system-induced and some caused by inadequate or inappropriate maintenance regimes. Assuming we now have systems that work at least reasonably well, what is required by

Newsletter Launched

I launched my newsletter this week on vertical greening, sending it out to clients and those who’d signed up here or on the website.  From the number of views and feedback, (considerably higher than industry standards) I’d say it was a success!  The aim is to inform interested parties of news and developments in the
