Cleve's return talk to us took him away from his beloved Bushy Park allotment and his planning of a garden for the Chelsea Flower Show. He said that the common prediction of climate change includes extremes of weather, drought in summer, flood from more winter rain, wind, pests such as lily beetle, and diseases such as mildew. Bluebell flowering may be affected by earlier leaf shade in spring. Beeches may suffer, and limbs of trees crack due to drought.

Living , as we do, in the south-east, the news is worst, because temperatures there are predicted to rise by 1.5 degrees by 2020, 4.5 degrees by 2080. Yes, there will be more chance to grow Mediterranean and Australian plants such as eucalpyt, many fruits, and sweet chestnut. In fact, gardens may find it easier to adapt than our landscapes, because gardens have micro-climates- influenced by wind and rain, buildings, trees etc. But the right plant must be put in the right place.

Cleve reminded us that, to help reduce climate change and its effect, we can recycle waste, plant trees (and not be afraid of using their shade for planting), create habitats for birds and insects, store rain, and plant together those with similar watering needs. We can grow food (to reduce transport and packaging), and reduce cutting and fertilising lawns.

Our aim should be to reduce production of greenhouse gases such as carbon dioxide and methane. We should avoid bonfires, patio-heaters, and (oh!) long-haul flights - even to see exotic gardens! We should avoid impermeable driveways. We should re-use and reclaim existing materials and local materials, and swap seeds and plants with our acquaintances. And, with the future in mind, we should teach children all of this.

Lastly, Cleve recommended a book linked to the R.H.S. called 'New gardening- how to garden in a changing climate' by Matthew Wilson, priced £18.99. Good luck to Cleve at Chelsea!
